Ofna Ultra GTP Conversion!

[BL_RV0]

So, my next project begins.
I just got home from the LHS, ordered the Ultra GTP kit as well as the Porsche 911 body for it!
I can't pick them up until next monday or tuesday though because I'm taking a trip with my dad.
I'm going to run my Hacker C-50Maxx, MM, and 5s with a TrueRC BEC. Also going to run a HS-645MG (oddly I have them in all of my projects)
Gearing will be about 14/45 (58mph)
