KaP - GREAT pics!!!!
Where did you end up on the CG and flight control throws?
I have read further back that 5 1/4" seems to be a good spot on CG. I am at recommended throws both High and Low rate. Tempted to add more flap though... but overcame it.
Expo on high rate ... 30% from some...
Still have to get engine in. The additional cuts for the 4 blade prop were a pain... then balance... took some time.
I am ordering a Tetra bladder type airless fuel cell for the tank at 20oz so I dont have fuel foaming issues. Personal thing really.
