I have an EVX-2 ESC in two of my Emaxx trucks. One is a 3905 and the other is a 3906. Both have the EVX-2 and Titan 550 motors. But for some reason, I'm having a heck of a time with them.
I use a Spectrum DX3.0 radio and SR3000 receiver. At one time, I was running the trucks with this exact set up. But I smoked one of my Titans in the 3906 and so it's been sitting. I was planning on selling my 3905, so I got it out the other day to get it ready to sell. I wanted to make sure it all checked out first. So I hooked my SR3000 up to it, and can't for the life of me get it to bind w/ this ESC. Nothing I do works. The receiver flickers like crazy, especially if both servos are plugged into it. Litterally nothing I do works. And I run this radio in two Revo's, a Pede, and Rusty with no problems. But this EVX2 is just not jiving and I can't figure out why.
I put the receiver back into my Pede to make sure it was ok, and it worked like a charm. I just don't see how it was possible that two diff Emaxx trucks would both have bad EVX-2 ESC's. Esp since one of them is nearly new. I'm not sure how to even troubleshoot an ESC to see if it's working properly or not.
I do know that if I unplug the ESC from the receiver and plug it into say the steering or aux channel, the veh suddenly wants to take off like a shot! It's got a mind of it's own. But my servo's aren't turning, and even a brand new servo plugged in to the receiver isn't turning right, and i know it's good. Something is wack and I don't know where to start.
Also... I got my 3906 back up and running, but with the stock radio paired to the EVX-2. It seems to be ok, however I noticed that I didn't quite have the torque that I thought I would. I checked the slipper and it was nearly fully tight. But the batteries, motors, and spur gears were all super hot! I don't understand why either. I'm very experienced with Emaxx trucks, and most all the other Traxxas trucks. And I was shocked. There is no reason why all of that should be hot. I'm geared at 66/18, which is fine, and was running two fully charged 3300 batteries. Should have been "ok". Certainly not "hot". What could it be???
