Tried the new xerun 120A 1s with LRP x12 10.5T for the first time in my 12th scale, no receiver pack is needed and got to say I like the feel of the HW compare to Tekin RS with v203 firmware(dont like v208)it has better bottom and midrange drive then RS which for my track it is necessary. Only problem that I have is temp on speedy is at the high side which I am not expected ESC with 120a rating, I have only use Boost timing with no SuperCharge so I guess the ESC/motor is not the good combo will try with SP motor next time to see if make any difference.
