KR> CG 2 vs 2S

2014-07-08 Thread jon kimmel
You are correct that the new airfoil can change the cg limits...the aft cg
limit is based on the wing...not the aircraft...so a different airfoil
might affect the c.g. range.  I looked through a selection of different
aircraft and 15%-35% mac is a pretty common range.

Where is the center of lift on the new airfoil compared to the RAF48 
and won't that determine where the CG should be located?  Just asking.
