You are right I was a little impatient, this car is taking me much longer to get set up then I originally anticipated. It turns out that I was wrong about the receiver. I was pretty confident that was the issue but apparently it was not.

I plugged in my new spectrum sr310 3 ch surface receiver and bonded it to my dx3r and I am still getting the exact same problem

I have a jr racing z9100s digital servo. I plugged in a old crappy servo I had laying around to test and it did the exact same thing so I eliminated the servo as being the problem.

I have a brand new never used Reedy 540-m3 17.5 motor. I tried also with a known good motor that I had laying around and same problem.

Battery is brand new and fully charged. Batteries in tx are also brand new. My soldering is also very good in my opinion so I don't think its that. That only leaves the speed control to be bad. It is a LRP sphere competition (sensored) 2007 edition. It is old but still in good shape. It was working perfectly fine on the car I was running it on just before swapping it over to the lost 22 4.0. It allows me to program it perfectly fine and all the lights are working correctly. So I don't see how that could be the issue.

Ive also tested the entire circuit with my old team Orion 4800 mAh battery that I was using previously on my other car (same issue occurred) so battery being the issue is eliminated.

I am getting power to the steering servo because the wheels go full left and full right when barley touching the steering control on tx.

No response for throttle.

I apologize to everyone if I came off rude and impatient in my previous posts. I am dealing with a bit of frustration with this whole process as it was supposed to be simple as swapping everything over and it working just as it did in my other car. I honestly don't know what happen and I really don't want to drop $250 on a speed control if I'm not even sure thats the problem. I already spent hundreds more then anticipated .

Thanks in advance everybody.
