I found the radio here in Seattle, new. I started racing with this radio without the parma mod (add slot car controller handle to the back) and I am comfortable to holding the radio as is. I have held other radios with the pistol grip mod and they felt front heavy with trigger offset like an airtronics now...I went to a Kraft (KO) pistols next and then airtronics, until now. I am going to give it a go without adding the mod, for now. The thottle servo is oppisite in that config too...pushing for throttle instead of pulling. (I think, as I remember)
I am searching now for a novak 21 spline disc... or arm to complete the throttle setup, I have the resistor support from the parma frame almost done, but no disc/arm for the throttle servo.
