Thanks for the answer Fred

I don't have problems with my landing gear but I reinforced it with some light glass fiber from the inside and for the stab I used some carbon rods I had from a FF glider, but I'm looking for a mod that gives me better harrier performance, something to eliminate the wingrock, the ail/elev mix works but I want to know if there is something better to improve the harrier

Hope someone has found something that works
Thanks again
Sergio
