Peter,

i just called up the german distibution for China Models. The guy said that they flew and tested this EXTRA only with .91 FS and didnt need much weight to balance it at the suggest CG. They have NO experience with the much more heavy 1.20 FS motor, they even say that the 1.20 FS is not suitable for this plane. In case the customer choses a 1.20 FS he has to find the right CG by test flying. Great Info!
