Arrow Racing GTR-21 .21 Race Engine v2 *updated crankcase


Hey Everyone if you are looking for a Offroad motor with a great price point, then the Arrow GTR-21 is it. If you like the power of the OS V-Spec series nitro engine then you'll love this engine. Same powerband(maybe a little stronger) as the OS V-Spec, with a tighter pinch, so the engine will last longer. I recommend you take you time with break-in because of the tight pinch the engine comes with. Great engine at a great price. Oh yeah it uses OS standard P3 & P4 turbo plugs which is a plus!
