I bought a vtx10 brand new from A main hobbies and love it, have it in a SC10 running a 17.5 with a Airtronics radio. I put a deans on it, calibrated the radio and have been running near the front at my local track ever since. I Was super excited when I got a good deal on a used VTX10R with a 13.5 motor but I cant get it to work. Have futaba 3pm radio I am trying to bind to, I have steering but the esc beeps initially when I turn esc on and then after a few seconds beeps constantly and the lights on the on off button blink and no throttle. I tried hooking up the proguage and changing profiles, checked the epas, saw on earlier post about checking the abs function so I will check that later. I Attempted the new radio calibration set up but nothing is working.It's the same 10.5 motor and radio gear that was working with the havoc it replaced. Anybody got any ideas on whats going on?
