I guess I am confused as CG should not be differant on epower vs fuel ? I understand everyone has there own "sweet spot" and some like more tail heavy vs nose heavy or dead on but CG is CG .
Forward Rake is 100% related to halping advoid nose overs as is how the plane ia balanced but I have never gone out of my way to achive forward rake if it was to dramiticlly change my ability to achieve CG .
Personally I like 25% of Mac as a sweet spot and its never served me wrong .
I can also understand that if you useing glow /gas it may be more difficult to achieve CG vs Epower because of the tank position , but in the end CG is still the same "goal".
As far as the "feel" as Kahlog knows , the Fiberglass on the CMP planes is differant than some other brands but still many have the same flex including ESM . MY ESM Corsair has the same amount of Flex as does my CMP planes . Now I am told that CMP planes have less tolerance to the hot sun , I dont know because I dont allow them long periods of direct sunlight .
I do however reinforce all my glass /composite planes at super flex points on the inside with either FliteSkin or very very light ply .
The differance is incredible and its a simple sand , apply CA and hold , in miniutes your plane feels rock solid with very little weight gain
