I got the gravedigger and the radio was the 2.4 ghz but only one button for trim. In short what is the difference with this radio and the TQI?
Programmablity and dockability.
The single button TQi look-a-like radio is very limited as to what you can actually adjust on the radio. As far as I can recall, there is no throttle trim, only steering trim, but both channels are reversible.
The TQi has lots of adjustability and can be dockable with purchase of the proper parts.
Whatever it is I just typed... could be wrong.
