Not really. You mean to tell me that if a engine is totally cold it will fire in 5 seconds? Yeah right. I have my engines tuned exactly where they need to be. OS Rocket over squeezed the engine, and the piston was binding at the top of the cylinder, and with the power of the drill, snapped the wond, and broke a tooth off the little gear. The little gear is softer than the big one, because when something like the happens, or occures, it acts as a safty, so it does not break anything in the engine, or any of that. Its like Futaba has one plastic gear in their 9402 servos. Is the servo is shocked, or hit extremely hard, then the one gear gives, so that the whole servo is not trashed. It is also in there so the servo doesn't glitch with all metal to metal contact. Anyway, I really can't stand the roto start stuff, but nothing else for the Savage. I would love to put a Losi starter on it, cause they are alot better than HPIs, but they sit to low in the chassis and you can't get to em. Tryed it before I went and bought new gears for it. So yeah I got em, and fixed the binding, so this should last me a long time.
