kevin4hsrmc.........i agree 110%....ive allso flown gliders and had no problem at all.but those surfaces are what 1/2inch maby 1inch at the most.i dont know about you but ive had ff with 5 inch ails...
not to mention the elevators.the only reason i say this is becuse i lost one plane becouse of it so if i save one other plane it will be worth it.
good luck
