I’ve had this thing since the middles 80’s from brand new. Not sure what I was thinking back then painting it the way I did :lol: . Also, I remember battling with popping steering ball cups off every time I drove it, and had started my own teenage engineering on it to come up with a solution. What eventuated was a hacked into chassis, and a truck that never got used again. Also, very unlike me, I didn’t even have the front tyres on the right side

I decided to rebuild the chassis using styrene where it had been hacked into by me all those years ago

Gearbox looks ok

Motor wires twitched together to the speedie

So the body got an oven cleaner treatment, which after a couple of applications took almost all the old paint off

A bit of sanding and it was ready for primer

I painted the chassis with a satin black primer paint, then rebuilt it

For quite a few years, I’ve had these period correct hop ups waiting for the day that I get around to working on this truck

And an original front body mount (prior to the 3D printing options available now)

The JG steering hop up, mounted to a Kimborough HD servo saver is exactly what this truck needed back in the day, it’s a solid arrangement that I would’ve loved to have fitted to it back then

I picked the best 4 tyres I’ve got, gave them a soak of silicone spray for a week, and fitted them onto the rims, minus the internal locking rings, as they put too much pressure on them and they just tear (I destroyed 2 tyres trying this :evil: )

First coat of paint and a test fit to see how it’s looking

Started placing (MCI) decals

Finished the decals, and clear coated the body, fitted the roll bar, complete with original spot lights, and fitted the interior

Pretty happy how it looks out in our summer sunshine

Thanks for the kind words, Unfortunately these tyres won’t handle any running, if I come across a viable alternative at some point, I’d definitely like to give this a run on maybe 6V, just for old times sake
