NOTE FROM GGRN

Precisions about the flyware 220 i used. It's a 220 12, 2300 kv with a GWS 4 x 2,5 in the beginning. But even if this prop allows low amps consomption, it was not fully adapted. Graupner Camprop 4,7x4,7 is the right prop, but it requires to take care of torque during launches or wave-off..This parkjet was designed for this motor, so it's difficult for me to recommand an other solution now. Even if this Skyhawk is not difficult to fly, she's not for Rookies...So, i imagine experienced modellers'll find their own solutions. Bob(rvincent) is going to use a Littlescreamer... It seems to be a good performing solution...Just a remark : Motor far away back CG requires to pay attention to motors' weight...
