Joe, I have every intention of moving to the sun when I retire! On the brite side I spent today at the Museum of Flight in Seattle with my wife and son. Sounds crazy but I had never been there

D_Fast, I use 2 magnets, but that is a good idea. Would be easier than recessing the magnet into the hatch.

Stevercflyer, I built this from a 3 view and scaled it with Tile Print. I suppose I could put it on paper if it turns out to be a good flier.

A10 Twin 50mm, Lessons learned

I know its been some time since I posted on this but here's the update. On the maiden flight I never got the A10 in the air, bad hand launch and broke the front off the fuse. That being repaired I took her out today for its second flight. Had a great launch and the plane took off. Right away I noticed she was very unstable on roll. Once up on step those little 50's really moved out, unfortunately it had NO slow speed ability. If I backed off at all it started to drop like a rock. I fought it around the pattern twice. Unable to slow her down I was coming in hot, just wanted to get her on the ground. About 2 feet off the deck I gunned it to try a go around. As soon as I hit the throttle she nosed down and went in. Sorry I have no video. Here are the changes that will need to be made if I build another one.

1. Lighten the aircraft. Even know I had enough thrust lighter would have been better.
2. Increase the wing area by about 20%. Off of scale 3 views, wing loading at this size was to high.
3. Decrease aileron width and increase elevator width.
4. Decrease aileron throws and increase expo.

Well it was a cool build, I am glad I didn't get carried away with finish and detail

Thanks Joe, To add insult to injury I augured it in at our club fly in today, in front of an audience. It had some design flaws, but lessons learned for the next one. Now I have a couple of perfectly good 50mm's. I wonder where I could find some plans for 50mm jets Greg
