Does any body know the proper CG for the Cermark F16 the Manuel says 6 to 6.5 in from front leading edge? I have friends who have them and say no farther than 4.5 to 5 in from leading edge. What is the proper safe CG, Also how do you program your P70 to have very little spool up lag? they say you can do it in the CPU is this true? Thanks for any help............
