I got the Firebird Commander 2 for Christmas....so excited! Took it out for what I thought would be a fun day of flying....the engine would not turn off. Still could control left/right rudder, but engine would not turn off or even respond at all to the controller....finally flew so high lost sight of it in the clouds and never saw it again!! So disappointed....emailed Hobbyzone to see what kind of defect would have caused the engine to lock in to full throttle and what kind of refund etc policy they have - only response was they don't cover "flyoffs". I advised I understand "flyoffs", but this was obviously a defect or flaw that would cause the engine to stay in full throttle...still replied they would do nothing about it. Very disappointed...will not be dealing with Hobbyzone again...will be spending my money elsewhere...
