RE: Super Chipmunk
Maidened today, it flies really well, starts from grass at what feels like half throttle and just sits there until it is picked upp. Rolls are a breeze and the inverted flying is excellent. Made a few large turns over the field inverted and at half throttle, I'm really pleased with this one!
The inverted engine was no problem at all, I just have to change the way I usually fuel. Filling until fuel comes out the exhaust will effective flod the engine...
I used an APC 6.3x4 which spins at about 16500 rpm when maxed out on 10% Nitro (I think I have an extra shim in there too). It ran a little rich on the low end, might add an air bleed to fix that.
I'm still stoked by the performance, just have to finish the cowl now...
