Oh...my god....the engine's quality seem to have serious issue. Better to forget this model....But I like it have a complete sealed gear box. Better then normal truggy, everywhere is mud/sand after play.
My friend played the TNX 5.2R (former truck version of Nitrage) in TKO. My Savage X (already changed to 18T clutch bell and 47t spur gear) still could not catch his TNX5.2R But there are problems with his truck.
