The new Pro-12/15/18 engines have been designed to achieve the easiest operation and max performance again. The all new Pro-18 big block engine creates incredible plenty of horse-power more than the previous .15 engine, which is the best choice for the out-law race. The new Pro-12/15/18 are available in several versions with the same mounting dimensions, making it drop-in easy to upgrade. All of series are available with built-in recoil starters ("X" type). The PRO-12BXP and PRO-15BXP are available for the previous RTR cars of the Thunder Tiger. The " K" type series engines feature a built-in hexagonal shaft starting system that can be operated to start the engine easily and quickly.
