i have had the reflex 12 and it was sweeet but i had to get rid of it. For the servo mounting, you need a special servo with tabs on upper and lower parts its in the manual and you just put a screw on bottom with a lugnut.
As for the kit the front suspension gives alot of steering which iis awesome. I have seen some hybrids of crc with trinity front ends.
hope to anwser a few q's of yours
