Jake, let me suggest this engine might not be the best for your application. As GRJ suggests a conventional engine would be better. Also this engine has a small can motor not really suited for continuous running. On the other hand Williams engines are nearly bulletproof and also start in forward. On newer Bachman engines its important to make sure they are lubed as many have been found without grease in the gearbox but other than that they will run all day with few problems.
