where to buy 5mm bore pinions?

[RC-Monster Mike]

Good decision. Those pinions are worthless in my opinion. For the record, I had (still have) 5mm bore pinions in 32 pitch. I was unhappy with the quality so I removed them from my site. I have been searching for a better quality pinion since then. If I wouldn't use it(for quality reasons), I don't want to sell it.
