Tekno RC Blok 21bm .21 Competition Buggy Engine, Not Broken In

About this part

Blok 21bM .21 competition buggy engine. This unit has not been broken in. Designed mainly for buggies, though it also suits truggies. The 21bM offers a smooth, linear power band and good fuel economy, which suits high-level competition. The bottom end is gentle, the midrange and top end pull harder for a quick takeoff and strong straightaway acceleration. The engine uses a long-stroke piston and sleeve, a DLC-coated silicone-filled crankshaft, a laser-etched low-profile cooling head, and blue 6.0 and 6.5mm venturi. Its components interchange with the popular 21aP. It comes with the 21J carburetor, which is well regarded for tunability and steady performance across a wide range of temperatures and humidity.
