Default Need some help

Hi everyone,
I am new to the nitro world and to this forum. I need some help with my nitro thunder tiger EB-4 S2 Pro. My problem is that the engine is getting hot and the only way i was able to no that, my controler has telemetry for temperature. And when i ran my car last the temperature was at 245 degrees and my controler alarm was going off. So what is a good temperature my car should run, so any information would be great.

Thank you

Hello Clark and welcome to RCTech!

There could be some other factors affecting motor temps. Maybe oil content in fuel too low? Or maybe the engine is out of tune?

Your engine should be happy between 200-220. Richen it up and aim for this.

I don't have any experience with Spektrum telemetry so I can't say if it's accurate or not. I would still check the head temp in a couple places with a temp gauge just to make sure it's in line with your telemetry.

Want a real low tech way of checking to see if your motor is running too lean? When it's running spit on the head. If the saliva boils off (like an egg frying) it's too hot. If the saliva just stays there you're running cool and could maybe lean it out some more.

Also it's not a bad idea to tune for performance and ignore the temps. Some engines do not mind running hotter. A running engine will tell you everything you want to know. You just have to listen to it. You did say you were new to nitro so knowing how to interpret motor sounds will come in time.

Good luck with it. Nitro can be very rewarding.

there is not a perfect temp... 245 is not bad.. if your tune is right or relatively right the temps will take care of itself....unless you have a mechanical problem..... tune for the performance... as long as you stay under the 270 mark or so you should be good..
