ive flown my calypso glider before but I switched out the receiver for a flysky one today to go with my new radio. Whenever I bind it the shudders khudder and can't be controlled. Any ideas as to what the issue is?
Shudders without control? If you haven't plugged the servo in backwards, it sounds like it's stripped
The stock Calypso servos aren't high end -- getting stripped when you least expect it happen.
For a sanity check, try another channel on the RX but if that doesn't work, it's time for a new 9g servo. I've got a HXT900 that's happily run my elevator since the stock servo stropped a few years back.
