Maxima have released a photo of the forthcoming B4S nitro engine. Soon available with a low profile heatsink (B4S) or standard heatsink (B4R), the engine is based on the latest O.S. Speed engine, a guarantee of quality. The engine is matched and comes with Factory tuned parts and pre-run to increase the overall performance. The B4S/R engine will provide more power and yet offers more runtime. Both engines are available for pre-order and you can add a special back plate with your name engraved.
