good luck getting nitro planes to help. they don't even take care of there dealers any more so i heard from a friend that is a dealer. i've lost faith and they lost all my business.
we at our field lost one of those yaks last year on maiden also same problem and had to purchase another and re-desinged the horz. stab. as far as nitro planes. no one in our club will do any business with them any more. A GOOD EXPERIENCE IS SHORT LIVED, A BAD ONE IS NEVER FORGOTTEN
