Allright! Thanks again for everyone's help. I did a little snooping around the BNF P-51 manual and it led me to some new procedures that worked. I installed the battery in the Sukhoi, then held the trainer switch on the transmitter and turned the transmitter on. It binded right up! The Sukhoi is a bit pitchy, but fun. I would definately advise anyone to utilize a tranmitter with dual rates because in flight it's quite sensitive. It will snap roll when you pull too hard as well. A lot of fun though! Thanks again for the help. The RC community is the best.
