Transmitter ESC Recommendations

I bought a Traxxas Stampede for the chassis for a Rover using a Spektrum DX-9 transmitter and receiver. For the life of me, I can’t get the Traxxas VL-5 esc calibrated properly. It can be calibrated but needs to be recalibrated each time it is turned on, plus occasionally will go to full speed all on its own. This is unsafe!

I’m at the point of wanting to change out the electronics.
Is there a ground esc that is Spectrum compatible?
This there a transmitter that is compatible with the Traxxas VL-5 esc?
Any other suggestions?
