Have a Rex that I put on Jarod's old diet, its been on the shelf while I work my way up the heli ladder. I'm only at the Esky FP stage, but I like to build ahead of myself.

I have the 15t pinion that comes in the Trex kit, but I've checked and seems like I could use a 17t or 18t pinion for much better results.

Only problem--where do you find the 0.5 MODULUS gears? I have a 48pitch 17t, but it doesn't match up well enough with the main gear, obviously.

Anyone know a quick answer as far as the vendor to contact?

Thanks.

Johnny

So those are 0.5 modulus pitch? Just wanted to make sure, the pic looks just like the car ones I got at the LHS that are 48 pitch and don't mesh as well as they should.

Eco 8 pinions are certainly the right ones, just make sure you specify the 3.17 shaft as they also come in 5mm

we can never have too many, can we ?
