TJ,
I have the 84" version as well, been flying it for a couple of years. They changed the cowl from the three piece to a single piece because of all the complaints they received on the three piece. Mine must have been one of the first because the instructions still refer to a three piece. I'll check the throws for you and get back to you later this afternoon (plane is out in the garage). I'm using a 76 cc twin gas engine and the performance is phenomenal at 20 lbs. I use 20% expo on the controls. I wouldn't worry too much about the control throw - it's a *****cat to fly. It it's not too late I'd suggest adding a 1/4 inch break-away plate to the landing gear. With the kit design a really bad landing can mess up the wing pretty bad.
