help with over heating problem???

Hey all! I need help as to why i have gone through 4 titan 12t motors in 2 weeks in 4 different trucks... im new to the hobby and cant figure out what im doing wrong. Also dont have the money to go brushless quite yet so looking for other suggestions... first one i cooked was in my daughters brand new slash but it was after i put the high speed gears in it that came with the truck... second one was in my stampede with a 19 86 ratio.. the third in my hpi blitz with 20 86 ratio and the fourth in my losi xxx with 16 86 ratio... any suggestions as to why i cant keep a motor in these things??

Im not familiar with the gearing in those trucks but my first guess is going to be heat. Spend $25-$35 on a heat gun to temp your motors with. You can get one for about the cost of one titan motor. Run the truck for about 5 min and check the temp on the motor. You should be under 200 if you are getting high temps you really need to gear down and just deal with a slower truck until you can afford to go brushless. If your pushing 200 after 5 min with a motor that was completely cooled off before you started your geared to high in my opinion

Ya i know that was the problem with the slash cause i went 23 86... but the other trucks caught me off gaurd especially the xxx with 16 88 i thought that was pretty low ratio but cooked in like 5min... too damn hot out for them without a fan???

novak has a spec 17.5 brushless system. it comes with 17.5 motor,and speed control.$219.00 I am running that system in my traxxas rustler and it goes good. speed control is onetouch setup. hope this helpfull for you.

Where are u running them?

Pavement and dirt parking lots....

pick up a baja, overheating problem solved!

also with the motors off check to make sure your transmissions spin freely. extra drag from a bad bearing or something can also heat up a motor.

This solution makes sense to me.

Thanks guys... not really what i was looking for sence i cant afford brushless let alone a baja... was hoping soneone would tell me something i could could chabge my gearing or something.... or that it is just to hot out to run outside without a fan... all things my hobbie shop told me. But thanks anyway

how about the gear mesh?? it could be off just a bit . that would cause it to heat up fast also. maybe some binding in the diff or tranny... good luck

You mean i might have my pinion to tight to the spur gear?? I think i do run them kinda tight cause im nervous about them being to loose a chewing up my spur gear... i will try that.. thanks man

That's a good point. Place a piece of paper between your pinion and spur to set your gear mesh.

Sweet thanks guys!!
