[NSRCA-dist8] FW: Pattern plane

[RICHARD BERGERON]

Hi Karl,

The control throws at 8 degrees and 10 degrees are a good start for the aileron and elevator. The CG at 1/3rd back from the leading edge at the fuse is way to far forward for a start. That would make it too tail heavy which would be a challenge.  Try 45% back from the leading edge and it might need to go more than that after some trim flights. Some of the old pattern planes ended up around 50% to 55% from the leading edge.

Good to hear your flying something. Good luck.

Need to know where to set the CG.  1/3rd back from the leading edge at the fuse?  Good starting point for control throws, 8 degrees on aileron and 10 degrees on elevator?
