I recently purchased a Rotofly Ex. It arrived with a bad solder joint on the tail motor an easy fix. I started fine all controls worked model lifted off easily first couple of times. It now will not respond to the controls at all. Fresh batteries in copter and TX. Servos glitch when connecting battery and thats all. I did all the pre flight read the book checked and double checked everything. What do I do now? Any issues with this model any advice or tips mods are appreciated. Thanks Crash

I think I would be checking into the warranty.
