you may have already figured this one out already since I just found this ... It's a ball type differential, but I just had it set pretty stiff. Once you've ripped into the case and pop the diff open you'll see. If I recall correctly I had the underdrive set in the case. No problem, glad you could put it all to use.
Hi all, it's been asked but apparently never answered .... does anyone know the wheel size of the Marui Fr/Rr wheels for a Ninja? I've currently got Kyosho hexes on my Ninja and running Low Pro 2.2" wheels/tires, but I'd rather throw the original wheels and some replacemnet tires on the old girl. Thanks Dave
