Bought a smartplane by dynam about 2 wks ago , i had no trouble with assembly but i am so frustrated with trying too get the trx which is the fs-th9x too power up plane. On the receiver i have chan 1 as alerons chan2 throttle chan3 rudder chan 4 as elevator. Every thing works but no throttle, once plane is bound is there something that i could have done to unbind it, since me being a beginner i,m sure it,s a simple fix. Anybody,s help gets a shout out from me . Thanks supercub.
