1. The break-in process allows the engine parts to perfectly fit to each other and properly protect the parts against unnecessary wear. The fuel used for break-in must not contain more than 15 % nitromethane and no less than 20 % castor oil. Do not use fuels containing synthetic oil during breaking-in. For break-in, we recommend installing the engine in the model in which it will be operated in the future. This will allow you to test and adjust not only the engine, but also the entire fuel system and RC throttle control. If the model has an engine cover, it should be removed for breaking-in.
