I have a 2.4Ghz radio (FlySky FS-GT3C) and I’ve never noticed any issues with it and I’m using it on 3 different cars. But one car (TC6.1) will suddenly go full throttle for a quick second or two after I press the throttle button. It doesn’t happen all the time but often enough that it's caused me to break a few things before I realized what was going on.
So I've fully tested this thing every way I know how and the problem is still there. At first I assumed it was the receiver but now I'm not sure. I think it may be the ESC but I was told by my LHS it's probably not. So here is what I've done so far to try to isolate the problem...
1. I assumed it was the receiver (FlySky), so I took another receiver (same kind FlySky) from another car that doesn't have any problems and I put it into my problem car. Problem started happening. I did this again with a 3rd receiver (Hobbywing but same as FlySky) from a 3rd car that has no issues and the problem started happening again in my problem car. I even put these receivers back into the cars they came from and then tested those cars again and they had no issues whatsoever. So it can't be the receiver.
2. I unplugged the transponder and fan (was told maybe these are causing interference). Problem still happening.
3. LHS thought it could be the servo (Savox SC-1251MG) so we tried connecting a “glitch buster” but the issue still seemed to be there so then we tried a “double cap glitch buster” it seemed it was fixed but the problem is still there.
4. Then I disconnected the servo and the only thing that was connected was the ESC and the problem was still there.
The reason I thought it was the ESC earlier was b/c one of the wires was exposed and I thought maybe there is something not working right. At this point, it has to be either the ESC or receiver and I’ve tested the receiver with 2 others. Is there anything else I’m not thinking of? Can the ESC even cause this kind of a problem? It does control the throttle in the first place but would it create glitching? I’m totally frustrated and dumbfounded at this point. My LHS has some good guys there that know cars so I was really hoping the glitch buster would have solved my issue but it didn’t.
