Mythbuster! My first true electric design

[Dennis Adamisin]

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?

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.

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

[Les McDonald]

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,

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.

[Mark Scarborough]

Maybe seeing the Avenger back in the air will motivate him?

[frank carlisle]

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.

Dennis tell us how bad a 41 oz plane flys in the wind. 

[Dave Adamisin]

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.

[Dennis Adamisin]

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"..!    

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!

I knew that! 

[Crist Rigotti]

Dennis,
Thanks for the report.

[Will Hubin]

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.

[Matt Colan]

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.
