My rubber belts last about 2 months. 3 gallons of running. If you are breaking them in one day, I would look at your pulleys and drivetrain stuff.

Are they rubber, option belts or the originals?

They don't break but the teeth get ripped off of them.

Thats about right for me also. 3-3.5 gallons along with 2 months of runtime. As Scott said, check all your pulleys.

i upload my pics to photobucket.com (any free photo web hosting will do) and then copy the URL address. you then click on "Insert Image" and paste the URL.

doctor
check your diff tensioners also (two rings that hold the diff and also apply tension to the belt)... make sure they are BOTH in the same position. another thing that could eat it up is when the tension is too loose. so put the tension to the max. the car won't free roll as good but will be easy on the belts....

Two weeks ago I put new pulleys in the front but not in the rear and it did the same thing. I was wondering if it was to loose? I have always put it on the loosest setting. The tension always seemed to be good for new belts.

I was also wondering if it could be from the bumpy sections in our track when we are on the throtle wide open in a big sweeper? You can hear the car skipping on the tops of them.

I am thinking of going back to the stock belts because of the cost and labor issue.

I am only selfish half the time. I let her get pleasure on the other half. Studded are better though.

yeah you don't want the belts to skip on a nitro car. i was surprised that i could get away with it with mod electric (really loose setting for more efficiency). give the stiffest setting a try

Your belt setting was too loose.

5mm - 6mm play is enough for front and rear belts. 8mm - 9mm play for middle belt. The power from engine is more powerful than EP cars, so always keep them little bit tight.

I soaked and cleaned the belts with Armour All liquids for durability and longetivity. Most of my belts last very long time except if damage occured from crashes or stones went inside the bulkhead.

I race once or twice a month.

I'm still going strong with mine. I don't race my car as much as I would like to, but I would say that I have well over 4 hours on my belts.
