I have just finished making the X 4REDAVE Edge 540 airworthy again...it turned out ok.....anyhow the plane came out all up to 15 Lbs it has a ZDZ 40 with a Menz 20X8 ..firstly do you think this enough motor/prop and secondly where do we think the C.G should be??? The wing inc the aileron is around 10" wide at the tip.....shall I assume that around 1/3 from the leading edge which is around 3.3" is a good safe place to start??? answers on a post card please no.... if any body has any clue's they would be greatly received....I am hoping to madien it tommorrow thanks guy's Colin.

i would check rougly 1/3 of the fuse length. this should be very close to the wing tube. if the wing tube is close to the high point of the wing rib id try it right their or between the high point and the tube. real nasty things happen tail heavy with the engine out not so bad as long as it stays running. same old rule of thumb applies better nose heavy than extremly tail heavy.
