i just ordered a savage XL and I wonder what fuel I should you use in it? I currently have an hpi bullet mt 3.0 that have over 3 years. My local store gave me 25% CRF power fuel from team Orion,since then my bullet MT is still running good and have no engine issue. So do you know some good nitro fuel so I can get long lifetime and good performances for the XL motor ? Since I heard that the engine might have some problem I prefer to ask so I can get long lifetime with it.
