hey guys. i have the 60 version and recently faced with a big obstacle. I decided to keep the stock retracts(to be used with hitec hs75-bb). Sadly for the second time around, they burned out and has kept me from doing my maiden flight. Been considering the JR791 for replacement. CG still heavy on the tail and measured it at almost 120g to level out(if added to the firewall). Any tips? my first warplane and not too many guys at the field with extensive experience on retracts..<div>thanks</div>
