Vintage Nikko Fox Frame Buggy Build How-to. Lots pic's

I'll start with taking apart the gear box.
You have to remove a pressed on collar for the wheel on the oppisite side of the motor to split the gear box.
Vise grips does the job. You have to give the axle a little push with your finger from the other side to get it to pop out enough to grab. Then just give it a twist and pull.
The second challange is to remove the pressed on pinion gear from the factory motor.
I supported the back of the gear with a wire cutter over a bench vise, letting the shaft stick though one of the holes. Then used an old drill bit as a punch to push the motor shaft out.
To install the gear on the new motor, I supported the motor shaft from the back side on somthing solid. Placed a socked over the (soft brass) gear for some protection and gave it a few taps with a hammer. The gear is longer then it needs to be, so it can be pressed on most of the way.
The inside of the gear box is built pretty well. Has replaceable bushings, and a steel plate to keep every thing together and nylon plastic gears like you would find in a Tamiya.

The motor I used is a Traxxas 380 18 turn. It's very long. Had to make some holes on the end of the gear box for the terminals and rear shaft to stick out.
Before putting the gear box back together I filed it up with with some fresh grease (original grease was 25 years old, probably older then some of you!)
The servo used was a "micro" I belive, from a pro-pulse radio shack 1/18th scale R/C. Mounted nice inplace of the factory electro magnet. The servo saver had to be custom made. Steering Linkage with Ball cups from a pro-pulse.
The ESC is a Novak Sport reversible. The radio is also from a Pro-pulse. The buggy uses 8 rechargible AA for power. And the charging jack is still functional. I made an adapter to use a normal battery pack charger on the built in jack to recharge the AA's.

Done for now.

Unfortunately the original rear tires are too damaged to use. They are cracked with a large flat spot.

Here is some test run pic's.
Next up is to replace the original springs. I have some oil-filled aluminum 18th scale one to install.
These factory springs are waaayy too hard. Typical for Toy Grade R/C's. There only good if you plan on dropping the car from your roof.

One more pic.

Why did I do all this work for an old toy?
Well, I had one as a kid. A few actully. Radio Shack used this chassis on a few of there buggies. Like the "white tigar", but was changed to use a 7.2 pack instead. It also reminds me of the Tamiya Hornet.
The chassis are built well, over built really. But the stock electronics are terrible. They get glitchy if it's more then 15 feet from you, and you have to be going forward or backwards for the steering to work. And they are painfully under powered from the factory. Once they have a real motor and servo they perform geat, well better once the bouncy springs are taken care of.

I need a new diff or even some replacement gears for the diff for my Black Fox F-10

Any ideas of anywhere selling Nikko spares?

I think the F-10 is the full size 10th scale copy of the Tamiya Hornet. Well the gear box anways. I'm pretty sure you can swap parts with the hornet, IIRC I had to do this to get some good gears in one of my radio shack Sagita (same as golden arrow).

Then get on ebay. I've seen several of these 1/14th one go for $20-30 shipped. Dont forget  to look for Lobo's & Radio Shack. Both made by Nikko.
This lobo has the Nikko Fox gear box, but the Turbo Panther (also 14th scale I think) has a different gear box.
