Here's some more interesting info. It will fly ok with a £7.99 BP-21 / 2408-21T bell motor. Not fast but with the usual 8x4 GWS HD the climb rate was pretty good. It's all I had to hand and it it flew very well. More interesting is that I cracked my LE (too easily) and thought that I may as well see if it would fly with the wing from an old Firebird Commander - about 40" and 2/3 of the stock chord. Four rubbber bands looped round the landing gear and it was in the air within a couple or three metres ! I didn't like the rudder only configuration but it did fly ok and the glide in for landing was very smooth and I did two perfect landings before deciding I'd not risk it again with that wing
