What is the best shape for the leading edge on the wing of an IMAC sequence plane? Should it be sharp, dull, different from root to tip? The plane will be flown in Advanced and Unlimited.


Thanks

Sharp leading edges help for spins and snap rolls. A lot of planes have such a light wing loading that it's difficult to get them to stall on command if the leading edge is rounded. If you have a specific plane in mind, check out what other flyers have done with the leading edge of that particular plane.

The plane is a 42% TBM Extra 260, and it came with the leading edges getting very sharp towards the tips. I'm just worried about this causing the tips to stall before the root does.

thanks

I wouldn't worry about the sharp leading edge near the tips at all. You can't snap roll a plane without stalling the wing. Your plane will fly so slowly with the nose high that you will be amazed.
