Is it okay to restart your nitro engine while it is hot ?

or is it better to let it cool then start it back up ?
 
I don't see a reason why you can't. In fact, with some high-end engines, it actually helps prolong life to pre-heat them before starting (as it lessens pinch, and reduces stress on the connecting rod).
 
Because the other day when I stopped my truck to refuel it and went to start it back, they guys said that it damages the engine. I dunno how true this is.
 
restarting shouldnt damage the engine as long as you have a good tune and arent running hot to begin with. BUT it may be dificult to start, because once the carb gets hot the fuel will boil away befor reaching the block and the mill wont start.
 
oh....i c.......so it's prob best to let it cool to get a quick start then, right ?
 
There is nothing wrong with running it tank after tank. As long as your engine isn't over heating, you'll be fine. Think about it, at the track they run long mains. This requires refueling. Sometimes the mains last for 30-45 mins.

If you do decide to let it cool or take a break, just make sure the piston is at BDC. Your engine will be happier.
 
It's actually easier on the engine in general to restart it at normal running temps than it is to let it cool and restart.

Yup, because of the expansion/contraction of the piston and sleeve. Because the engine is already pre-heated, you don't need to worry about it getting stuck at top-dead-center. However, if you let it cool, you will still need to roll the piston down to bottom dead center, so the sleeve won't be deformed when it contracts (as it cools).

The only situation I can think of where this might be even close to true is like everyone says, that the reason for it dying was from overheating. As you know the hotter fliuds are the thinner they are and a really hot engine most of the oil will run or burn off.

But you have to be **really** hot. :D
 
Extremely, cause the only time i ever see that happen was the last time I lit some nitro, thanks for all the help guys.
