"A HL controller WILL NOT work on the Matorro KT, even when you switched the crystal . Seems that there is a different between HL and Matorro's controller. Does this mean that the circuitry on the KT is different from the one onboard typical HL S&S tanks?"
Did you switch out both crystals on the sender radio and the receiver board on the tank?

No. What I did was to take out the crystal on the Matorro controller and mount it on the HL controller. Isn't this suppose to work too?
