I wa told that when it gets hot outside (80-100) its bad to run your r/c and that it burns up your motor?

is this true? if so how?

you might have to retune just keep an eye on your temps

yeah i know that............but i dont understand how the heat can ruin your motor if your temps are good and its visible smoke

cuz some people are a little bit dum and dont understand why there stuff runs hotter when its hot out . Running your motor in the heat will not hurt it as long as u tune it right. Last year at the Kyosho challenge track temps were about 130* and I am still running that motor 8 gallons later.

oh wow...........thanks mike

yupp and just to give you an idea of how the pros do it lol, Adam Drake was running his Sirio at 300* all weekend, the motor was tuned for max performance...so what im saying is dont let temps scare you, just be resonable

This hobby is HUGE out west... California and Arizona...outdoor temps have little effect as long as you tune correctly.

isnt 300 a little hot though?

Technically, Yes. But there are things to keep in mind. Ambiant temps play a big part on what temp an engine will run. The oil will only cool an engine so much. If you richen an engine TOO much, to try to bring the temps down in excessive heat, you will run the engine too rich, causing extra stress on everything. If this doesn't make sense, intentionally flood your engine, then pull the pullstart.... Now imagine all that extra backpressure when the engine is turning 30,000 RPM + SOMETHING is going to give....

Get used to watching the way an engine runs when it is tuned right, Watch for good smoke coming from the exhaust, and LISTEN to what an engine sounds like when it is running right. Once you get used to those, it'll be much easier to notice if the engine isn't running right in different climates.

+10 u said it all there bro

ok thanks newguy.......I know how to tune by ear and all that but i just was told that 300 is too hot for a traxxas motor.......so w/e, thanks for explaining

My first T-Maxx would run all day at 280, but it had great smoke, idled good, and never lean bogged. I got 6 gallons through that before I sold it, and I got it used. I wouldn't be surprised if it got close to 10 gallons before it decided to quit.

Running temps are a starting point, but not the only way to tune. So many other factors affect temps. Ambient temp, airflow, cooling head size, etc.

Also, don't make the mistake that a LOT of people do. NEVER tune an engine to temp with an oversized cooling head. The bigger head will drop temps 20-40 degrees or more, and some people think that it is then ok to lean it out. Too often, this results in running too lean.

now watch everyone go out and run their chit at 350 and come back and say u said it was alright lol! How can I put this nicely...i would say that there isnt any guy in here, myself including, that could benefit from the power tuning that the pros do. Those guys need that extra bit of power;but for what we use it for, it is really uneccessary. Your stuff will last longer if u run it a little richer, im not saying run it at 200 and let it be blubery rich, but i dont think the extra power is worth the decrease in lifespan. I only say that u will lose some life on the motor because, when you run them THAT lean, you are on the brink of perfect tune and lean bog/burn up your motor. If you can find that perfect spot, more power to you, its just findhing that tune thats the tough part lol

Not to mention, the PRO's just have to go to their sponser and say, "I burnt up an engine getting that 1st place trophy for your company." and they get a new engine...

If you are out bashing, keep it a little on the rich side (not enough that it won't run good, and loses ALL performance), save the "Race" tuning for the track.
