Working on Schmenzer’s NAT Part 2

I worked more on the NAT today and it was time to get the steering squared away.

Here are the parts I used for the servo mount:

Axial Aluminum tray from a Scorpion
3 Racing Aluminum Servo Posts
Kyosho Mini-Z Wheel Bushings as spacers under the tray

First up was modifying an Axial Scorpion servo plate to use with the JR ST-126MG servo. I use this servo on my 2.2 rig before I picked up a JR 8711 for it and it was pretty decent on that rig so I am sure it will be fine on the NAT. The servo puts out 142 ounces at 6 volts. I am probably going to get a BEC in case this thing stresses the stock ESC too much. We will see how it goes.

I screwed the Scorpion plate down to a chunk of 2×4 so it would stay put while I drilled and countersunk the MRC holes. I simply used the stock mount as a pattern.

I installed the mount to the axle using some Kyosho Mini-Z spacers to raise the plate a bit.

See the Kyosho spacers?

I used 3 Racing servo posts to screw the JR ST126MG to.

Before I get to the electronics I had to finish up the steering. I used Cody’s stainless steering rods and parts from the stock drag link.

Stock parts with the new stainless replacements

I simply cut the ends off to length and bored out a hole to thread the stainless steel rod into. I measured a 95mm spacing on the main drag link. Good to know if you want to retain the stock toe. Of course you can adjust the toe with the threaded rod but, for me, stock seems fine. The stock steering ends are nice and strong and since I didn’t have any of the link ends to do this right this seemed like it would work fine. And it does! The stainless links give good clearance and take the torque of the JR servo fine.
