My Latest Project
Here's my latest project. I scaled down my 1/2A Stick plans to 24" and slapped a cowl and landing gear on it. I am powering it with a Johnson 250 and a 1500 mAh 2 cell Li-Poly pack which produces about the power of a PeeWee .020. Right now it weighs 8.5 oz without the RX and covering. I could save 3 oz if I switched to a TeeDee .020.

All covered and ready to go. Ready to fly weight is 10.2oz. A little heavier than I would like, but when the battery and motor weigh 4.6oz you're not left with much to work with.

RE: My Latest Project
Bipe, thats about the size I scaled mine to (actually mine was 21" ws) for my TD 020. It was 7.5 ounces I think, and has the glide of an overweight wingless pidgeon.... Allthough on grass it doesnt matter, I just bring it in at a steep angle and try and flare at the end. I hope you land it while having some juice left!
Did the package arrive?

RE: My Latest Project
Yes the package arrived, thanks. Now I can get my PeeWees running.
I was thinking of wing loading when I scaled it down so I made the chord 5" instead of 4.6", which it what it would have been had I scaled the plans exactly.
It was only raining a little today so I decided to brave the elements and give it a try. It flies, but only just. It will roll and fly inverted and can loop from a dive.
I had already converted a free flight plane (picture attached) which flies fine on the same power system with a 32" span and weighs 12.4oz, so I thought this would be a little more aerobatic. Unfortunately the wing loading is just too high. Still, it flies better than many electrics that I've seen.
On to plan B.
The motor spins a 4 3/8" prop with about 1.5 pitch at 15000. I can save 3+ oz by going to a TeeDee .020 which spins a slightly larger prop with a lot more authority.

I switched the battery to an 830 mAh pack and replaced the Hobbico prop with a Cox 4.5X2 and it flies way better. It will now do an outside loop and glides much better deadstick. The flight time is cut to about 9.5 mins wide open, but that's fine.
