No sweat, I am in the process of building a stroker RZ right now, try to find anything out about them. It seems like only a few have tried it, and some are just a little too busy to really correspond much.
A +4/+7 12 port RZ seems to be rare enough to consider building. I guess I just like to be different also. The motor really is worth building, if you're going to do it right.
The Rockets so seem to compliment the motor well, even though mine was ported for PTR's.
As far as mounting the servo, I'm almost ashamed to say it's zip-tied where the tors box used to sit. The cables don't bend that much, so it's hard to find a place where they aren't binding.
If anybody is interested in an MX ported set of RZ jugs with a head cut and rechamfered for 100 octane by Dan at Patriot Racing, let me know.
Motor runs great, just looking to go faster.
