The Team Orion Wasp 28 with Pull Start # 80500 is a big displacement nitro engine intended to be used on vehicles such as monster truck, buggies, and other rc nitro vehicles that originally came equipped with a smaller .21+ nitro engine. The Team Orion Wasp .28 was designed to be a powerful bolt in upgrade for many of these types of RC vehicles.

This is what Team Orion says about the new Wasp 28: The Wasp .28 is ideal in monster trucks such as the Monster GT and Savage where more power equals more fun. It can be installed in any vehicle that uses standard .21 size engines to improve performance in a non-competition environment.
