I have inquired to about 17 online gear shops.
Some in Japan and China.
Japanese one just sent me a CDrom with their catalog. 0.6M is custom to them and not 'off the shelf'.
One promising lead I had, I sent to John H. since he would have more buying power.
My Q, is why the !#@$!$#^@%^ 0.6M?? I know some of their other rigs run it. The designer at Duratrax needs a smack up side the head.
hey just found this website cmehobbies.com, and they have listed on website a steel pinion 8t 2.3 dia shaft and a 9t as well. hope that helps.
Site does not list what pitch the gears are. Email them and ask.
Pic looks like 32P.
CC is 0.6M pitch.
I have been in discussion with BP hobbies for 5months now.
They claim to have the brass pinions in stock from a Korean source, but not on their site yet.
Feel free to bug Jim at BPhobbies.com
Their email is support@bphobbies.com
just emailed jim lets hope he responds.
