I will try them out next week when I got some more time, Ill do some further research about them until then. Thanks for the tip.
I think the dihedrals are the factor most fighting against the ailerons, and when less air is flowing on the ailerons on slower speeds, vortex generators or not, they are bound to lose the fight against those dihedral wingtips.
But I like experimenting, I will see what they can do to increase the aileron effectiveness.
As for the inverted, I dont really plan on doing much of that anyway Its like trying to ride on a cushion of air. Same thing with any plane with dihedral I got. I like the other aspects these wingtips offer so I dont feel like cutting them down to improve inverted performance.
I will definitely post on the RCG F&L thread when I got the time, but I want to make a proper entry, so I need to find some time to write... I dont have enough tonight
