They do. I can feel the edge fall off after about 3-4 laps. Then it runs "normal" for the race and begins to fall off again towards the end of an 8 minute run. Not to the point where you can't clear jumps or anything but just kind of soft feeling.

On a similar note, I stepped down a tooth for our 8 minute main last week and pulled the car off the track at 190. I went from 33/68 to 32/68 and gained a ton of heat with my 17.5. Normally I finish the main at around 150. I noticed the mesh sounded a little noisy on my warm up laps but when I checked it after the race it was fine. At that point, I noticed some roughness on the face of the teeth of my aluminum 32 tooth pinion gear. That's the only thing I can think of that would have caused the temp increase. Crazy....

Maybe that's why all the other guys look at me like I'm crazy when they park their cars before the race and I'm out there running laps like Ricky Bobby LOL. I probably take the edge off my battery long before it starts lol.

hey does anyone know if 4wd front wheels will fit on a b5m FL without any rubbing? I have 2wd wheels that fit fine, but i have a greater selection of tires for my b44.3 and it just gives me a bit more versatility

Plus they are wider than 'legal'. If your track doesn't care then you could but its probably going to feel weird.

Are you confusing hex size and offset?

No, I am not sure how or why hex size is an issue.

The offset it the same on the b5 wheels and b44.3 wheels, except the b44.3 are thicker hense why they are rubbing. My question was is anyone was using the front b44.3 12mm hex wheels on a b5 without rubbing issues.

False, the B5 wheels are concave, while the B44.3 are convex. Basically if you set a B44.3 wheel face up on a table it is a dome shape from the outer bead to the mounting hole. The B5 wheel is gonna be the opposite. This pushes the B44.3 wheels further in than a B5 wheel, which causes the rubbing. Use the right wheels. Just that simple.
