RE: Sun Fli 5
One thing about the Sun Fly series.....
Make sure to build the stab like the original KAOS to avoid flutter.
The solid sheet stab used on some versions of the SF are simply not strong enough to avoid flutter.
I'm not talking about elevator flutter....the stab is torsionally weak which will allow twisting and will quickly start destructive oscillation.
This would happen even with the low powered baffle piston engines of the day....but today's Rossi would definately be a lot of fun!!
