1/8th scales can be very hard on front belts. When I first got my MRX I was going through 2-3 each day for the first weekend or two. If you hit stuff (especially if you don't get off the power) you will strip the belt. Obviously you want to make sure the car is built correctly, but even then you can strip belts if you hit anything.

Keep the belts tight enough with the eccentrics, but not too tight. I generally ran mine tight and when they got loose I just replaced them. I always slap on a new set of belts for the mains. Save the good used ones for practice and quailfiers.
It also gives you plenty of practice swapping belts..... 30 minutes to swap both F & R belts is good
Keep your pulleys clean. I use a mechanical pencil to clean between the teeth. The graphite gives a little lubrication as well and minimizes future buildup between the teeth.
Kevlar belts will "chip" teeth off and the rubber belts survive impacts a tad better, but they shred suddenly with prolonged use. I tend to use kevlar and inspect between every run. A small "chip" on one tooth in the front will get worse very quickly. A small chip in the rear will survive a bit longer.

I made a belt tensioner into the upper plate.
The bearings are pushing the belt better arround the 16t puley, it is almost pushing the belt on the puley. Since I am using this I can run several races without changing the belt.

As seen from the side (same pic as in the MRX4-R thread)

oo that is too kool. I had this problem with my 4r. Check the front oneway to see if it has play. 1 shim is all it takes.

I had the same problem with the front belt. At the end of every main my front belt was stripped, even if I didn't hit anything. I just started putting the eccentrics in the tightest position and that solved my problem. The car isn't as free at first but it loosens up but it's not as loose as the stock setting.
