Ok so we did some testing this weekend. Let me know what you guys think.
We did a process of elimination. He is currently running a traxxas reciever and the traxxas cheap Radio the T3 (he is only using this till he gets another radio owed to him)
So we did this. I have a spektrum DX3 so I took my extra reciever and put it in his car, we ran it with both a 7cell and a 6cell. Guess what perfect no glitching whatsoever and the temps on the ESC were fine.
Next we put in a JR receiver. Result super bad glitching.
Next changed the Crystals out in the JR and the Controller. Results. Bad glitching.
Next. Used a totally different controller and JR. Result. Super bad glitching
Our only cure was when running the Spektrum setup.
Is it possible that this ESC and Motor require a much more high end reciever?
