In reguards to a basic semisymetrical wing as on the H-9 p-40 warhawk. Does anyone know if it's safe to balance at the 33% rule (spar). I have one of these and with a chord of 14.25" at the fuse 33% will get you about 4.7" from the le at the root. The MFG recomends 3" wich makes for a very nose heavy plane that will not even taxi w/o nosing over. can any one advise.
