Here is mine. Not completed. I am going to shrink tube the wires black. I was surprised at how nice everything fit.

Looks good, I have a Lo profile servo, but this is pretty much the set up I'm going with.

If you're having trouble with ball studs stripping out you can also put grub screws in the empty holes. This also makes your bulkhead more sturdy. The manual actually tells you to do this in the rear but you can do it in the front too.

I've done that to mine. Hope it keeps from happening tomorrow.

Also, don't over-tighten your ball studs when you screw them in. And if you're using a electric screw driver, go slow so the plastic doesn't over-heat and set your clutch low. I like to use a wrench for the last few turns so I don't strip the bulkhead.

I've never broken a front pivot block and you're a better driver than me. I think you're safe with the kit plastic.

(Yes, I know about multi-quote. Just reading back through old posts. Sorry...)

I mounted my Futaba Rx, which is bigger than the KO, right side up along the side of the battery. I just layered up about eight pieces of servo tape to build a flat spot for the Rx. Seems to work fine. We'll see if it holds up. Mounted the R10 capacitor opposite the Rx but in its side. Power switch mounts vertically on the side of the rear bulkhead behind the ESC on the right side.

I think this is what Jared did too.
