Frequent Questions & Answers
What does the nitro engine size mean?
How do I break in a new nitro engine?
Run several tanks rich and cool so the parts bed in, following the maker’s break-in guide. Rushing break-in shortens the engine’s life.
How long does a nitro engine last?
With good filtering, tuning and after-run care an engine lasts a long time. Running lean, dirty or without an air filter wears it out fast.
What else do I need to run a nitro engine?
You need nitro fuel, a matching glow plug, a glow igniter, an exhaust pipe and an air filter, plus after-run oil to protect it between sessions.
