An electric Legacy 40. The build thread is in the electric section.

I'm building my first ARF. It's a pain in the ass too, the wing seat is so crooked it would've looked like an X-wing. The bellcrank screws and washers were corroded. Y'all know the other stuff. I shouldn't have expected to just throw it together.
I'm going to replenish my 1/2A fleet with a couple of good old tough Stuntman23s, and a Junior something for either my Tee Dee .09 or my TT .15. I've drawn a profile of a Cox Hyper Viper and I'm thinking that'll be a nice Jr sized plane, It's a cool looking ship, but I don't think I can make the nose as long as the plastic model
That work ought to go well into the Spring assuming I don't wreck a stunter. I hate when that happens.
And I have some plans from Bob Zambelli for Muciano models on the back burner. A red Hot Angel will be the first of those. That might be summer or next winter. I'm an awfully slow builder.

I've started a Jr. Flite Streak (Brodak) for e-power. While the wing is in progress, I'm doing some "virtual building" to fit the electronics into a somewhat cleaner package.
Motor: Turnigy Aerodrive SK3 - 2836-1500
ESC: Castle Talon 35
Timer: Hubin FM-9
Using SolidWorks CAD, I can plot out the parts, find the interferences and figure out what needs to be hogged out before actually cutting wood.
-
Keith, I'd like to learn to use a program like that. How tedious is it for a beginner to draw the parts and properly scale them? I have 25 years on PC computers, just new at software like CAD. Is there freeware available that you would consider useful?

Hi Rusty -
Unfortunately SolidWorks isn't a freeware tool - it's rather costly. Its advantage is that, once a part or assembly is created, it can be printed / plotted from any viewpoint. All views are linked to the solid model. The 2D cad programs require the drafter to actually draw separate views from, say, both top and side views, and those view's aren't necessarily linked. SolidWorks is a very intuitive tool and didn't take "long" to learn (maybe a hundred hours) before I could quickly model parts. All parts are true to scale, at least as well as my micrometer can measure. Call it a second hobby :-\
Honestly, I've not tried any of the freeware that's out there. Microsoft Visio is my choice for 2D drawings.
-
...I haven't graduated from a No. 2 pencil and T-square HB~>. Awesome stuff Keith!
-
Thanks Keith. Anything you're good at on a computer almost has to be a sort of hobby. I'm trying to convince my Mom to just explore and click and read her new laptop.
Thanks for the reply. I've spent way more than a hundred hours test shaping and fitting and cursing.

Rusty,
I don't think there are any free 3D parametric CAD programs out there (at least legal ones). The one I would suggest is Cubify Design http://cubify.com/en/Products/Design It's $199 and it has a free 14 day trial if you want to give it a try. It's a slightly dumbed down version of Alibre Design which is what I use. By the way, in 3D CAD you design everything in full scale in whatever units you want. When you print the drawing thats when you select what scale you would like to print at. I even use it to determine the C of G before cutting anything.

Thanks Paul. I wonder if my old Win7-32, dual core Pentium would choke on a 3D program like that.

I'll usually determine that by just looking at the part in front of me. D>K

Hey Wayne, I am working on something. I'll post when it's a bit further down the line.

And I'll likewise continue to do the same. It was just a thought, a magic airplane building assistant. But it's out of my league, concentration-wise and processing power-wise... not to mention pricewise.
But thanks guys, for making the effort to reply to my question.

I'm putting the P-40 thing on the back burner now again for a bit. Next in line is painting an Old Timer that's very close to ready. Probably paint the P-40 right behind it. :)

No building season over here, but I've been working on this Spectre (Yves Fernandez design) for an Enya SS45S. It's moved on a bit from the photo, and is about halfway painted now. Going very slowly though due to work.
-
Well the old slow DOC is finishing a Chupim20, starting a Lil Quickie, cutting parts for a Hobo and looking at the Fury .15 carrier kit I brought home from Brodaks. Other wise I'm spending too much time on the computer according to the misses.

A new project for me is an OTS Viking to use with Super Cyclone .60 on spark ignition. Hoping for it to be my contest machine for Huntersville in May!

Actually, it probably is. I was challenged to put my old Fox 59 on a junker acoustic way back when because I had said you could fly anything control line with a big enough engine!

Rusty,
I don't think there are any free 3D parametric CAD programs out there (at least legal ones).
There are quite a few really good starts, many of which will let you make parts that can be 3D printed. None (to my knowledge) deal with assemblies yet, and all are clunky.
I'm using FreeCad, mostly to make pretty pictures to show clients so they can say "Eww! That's not what I wanted!". http://www.freecadweb.org/ (http://www.freecadweb.org/). I still need to figure out the "parametric" part.

The Tutor II ARF is almost done, TwistStang gathering dust, and a bunch of shop time used to build. Honda D-16Z6 SOHC Turbo motor with my son for his Civic Hatchback. Goes against my GM BowTie heritage, but have to admit the engineering and machine work in these little beasts is impressive!

Hey Jim, that LG on top is finally the perfect cure for the Fox Burp! I gotta get me some of those.
I tend to get caught short on fuel doing whifferdills after I finish the pattern. They'd come in handy for that too. LL~

Jim, how about leadouts on both wingtips now? You can end up with a "Universal Ringmaster" ...

I am converting the anemic Cox Hyper Viper to electric and while I'm at also converting a SIG 1/2 A Skyray to electric.
both will be 3S powered, 6amp ESC's, Brodak Simple Timer's, and Twisted Hobby's crack series motors. The Hyper Viper will have a few more KV's than the skyray though.

Now that's a great idea, even better than converting it to a Tee Dee, which it should have been in the first place. I don't think Cox used a TD for a single product engine. Building a Tee Dee .09 or .15 sized profile Hyper Viper has been one of my back Burner projects for years.

I have too many projects on the plate.
1) I have stripped the "Galloping Commedian" that I built for the OTS 25th anniversary at the GSCB. I am starting to make repairs before refinishing.
2) I have a "Dmeco Continental" about 3/4 built. Without the turtle deck it looks like a small Stunt Wagon. I wanted to built this airplane when I was in grammar school. Kitted in 1955 it is OTS technology in the Classic era. It will never be a competitive Classic but it should be a fun airplane. It will have an early Fox .25 in the nose.
3) A new design for Pampa events. It will be electric and will looks like a midget air racer. 605 sq inches
4) A new electric design for Pampa events. 620 Sq inches. It will look like a late WWII and Korean fighter. Retracts are planned.
5) A Classic "Falcon Jet". This is a never completed project design by John D"Ottavio. The fuselage has unbelievable contours and a tricycle gear. I have obtained the original airplane from John to use as a template. The wing and tail surfaces are standard Falcon.
6) I also have a new bipe on the drawing board that will do anything that another bipe that I published in FM a while back and now is a widely flown kit will do. The new bipe will be called "Vagabond". It uses the "Hobo" airfoil. It will be fullbodied with an inverted engine with cabane struts and N-struts and will look more like a real airplane with "Pitts Sampson" influence.
Whew! In addition I do custom vinyl grapics and masks.

L.O.L.!! Yeah man! I figure the burp is a warning for the judges!! Just imagine my score during an Old Time Stunt meet ..... take off one way .... land another .... judges would have to take my word for it during inverted flight!! r.o.t.f.l. LL~

Great mind must think alike!! I thought about that but at my age it's gonna' be a heck of a job to run to race out to grab the two handles then fly with the plane in a constant knife edge!! #^ Sorta' be like flying a great big stunt kite but it sure seems like a kool challenge, eh!! :!

Hi Jared,
Way cool thing to do. The H/V would do a fair pattern with a killer bee .049. However, the production engine was used and that killed a pretty good model (for being a plastic C/L Cox model). It always had great looks but disappointing flight performance.
I really considered turning it into electric but the big bug-a-boo was the batteries catching fire and burning the house down and possibly injuring someone. So the owners took that away and said we must use the production .049. The one really bright spot about the H/V was the molded two half wing which for its time was really pretty cool and rather light. I used the same wing with a built up fuse balsa fuse and it flew hands down better over the plastic fuse and the production engine.
Good luck and keep us posted on how it flies,
Mikey
-
Couldn't agree with you more Mike. Took probably Cox's best 1/2a stunter and ruined it with their "sure start .049" It should have come from the factory with the killer bee or TD .049. We put a killer bee in another H/V we have and it helped but it still needs a little more power so since electric have come a long way and I have some electric experience with my R/C stuff I figured it was time to give it a try. Keep ya guys posted, its been 0 or negative temps lately with wind chills so don't know when I'll get to try it out haha.
-
I always liked these threads. It's cool to see what people have going on in their shops. I love the plane with gear on both top and bottom. There is a real fine example of craftsmanship on the model with the stringers on the fuse.
So here is what is on mine.
1. I found this little drone/quad on my work bench. I better watch out I could take down the whole hobby industry with this thing.... It sure is fun to fly and pretty darn maneuverable as well.
2. Assembled a belt drive transmission and mounted a motor.
3. Put all of that and other stuff into a carbon frame and then programmed it on my PC.
4. Boom finished product. SAB Goblin 570.
5. Moved to the other building table, AKA the coffee table, and built up a cool Lego car with my son.
6. More Lego building with my daughter on the coffe...er...indoor building table. The Battle of Helms Deep.
Oh yeah I did build a motor crutch for my PA 75. Not much to see there.
Anyway, thanks for looking. Keep it coming myself and many others always love to see the projects.

Please, step on the drone Doug and get to work on the rest of the PA 75 project. ;)

I made some circuit boards that tell an old person whether the battery in his airplane is charged:

Haha. The little drone is a fun change of pace and something to do around the house when I probably should be doing something else more productive, you know like raking leaves, painting the bathroom, fixing a light in the kitchen, messing with my kids, writing my district 8 column..etc.
But hey when its windy 24/7 for 15 months you have to fly something right?
The helicopters come into play there. It was just a little thing to mess with when I started 1.5 years ago. I had one of those mini ones. But then I learned and traded up and bought and sold a few along the way and got into a couple of large ones that will handle heavy winds. So I can go fly something even when CL is not an option.
I did get to fly last weekend. 2 flights! First time since October. It was so awesome!!!!! I can't wait to go again. But, 16 mph winds with gusts to who knows what today are making that not an option....maybe tomorrow.
-
Howard!! Tube type!! Holy shades of yesteryear, Batman, that brings back some great memories!! ("Course, my new guitar amp is also tube type, but that's not flyable.) The size of those reminds me of the old solder-in 6021's in the tacan!

Will, you are living in the past. Those are light emitting diodes, not valves.

Oops! Yeah, I'm guilty of the LITP thing, happens more and more these days! Look out senility, here I come! (But those 6021's WERE phenominal tubes.)

Maidened both 1/2 A electrics today. The skyray was terrific just as much power as a black widow maybe a touch more. The Hyper Viper also flew with as much power as the killer bee .049 but unfortunately the wing has a warp in it so it wanted to roll into the circle pretty bad. No worries though, I have 2 more H/V kits so for now I just grabbed a wing out of one of the other 2 kits and it looks A okay. So now have to wait for another nice day to give it another go. I'm afraid to say the days of fighting reed valve .049 starting, running backward, quitting mid flight, refueling, messy clean up might be over for me lol. It was, run lines, hook battery up, press start, fly, land, wind lines up, and put plane back in truck. All before my dad had his plane warmed up and fueled ready for his first flight. LL~

OK,
Here are my projects for winter: D>K
1- Brodak Viking which will have a fox .35
2- Brodak ARF superclown which had a warped wing and warped fuselage. I recovered the wing with new plastic after getting the warp out. Had to cut a new fuselage and now have three coats of dope on it. Next is silkspan. Also added a trippler on the front. Will have an OS FP .20 iron piston...
3- Finishing a Brodak ARC cardinal which will have an ENYA SS40
4- Sig Banchee which I moved the wing forward 2 inches. Also added 3/8 inch tripplers to the front. Adjustable tip weight box and leadouts. Finally added 4 inches to the stab elevator and changed the look of the rudder to 2015. Next is silkspan...

This was one of my winter projects. It is a Time Machine 50 that had become a hangar queen. I built it maybe ten years ago or longer, I can't remember for sure. It did not look like this at that time. I have no "before" photos. Just as well since it did not look very good. I have built several of the Time Machines and the 50 flies better than the other two sizes, at least for me. I never liked the jet style look of the original Time Machine so every one I built had a modified fuselage: either a bubble canopy or turtle deck. I understand that Tom Dixon has a Time Machine II version which eliminates the jet style look. Maybe I can take credit for convincing Tom to change the look.
It became a hangar queen because I never could get the Double Star 50 to run well no matter what I tried. And, it had a rather quickie paint job that I never really liked. So, it just sat around, or got kicked around, acquiring hangar rash and dust because I had other projects to finish.
There were a few times the DS 50 ran well enough to show that the plane had performance potential. So, last fall, I decided to get this thing in the air again. I wanted it to look better and to have a reliable engine. I sanded off all the existing color except for the orange, which was part of the original paint job. I re-worked the engine mounts, installed an LA 46, and cut away a portion of the front bulkhead to replaced the 4.5 ounce tank with a 5 ounce tank. I expected a weight increase due to the better finish so I wanted more fuel capacity in case I needed more nitro. The original weighed 52 ounces, now it is 55 ounces. The original also had a "half cowling" and a fully exposed engine. I trashed that cowling and made a new one.
I have had time for only two flights since the re-work. The LA pulled it around just fine but it was a cool day with low humidity. It will not do that well in the summer. But, for those two flights, I was using only 2.5% nitro so more nitro will help. Also, I was flying on 0.018 x 64' lines, eye to eye. Maybe going to 0.015 lines will help a bit or maybe shorten the 0.018 lines.
I started another Time Machine 50. It will not be fully sheeted foam as this one. It will have the foam/cap strip method. Maybe I can take a few ounces off of the new one. I am looking for a different engine for the new plane but if I have to, I will once again use an LA 46.
From a distance, the re-worked plane looks OK. There are surface flaws and dings that I did not address as I wanted to get another plane in the fleet without taking too much time. It was worth the effort. It looks good enough, has a reliable engine, and should have enough performance to compete with it this year.

On that DS 50, sounds like the PL is in backwards. Have you taken it apart and checked it? Or looked in the exhaust? ::)
Good luck, Jerry

Well, now that the SiameseMaster is completed, successfully flown and now just hanging up collecting dust, I've started a new project. Check this out!! Can you guess what it is??

B-29 or B-50

Wow. That's very cool. A real model airplane.

L.O.L.!! Yeah, I just noticed that It showed on the plans!! l.o.l.!! It's a scratchbuilt copy of an old KYO B-29 Superfortress kit that my flying buddy owns. He didn't want to part with the kit but he allowed me to replicate all the parts and I finally got bored and started assembling the thing. Now I have to figure out how I'm going to get my hands on 4 each reliable OS .25 r/c fsr or fx engines (I think I'll feel more comfortable with ball bearing engines). I know I'd like to have a third line for the throttles or maybe rig the throttles for radio control. Either way I need to scrounge some engines from somewhere so I can hopefully get to Brodak's for the first time in my life!! Unfortunately I don't know enough about electrics to rig it and feel comfortable besides I suspect I'd have a heck of a lot more money invested ready to fly versus the glow engines, huh??
Howard, thanks for the kind words! Hopefully it will be worthy!! I've got great ideas but laughable skills!! ;D

I have two of the DS 50s and they both ran the same. Never taken them apart except to take the heads off to add/remove shims. All the DS engines (baffle piston) seem to behave the same: going lean, running away, low on power, etc. A larger venturi cured the DS 40 but the 50 did not respond as well to a larger venturi.

the LA25s are very reliable and run like swiss watches. My next winter project is a profile B-17 that will have 4 Norvel .061s and the throttles will be controled with a 2.5g radio. Itll be allot easier to get servos working together than all of the sub-belcranks needed.
As for me and this winter, the Aeroshell T-6 is still chugging along slowly. Work has been keeping me late alot so progress is slow. Hoping to have the colors on it before I leave for NTC on the 9th.
I always wanted one of the late, great Byron Barker's awesome paint stands. Alas, he is no longer with us so I had to improvise. My building table is a big slab door that I "tactically aquired" from some old barracks being torn down on post. The cutout for the door handle is against the wall. Using that, I built a stand out of PVC that uses that hole to anchor it. I can cut different size legs to raise or lower the stand to suit the needs of the model I'm painting I can also pick it up and swing it out of the way so I can still access my table to start work on the next one :D
