Klander-I raised mine also. Right now my Rody kicks the MT12 all the way around in performance; couldn't have asked for a better engine. I'd surely love to keep it and rebuild the whole thing if any problems occured.
The NTs have been selling better than the GT at the LHS so if I get another ST I'll go with the AD2. For now its nitro onroad and the MGT.
BTW, my futaba steering servo took a dump on me so now I installed a HOT bodies throttle servo. It's a bit faster than the futaba and has more torque also. It brightens the chassis a bit also. I can't wait to take this ride out 2morrow!
