View Full Version : Glitching, Trex 450 SE + Spektrum. HELP !!!

I've got a good one for ya'll .... Got Horizon Hobby stumped at this point. Sure am hoping to get some help here. First of all here is the setup...

-Trex 450 SE ( with superframes )
-GY401 gyro
-HS56 Servos
-Stock blue 3550kv motor
-DX6 radio ( not DX6i )
-AR6000 receiver
-TP2100 battery

We are having trouble with one of the servos hooked up to the swash jumping. It seemed to be the left front one so plugged the right front one into the left front channel. Did the same thing. Plugged in a new servo ( HS56 servos by the way ) did the same thing. Hooked it up with a JR7202 radio and BERG 72mhz autoshift rx. Worked fine, no problems. Bought a new AR6000 RX and hooked it up, just left it hanging out for testing, did not install it into the frame. Back servo jumped now. Moved the AR6000 over a little bit and now the left front servo jumped. We are just running it up to almost lift off, but it does it in a hover too. Quite interesting flying !!! Then we hooked up my DX7 TX and had the same problem. Then hooked up a new AR6100 rx and still had the problem. So we have tried 3 rx and 2 tx with the same results. Are we getting static buildup on the belt, do we have a bad motor, bad esc.............??? We are stumped.............why does it work well on the JR 7202 setup? Thanks in advance for your help!!!

easy solution, spray a light silicone based lubricant on your belt, this should stop the servo chatter caused by this static. typically you dont get servo chatter w/ 2.4ghz systems because of the band being so high, but it has happened before. so try that, if you're still having the same problem i would contact horizon hobbies to see if there is a problem w/ the radio itself.

Hummm. sounds like your getting a spike from your ESC. hook a volt meter to plug that plugs into the RX and monitor the output voltage from the ESC.

yeah, I'd suspect the ESC too. What is it? tried a filter on the throttle lead? If you have another working one to swap, could eliminate or identify that. Spraying the belt as mentioned already is easy.
