I don't know about you guys, but I've found that if it's real windy (like a day when no one else is flying) and I try to take off my SPAD3DTH into the wind like the normal plane it can get real squirrely during roll and lift off, actually had it blow over right after lift off a few times onto it's back, so with alot of crazy looks from the old timers (just watching,not flying) I took off with the wind (15-20 mph) and it is much more stable both rolling and lifting off. Might want to try that. Never really had a problem on calmer days.
