Sealing nitro engines
Traxxas says use only the o rings to seal the carb & engine,
everybody else says in addition, use rtv sealant too.
What does everybody do in theirs ?
And exactly which rtv do you use ?

Lucky 7. It's what was recommended to me by an engine modder with years of experience.
Don't know about Traxxas, you may want to ask them yourself if they have a help forum. I know some sealants aren't nitro proof and could possibly enter the enginge and gum things up pretty bad.
I seal the back plate, the carb neck where it seats into the engine block, and the carb needle casing where it meets the carb body.
Good luck.

It's deff not a gel consistency, a lot more liquid than that coming out of the little bottle....yah, it's more like loctite. I use a toothpick to spread it.

RE: Sealing nitro engines
I would not seal anything that could come in contact with nitro fuel or nitro exhaust with RTV. Lucky 7 or 1211 threebond, otherwise known as yamabond. nitro fuel will break down RTV.

RE: Sealing nitro engines
Autozone sells sealants that are fuel proof so they probably hold up to nitro fuel. I have been using the cheap walmart stuff since I was a kid and it has never once broken down due to fuel, heat, or whatever other factors it experiences when on an engine. I use it to seal my carbs and backplates on every engine. I can't remember the brand, but I do know it is silicon RTV.
All of the sealants are probably in the same ballpark pricewise, so if you've never used one then just go with the best of the best, and from what I've read here it sounds like that would be Lucky 7.

RE: Sealing nitro engines
I definetly suggest sealing your engine, I use regular gasket maker from Autozone, so far it has held up? I fought the tuning of an engine until it was sealed, after that not issues.
