Hi I was wondering which spur gear to use for 2s lipo on a rustler vxl. I can't change the pinion because it is stuck on the shaft
What are you wanting to with your rustler? Bash or speed runs
You could always get a bit from almost any store like Lowes. The bit is for stripped screws.

I'd try to get the pinion off first. Is the set screw stripped out or something?
What gearing is on there now? There may not be many options depending on how small the pinion is.
My Black & Blue Rally is faster than your color...
once again...before over-doing things by drilling...what tools are you using to get it off? if not using hex drivers then you should try those FIRST. Your local hobby shop will help you get that stuck pinion off easily.
Also as always bigger pinion = more speed, smaller spur = more speed.
Try it like it is first, might be fine for what your doing.
