Take the bind plug and make sure its bound.
Check your voltage to the reciever most problems in setup are voltage or binding, ie after putting together a new plane and using a 4.8v pack that was lying around it would not bind due to low voltage, fresh pack fully charged no more problems

Send it back or send it in to JR

Had the same problem, would not bind then it would but the servos went wild, turn it off and on and no servo movement at all , then it would bind , one elv up, one down at full deflection, rudder full right.
there are some bad units out there.

Never had this problem with any other Spectrum 2.4 set up.

Don't waste your time with it send it back!!!!! Do not trust the red 921 unit

Put the 9100 in the same plane , and no problems at all.

He connected with the new cable station and the receiver and is doing the same thing, the battery is a new CN 2400 4.8 and charged flight once and then no longer connects more, I hope if 10 minutes or more if you connect but takes to connect. Thank you for responding

Re: 921


Keep your Radio, call JR or Horizon, tell them about your problem and send just the RX in. if you can ask for an exchange or credit , get the JR-922 or the Spectrum 9100, these are the best money can buy .....

Get the number off the back of the book that came with your radio and call them.
