OK, I will never tell a short story when a LONG story will do. ;D but please bear with me:
Back in the early 1960's my Dad and brothers joined the famous Strathmoor Model Club in Detroit. By then all the legendary stunt flyers and I-Beam builders had left, so we never rubbed shoulders with Daly, Palowski, the Ebejers, etc. My brother Arch built an Ambroid Ares (ugh!), and later Rick Sawicki taught him how to design & build an I-beam from scratch. Arch built a couple, then we moved on to sheeted/sparless wings. Other I-beamers in the area included Fred & Rick Bachl, and (sometimes) LeRoy Gunther. Of course we saw Billy Werwage and the big Ares most weekends at contests. Jerry Worth, & Gerry Phelps were flying beamers then back then too. We saw Steve Wooley's Argus, and Steve finished the Cobra in my Dad's basement one summer. Of course a BUNCH of I-beams were coming out of Indy too - Jack Sheeks, Jim Vornholt, John Davis and others. Later we met Rod Pharis, and much later we got to know Rollie MacDonald when he came back in the early 1970's - he and son Bob returned to I-Beams in the mid to late 1970's. Of course, Billy W was ALWAYS there with a whole array of I-beams along the way! After much trepidation I finally built an I-Beam, the Sheeks "Swinger", a little over a year ago, and found it was fun - wanted to try one of my own some day - enter the Mythbuster
* Most everyone flying an electric bird has basically taken a bird designed for IC and swapped powerplants. No harm there, but it seems that there is a level of optimisation left on the table. Thus this is my first ground up attempt at a electric design; by that I mean it has elements that tilted toward electric power that I would find unacceptable in a IC powered bird.
* Aerodynamically it was logical to continue the design evolution from where I left it with the Eclipse series. Starting with that efficient airframe would be great for electric, advancing the aerodynamics should help reduce power requirement, and result in much less wasted power thrown over the side. Drag removed from the airframe would be handed over to the Phoenix speed controller with its excellent governor to control potential wind-up.
* Among other things with electrics the traditional chin scoop is not necessary and it is ineffective. From a cooling perspective something like a radial cowl makes a lot more sense. Another bonus; with a radial cowl the spinner now becomes optional, and keeping excess mass off the motor shaft seems like a good idea, electric or IC powered!
Let's tie a bow on this: I made a few sketches to reconcile and meld the Classic I-Beam forms and radial cowl all around the aerodynamic forms I needed, then blend it all into something I liked. I wanted a retro look but still make it look contemporary. One early sketch I called "Miss Strathmoor" portrayed what a modern Strathmoor I-Beam "racer" might look like. A mix of straight line and curved line elements added some "vintage" (think DeHaviland or Supermarine S-6B) Swept tips and tail adds some "speed" to the look, as well as makes them look a little more modern. The I-Beam wing, stringered fuselage, & large wheelpants over large wheels all added some "attitude". Quite honestly, my sketch showed a conventional tail, the V-tail was a late addition. It was consistent with the slippery look and also provides that last bit of signature - less anyone question WHO's airplane this is! At 63" tip to tip and 47" nose to tail, it is among the largest birds out there. At 44 oz it is also among the lightest - Sparky should like that!
Initial flight tests have been very promising. RPM settings have resulted in faster than predicted lap times, hinting the low drag goal has been achieved and that we will have to update the RPM spread sheets for efficient airframes. Inside of the first 5 laps I felt comfortable with it, very groovy, but as expected due to high AR and V-tail, there is corner to burn; yet it modulates very well too. It also carries energy well through a corner. This all means that I gotta mess with the base RPM setting, then will fine tune the Governor gain. 8)
Oh yeah, gotta practice some too..! :o
So, whatcha think?
-
Outstanding Dennis, While I'm not attracted to electrics myself, I really like your approach. It certainly carries your signature. This is a model I would be apt to redesign for use with an IC engine, pardon my reversion of your forward thinking. Very attractive airplane and I really like the high AR
-
That is one sweet looking plane. I like the idea of designing a plane
specifically for electrics rather than adapting a previous design. This
hobby, like others will gravitate more and more to electrics as time
passes. Nice plane!
Steve
-
Holy crap, Dennis... :o
That is insane cool.
High AR Adamisn designs back in the mix!! Old School!!! Makes me want to buy bell bottoms. #^
-
I like it,
and I especially agree that there has been little exploration of dedicated airframes. well in fairness there are a few that have but I agree, the parameters to maximize the power delivery of the electric is still an exploration. Really anxious to see how it goes for you
If I may, what is the final AR of your planform? My next electric bird has a slightly higher AR than norm, but I dont htink its quite that long and beautifull,,, High AR stunters remind me of the leggy dancers,, ;) just have to love them,,,
-
"High AR stunters remind me of the leggy dancers"
WOO HOOO!! Never thought of it that way Mark, you're so right! A sort of poetry in motion.
-
Finally something different! Looking at the photos closely you have quite a few of things going on here. Sharp leading edge, high aspect ratio wing and stab, v-tail, long tail, moment, full span HAR flaps, and laminar airfoil. Love the color experiment and trim graphics, also the stripes on the bottom.
It is quite appropriately titled "Mythbuster"!
From a total design concept for electric power which is very different from IC, this for me is the plane to watch. Hope to see it in person some day.

well of course it would look better with a beautifull XOAR wood prop on it too,, but thats a small thing,, LL~ S?P

Very cool Dennis! It kinda reminds me of a cross between a Quickie and a slope racer! Great colors and a sleek design too. And what a fitting name! H^^

Looks great Dennis, is it headin to Brodak?

A couple of questions. What did you use for the trailing edge.Does the V tail do any thing for performance or is it just a look thing? I remember your articles on your High Aspect Ratio planes years ago and remember you saying as the plane got longer the better it flew. I know you have used the V tail before,that is why I asked. I asked about the trailing edge because I have built a lot of I/Beams and ran into problems with the trailing edge as the wing got over 56" span. I used 1/2" sq as on the smaller ones. On one model I sheeted over the 1/2". I just thought of another question. Are these flaps thick at the leading edge like your earlier planes.
Ed
-
WOW thanks for all the kind commentary. H^^ See if I can catch all the Q's:
Randy: I used the "slimer" Eclipse as a starting point, would go back there and re-style like this if I wanted the same bird for an Evo 36 or similar
Mark: Its a 7:1 AR . I dunno, I like the look better than the broad wing birds. It WOULD look nice with a Xoar prop. BTW have you been to your "Propellor Addiction" meeting yet this week???
Brad: DOn't think of it as "Old School" its "Back to the Future!" I do not know Mr Hyde, but I DO know Mr. Bill Zimmer who always told me I needed MORE STRIPES!!! Oh yeah; when you buy your new T-Rex bell bottoms they have to be WHITE bell bottoms - don't forget the matching shirt & shoes too...
PTG: The flaps are nominally 20% wide, with the outer 6" or so hinged as tabs. The airfoil is 15% and derived from a NACA profile. It does not exhibit currently fashionable ultra blunt LE so it does look really sharp & thin by those standards. Frankly after building a slew of 18% wings this was an area of concern - but it looks pretty good so far. Again the drill was to try to make the airfoil it do its lifting job, minus a little drag and use the Phoenix governor. BTW good catch on the bottom stripes, here's another pix... Unfortunately I am not sure when we will get to fly together again. Looks like my (lack of) job will prevent me from going to NATs or Team Trials. Ah, to be in the auto industry in MI in times like this...
Steve M: I think electric design will evolve to a certain niche, just as Pipes & 4-strokes have gotten a little specialized one way or the other. What I REALLY like today is the almost unlimited selection of engines in ALL sizes from 25's through 90's - plus electrics! This is a great time to be exploring new aircraft without having to worry about the power choices.
Richard G: Your comment about slope racer reminded me of something Ted F said back when I had my first high AR bird. He looked over the Orange Crate and asked "Where's the tow hook?"
Matt: HOPING to have it at Brodak, looking forward to meeting you there too.
As for the "long legged dancer" comment - I'll bet Ty will have something to add... LL~
-
Pink? PINK!? Well, I like it anyway. As you know, I share your high AR views (and take no end of flak for it around here). I still think the Orange Crate is a great place to start for an electricuted design.
I'm afraid my new plane that I'm just starting to build is much more middle of the road (having totally caved into peer pressure and comments like "why don't you build a REAL stunter?). But I have thoughts....

Great minds and all that sort of stuff.....Two Skinny Divas and first Zealot are 15% at root and 9% at tip. STRIPES on the bottom??
Too bad you won't make it to the NATS. In the old days I would sit on the runway and wait for that U-Haul trailer with Big Art driving as it cruised over to the stunt circle. Then he opened the doors to reveal all those beautiful planes. For me, it the Opening Ceremony and the absolute highlight of those good 'ole Nats. I really miss those days!
-
Well I notice that you haven't been kicked out of this forum (yet S?P), and maybe that is due to the airframe design.
However at the risk of ejection into the Electric Flying (where we are politely asked "Please place your electric type Models here." ;)), how about some info on the motivator part?

Adam and Jamie need to hear about this model!
Very nice work.

ABSOLUTELY OUTSTANDING DESIGN WORK, DENNIS!!!!!!!!!!!!!!!!!!!!!! And remember, REAL men wear pink! I surely hope and pray you can make it to the FCM with this bird.

Rumor has it that the Mythbuster will be in Muncie tomorrow. Not sure if he plans to fly in the Mt Comfort Airshow, but with all those stripes, maybe he was going to the MEE Zoo. LL~
Hope to have the lap time tamed down tomorrow and then it's look out stunt world. Hope to get some in-flight data as well.
This airplane broke a lot of molds. "I" beam High Aspect ratio "V" tailed EP airframe that Uncle Dennis built and it don't weigh 48 ounces!! LL~ THE CURSE IS OVER!!!
See you in the morning!!

RAD!
Cant say much more than that.
Hats off to you on your design and I cant wait to hear more about the flying.

Ed
Hi Ed
I used a 1/4 x 1/2 LE, and a 1/2 x 1/2 TE. Flaps are thin (1/4") with a progressive taper rather than a simple "wedge" shape. The I-Beam is normal construction.
My first V-tails were semi scale designs. In practice I determined there were aerodynamic advantages too - but aero risks had to be properly addressed - there are no free lunches!
-
Dennis, you have received a lot of great comments about your new bird. I loved the color scheme until I seen the bottom shot. The pictures makes the plane look like it is moving. Fantastic looking bird and hope to see it in person some time. Wait til Dave Tribel sees this. DOC Holliday
-
Dennis,
It is really great to see an airplane that has sleek aerodynamic lines as opposed to the many pipe airplanes and other current designs. Most of today's airplanes look like fat stubby pregnant whales with absolutely no addressing of how an airplane looks going through the maneuvers.
Only one thing: You will have spray some caster oil perfume on the airplane to make it an authentic stunter!
-
Dennis;
Beautiful airplane. I like longish aspect ratio ships. The V-tail is the added fascination. And, of course, it is electric.
I am also going to Brodak, and it will be nice to meet you . javascript:void(0);

I think that it's cool that the srtipes on Dennis' bird made their debut 65 years to the day that they were used for the first time.......
-
Dennis,
Very well done!!
I really like the out-of-the-box thinking. Purpose built is the way to go. No one will mistake this for someone elses model. Congratulations on boldly going....!!
Kim.
-
If you guys like the way it looks, wait until you see it fly. Many words would describe it, but effortless sums all of them up. It is absolutely silent in the air. The loudest noise is the prop tip cavitation in the corners. I think the wheels are louder than the airframe. Quite awesome!!! CLP** (PE**)
Had great time flying today. We flew from 10:30 to 4:30. Weather was perfect!! Look out stunt world, the bugs are worked out of the Mythbuster.
Take care,
-
Good to hear it went well. I was going to ask.
-
y1 Dennis that is just "to Cool for Words" to describe! Ya know. Columbus isn't far from Detroit, and we have a fall contest. Invite the rest of motorless city, er jobless, and God Bless! I flew Bobbys Stiletto after the last team trials.
Hands down sold me on electrics. Castor blasters for now. Im flying my fathers Airaconda from 1968, originally an I beamer, He made a D Tube of this one. Strangely enough it was sold at the Columbus meet in 68. We are originally from the Dayton area. Never imagined living here 30 years later.
I saw Bob Cravens father not to long ago and I also see Mike Couts every now and then. The last I heard Cravens was flying a desk, F15 command I think .... and Couts bought a sail plane. Bob Sr. still has Jrs version of your airplane from 73 up in Marion, Ohio.
I just put Dad in an assisted living home near me so will campaign this version for him this year. Awesome, awesome bird you got there Dennis, cant wait to see it person!

Hi Dennis,
EVOLUTIONARY....FANTASTIC...COLORFUL...AERODYNAMIC...BEAUTIFUL...and best of all "ITS ELECTRIC"
pretty much sums it up.
A special thanks for the kind comments in your lead regarding some model building "sharing" that took place almost 50 years ago. I remember it, like it just happened yesterday "Time flys" when you're shared so many fantastic memories with great friends for this many years....

Denny,
Whoooo! Subtle color scheme. Can hardly tell it's there.

p.s. very cool. Just curious. Is the tow plane electric, too?

:D A true work of art ;) Best of luck. This could be the one to kick of an electric revolution.

**********************************************************
I just had to throw this in here - got to fly with Mike Ditrick over the weekend at an EAA open house and he showed up with this neat Princess. I told him I needed a picture to help us prove real men fly pink airplanes - he just kept mumbling something about building it for his granddaughter.

Hi Dennis,
Like the german guy on the "Laugh-In" TV show used to say "Veeeeryy Interesssting"
Whats to say? - It's Well Conceived and Well Executed with a huge dollop of trademark Dennis "A" style.
The pink is a shock to stunt guy senses but the Reno racer motif makes it work. What's to say?
Well Done!!!! - Bravo!!! -Jolly Good Show!!! and Attaboy!!! (PE**) (051) CLP** HH%% j1 o2oP CLP** (PE**) BW@
I am going up to Brodaks for the first time as a spectator and hope to see you there.

I don't know which is prettier, the bare wood or the paint scheme. H^^ It looks like Brodak's will have a good electric showing and I CAN'T wait to see the new bird in person!
Congrats, Mike
-
Wow thank you everyone.
BTW got an offline question about finish - it is Moneycote
Flying session #2 in the books - really getting closer. Completely flyable but with the hardest 2% of trimming left to do; added a slug of tip weight, tweaked the tab, moved the battery, still finnessing the leadout position... that sort of thing. The battery has room to move about 3" fore/aft in 1/4" increments, that is handy as I moved it forward some. Low drag target seems to have been met. For comparisons Bob Branch told me he is flying his new electric Nobler with the 11x5.5 APC prop at 9600 RPM for 5.3 second laps (63' lines) I am flying 5.2 sec laps at 9200 RPM with same prop & line length. That is also below the RPM the spreadsheets predicted.
Brad/Elwyn. I'm sorry but definitely NOT Mr. Hyde stiripes; As any fashion designer will tell you, skinny spanwise stripes make an airplane look fat, but bold chordwise stripes make it look long legged. Like Ty's favorite pole dancer... b1
John S: The Columbus meet is on the "want list" again this year, hope to see you. 010!
BTW, in the opening post I mentioned a few people who taught us how to fly stunt. Rick Sawicki was THE MAN; he and his father Marion were immensely helpful to us when we started flying stunt, and especially when we started flying Carrier. Lately Rick has been among the E-Flite pioneers, RC & CL. H^^
Dalton: thanks for the pix of Mike's "Princess". As Will Hinton pointed out REAL MEN can fly pink airplanes. If anyone doesn't like that I'll hit them with my purse! n~
Ted - yup, like those invisible airplanes, don't want anyone to know its ME! BTW, we need to talk about Trivial Pursuit the (electric) COMEBACK Edition! (what??? when the sun shines WHERE???) :-[
Mike P: They fleet for the Fly -In is all electric. HAS TO BE, there's a guy out east with a REALLY good electric Mustang... 8)

Hey my buddy Dennis....I thought I had the market cornered on pink. Makes me look like an amateur!
I have discovered something interesting about cooling the battery. I have a large scoop, and it DOES cool the battery. I have the data recorder in the plane at times, and I monitor the battery temp. I put the probe where I think is the most sheltered from the cooling air. What I found was that the battery is barely getting to 100 degrees F in flight. As soon as it lands and there is no cooling air, it jumps to 120 degrees rather quickly. For me, I think the jury is still out regarding how big a scoop one needs. I have seen some who enclose the battery in a section that has no air flow through it. That makes me nervous.
Any way, great looking ship, and nice colors!
Will we see it at the Nats this year????????
-
Dennis,
I like it!
It looks like the angle of the dihedral is less than 30 degrees. If this is so, what is the reason that you have changed from your norm.
Keith McCrary
-
Hi Paul, Thanks for the kind words. Enjoyed (with some pained chagrin) reading about your ECL experiences over on SSW.
AGREE the chin scoop can do a good job for the battery and ESC. Unfortunately my biggest problem has been motor cooling - including burning one up last year. Have not found a really good way to cool the motor with a traditional chin scoop. The radial scoop on this bird appears to be working very well - but time will tell.
Keith: Thank you for the compliment. You are right, I always used to use 30 degrees. I could fabricate some really surealistic reason for flattening the stab, but the real reason is... "just cuz" ;D
-
Dennis,
I didn't notice what motor you were using, and the battery type and size.
How about the wing area and the all up flying weight.
Can you share that info with us???
Thanks
-
Would one or more of you electric guys care to comment on how you hold the battery in place that still allows adjustment yet lets cooling air get to it.
Thanks,
Paul

BTW, for anyone who MIGHT be contemplating an electric set-up, there is a "sticky" note in the Electric Forum called "List Your Set-up". There you will find several set-ups that people have tried or are flying in birds as diverse as a Barnstormer to an Impact-E (1st generation???) to Will Moore's twin. Here's a copy of the Mythbuster specs:
* 63" span, 567 squares, I-Beam, 15% airfoil.
* Fuselage is stringered behind wing, 47" nose to tail
* 44 oz
* Originally Rimfire 35-36-1200, switched to Turnigy SK 35-42-1000 for nose weight and better match of kV to lower RPM required
* 4Sx2500 Evo-lite battery
* Castle Phoenix 35 in CL "Set RPM" mode
* Will Hubin FM-4 timer with remote switch
* 63' (eyelet to eyelet) lines
* Test flown with 10x5 APC-E prop at 10,900 rpm; 5.0 sec laps, 1840 mah used
* Switched to 11x5.5 APC-E prop, 9200 RPM, 5.2 sec lap time, about 1850-1950 mah (avg.)
Could there be a 12x6P in the foreseeable future??? ??? 8)
Here's some pix of the battery tray. Basically the platform built into the nose has a series of 1/8" holes on 1/4" spacing. The battery sets on a carriage with several 1/8" dowels on 1/2" spacing. Depending on where the carriage sits a minimum of 4 dowels are retaining the tray. no matter where the battery sits at least 2 velcro straps hold the battery onto the carriage and pinned into the tray in the fuselage.
Airflow enters at the front of the battery compartment and flows out the back, the position of the battery does not really make a difference.
-
What holds the battery to the battery carriage?
Paul
-
The straps run under the platform (built into the fuse) and over the battery - the carriage is sandwiched in-between. Fore & aft uprights on the carriage keep the battery from shifting those directions.
-
And side-to-side is constrained by the fuselage sides?
Paul
-
Not quite, the strap pulls the battery into the o'b side and the floor. the battery comparpment will take 4Sx3000's if I needed them.
-
That is quite some engineering. I still love the looks and the color. DOC Holliday
-
Dennis,
I could not possibly add a thing to all the positive feedback your new plane has generated. It truly is impressive.
Once in a while I see stuff on Stunt Hanger that really impresses me and your new ship seems to be at the top of my list right now.
All these new power options make for exciting times and all the more reason for me to stay away. I would never be able to sleep.
Congratulations and Best of Luck.
Les McDonald
-
Just think Les, you would never have to worry about touching the needle valve again. I bet you could still teach the kids a thing or two. DOC Holliday
-
Doc,
That's the problem, I would have to touch something.
If I made a suggestion to one of the "Kids" now days they would look at me like I came from the nineteen seventies.
I wouldn't even take my own advice!
Les McDonald
-
Les,
We have the same problem with Don Shultz out here. We've been needling him to fly for a couple of years. He finally did and although he put the plane in ultimately, I was amazed. Guy hadn't picked up a handle in years and goes out and flies really well. Mechanical failure got him, not the flying. Shultzie has still got it.
-
Maybe seeing the Avenger back in the air will motivate him?
-
You really nailed this one Dennis. Design , paint and power all delivered in traditional thinking out of the box Adamisin.
I wish I would have thought of it first. y1
-
Dennis tell us how bad a 41 oz plane flys in the wind. S?P
-
Hi Robert. I'm not Dennis but I've flown light planes in the wind. Dennis' MB has all of the "bad in the wind" stuff rolled into one. It has a high AR wing and a light wing loading yet it managed to get through the windy conditions. I will say that technique in the wind is at least as important as aerodynamics.
-
Just got back from a week at Brodak & Father's Day with the In-Laws; time for some updates here.
Les: Thank you for the kind words. Somehow while talking about I-Beams in the first opening post of this thread, I completely forgot to mention that the most beautiful I-Beam I ever remember seeing was your first I-Beam Stilletto in... 1979? I am really tickled that this, my first new design since I started flying again, appears to fly very well. From the test flight it felt as comfortable as an old pair of shoes, trimming has been pretty straight forward.
Frank: Thank you too. I think it is also time for you to bring out a new "Miss Detroit"..! y1 8)
Sparky: this is the lightest airplane I have ever built, it flew just fine in the wind. Lower weight means lower "wind-up" energy for the governor to deal with.
Flew the MB at Brodak, and it seemed to garner a lot of attention and a lot of pictures - thanks to all. After about a dozen flights it seems to be doing just fine.
* The bird is light, yet it did not seem happy flying slow. I added some side area via a subfin and problem solved. The new fin don't look bad either!
* I was flying with the battery forward for CG. I went to the next larger motor - 1 oz heavier - and moved the battery full aft again. An un-expected benefit is that it appears that the larger motor is working less hard to deliver the same RPM and thus is using less battery currrent.
Flew round 1 at Brodaks in a dead calm, flew round 2 in some of the worst wind and turbulence I have seen. MB did just fine. Lighter birds will not wind up in the wind like heavy ones will, light birds with governors on them scarcely wind up at all. As Dave pointed out - wind flying is mostly technique anyway.
As it stands Brodak was my NATs, Team Trials, and probably most all of my local contests for this season. I have been out of work since April - now I have to hunker down and replace my JOB!
-
Sparky: this is the lightest airplane I have ever built, it flew just fine in the wind. Lower weight means lower "wind-up" energy for the governor to deal with.
I knew that! y1
-
Dennis,
Thanks for the report.
-
Dennis had outstanding flights with the Mythbuster at the Brodak Fly-In! On the last round, on Saturday, the west wind was picking up and gusty and creating significant turbulence from the trees on the east side of the Expert circle. Windy was up just before Dennis -- and was forced to bail out of the pattern with his .72 RoJett-powered beauty. Dennis was next and flew a 510-point pattern!
I'll attach a pix of it in flight at Brodaks.
-
Saw you flying in round 2 Dennis. I didn't get to see you fly much, since I had to fly in that wind. I was watching him fly on the paved circle one day, and that circle has some swirly air, and he did a half a lap inverted on the outside square trying to find the wind. Archie gave him a lap time, and I'm used to yelling it out, he just talked in a normal voice and said 5.3 Dennis.
It does look like the plane flies really well, and it presents nice in the air.
