Another Brushless Revo Project

I did a little more work tonight. I tore down the roller chassis a little more to get it nice and clean. I got the feigao 7xl in the mail today so I decided to
do a little mock up with the motor and tekno conversion hardware. It was pretty easy and I can wait to finish and get this thing on the road.

I just realized i ordered the wrong size heatsink and clamp from RCMonster......o well...I hope I can exchange it.
The only issue is needing to dremel a flat spot on the on the motor shaft for the elektri-clutch adapter.......no problem there.

So far so good.....just waiting on a few more parts and the lipo battery. Im going to use a hitec hs-645 high torque servo.
Im most likely going to get it going before installing the center dif and forward only......just to see the difference.
Also not sure what im going to do for gearing.....any suggestions?

I do have a few questions.

1. The wires on the MM esc.....red...white...black. The wires on the 7xl Red...Green...Yellow. What goes to What??
2. The Tekno instructions suggest installing the clutch shoe's in the leading position. Anyone have an issue with this?
