You could try for about 1500 rpm lower if you can get away with it
before flight make sure you fuse is well fixed to your mechanics a lot of first flights have ended in uncontrollable vibrations that can kill a fuse in no time.

What dampers have you in the head the softer the better for scale

Hi Alex thanks for the info when you say 1500 rpm is that the maximum for the whole range,and what about the pitch range.The dampers that are fitted are the softer of the 2 pairs that came with the original se 90 kit.
