I am needing help with the set up on my t-rex 500. I had a mini v-bar on it and a DX7 radio. unfortunately the tranny has failed and I cannot get the program to work on my computer to set up my new DX18 to the v-bar. So I purchased a 3GX mSR as it said it was simple to set up. I have bound it to the radio and have the pitch and the rudder working but when I move the aileron or elevator a small amount the servo will move a small amount and then slowly move to full travel. Is there anyone out there who is able to help me
