Hi,
A comment wrt the flying qualities of this Hellcat model:
Do not let your model's cg be aft of value specified in the manual-it is very sensitive in pitch and an aft cg just leads to big trouble! Also, heed the throws called out.
The Great Planes AccuThrow Deflection Meter is extremely valuable in both zeroing and measuring throws on all surfaces-which btw are not flat surfaces.
On my OS 1.08 the Hellcat goes like a scalded ape!!
