I've been looking into getting a Slayer, but i want to know how long a ntiro enigne with last if it's well mantained or not. I want to know if you burned out a engine after 1 or 2 gallons, or 10 plus+ gallons without trouble and or what you've done to make it last so long. also what you did that made it die early in it's life. What is the best way to keep a nitro enigne running well and working for as long as it will go before needing a new piston/sleeve/rod etc. Post your stories good or bad about the TRX 1.5 2.5 and 3.3 engines and how to make it last a long time without problems. Thanks!
