Probably my own fault, I haven't done the dual aileron mod, or the tail-dragger yet, but I did take out the dihedral & used britbrats suggestions of the tuned pipe, & the 2 3/4 in spinner. Just those few mods there turned it into quite the little hot-rod & I've been shredding it pretty hard ever since. With the single aileron servo it's no wonder I fluttered it out, probably stripped some gears in the servo too for that matter. But hey it's a Trainer, I'm supposed to abuse it right? Now I'm shredding it up with the Tower & it's amazingly aerobatic, allways nice to have a spare Trainer to throw around the sky! My budddy keeps egging me on to break out my low wing planes, but I've been having too much fun abusing these Trainers, I did maiden my Drgon Lady but I still like throwing these Trainers around because I can get just as bold as I want to with them & if I plant one, so what? I got more.
