RE: LT-40 and 4*60 Kit Bash
The DLE20 would fit, but I'm not sure it's enough motor to hover this bird at this altitude.
The DLE30 would certainly hover it, but the footprint is just a snerch too wide.
I'm not worried about the weight. I've calculated my wing area at 1060 sq. in. and a projected flying weight of under 9lbs. Wing loading should be around 19 - 20oz per foot. [sm=lol.gif]
