Gearing help

what is strange is that I have a buddy running the same setup, same system in his buggy, we run on the same track, but he is geared 45/15, and I am geared 48/17. He does not run the fan and his temps after a 15min main are ESC160F Motor 145F. If I don't run the fan, my temps for the main were ESC 201F, Motor 198F. He also drives harder than I do. Something has to be wrong. Is my gearing that much different? He is running identical hotwire settings as well.

I have tried 15/48, 16/48, as well as 17/48, and temps were virtually identical to what I am getting now at 17/48.

What gearing should I try next? at 15/48 the buggy was about the same as nitros speed wise (too slow), but ESC dropped to 185F after 15 mins, motor stayed the same as when running 17/48.

I am running the proper mesh, there is no binding, and my buggy is only slightly heavier than my buddies.

PLEASE HELP! I am regretting the switch to tekin!

Something isn't the same. There has to be something you're overlooking.

What is your timing advance set to? How much heavier is your car, that could be HUGE.

Go back to the 48/16 gearing as that is the same as his. However are you guys running the exact same car? 1/8 cars often have either 3.3 gearing internal or 4.3. If you guys have one of each your gearing is NOT EVEN CLOSE!

He runs a losi 8ight 2.0, and mine is the 1.0

You guys might drive completely different than each other too. If his driving style is easier on the electronics this alone could be why he's cooler. Have him drive your car , see where the temps are.

If he's easier on brakes that is a huge factor. I often run cooler than a friend that has literally the EXACT same car down to the servo and I'm 20 degrees cooler than him.

I did, and temps were identical

To his or yours? LOL

Are you using the same device to temp both cars? Are you using the same radios, servo's and batteries?

same temp gun (same actual gun, not just same model...), different radio, same batts.

maybe something is wrong with my motor? I have a CC blower on order. I hope it will cool stuff off a lil

I personally think the problem is with the loose nut behind the controller...

you don't have big/heavy tires on there, do you? That could do it. If it isn't that or binding, driving style is probably it. Try driving a little slower. Slower acceleration for sure should lower temps.

Btw brian, love your theory.

lol, no heavy tires (Caliber on proline dish buggy wheels) Brian, you may be right!
