Hotshot 2 restoration

[Caronte 3]

Hi all, I'm 42 and I want to restore a couple of rc tamiya cars that my brother and I build when we were young, and to have fun now with our sons.

My fathers bought in 1989 in Japan a Hotshot 2 and we with our father had a lot of fun building it and running it . We also bought a Mud Blaster too and had a lot of fun with them.  Now I want to show that fun we had to my sons and I've loved for that vintage cars that were keep inside a box and in restoring them.

I've started with the hotshot, and as you can see in the pics, we had a lot of fun with it, it had several crashes break the bumper and was replaced with one done with an aluminum tube unfolded,

 

that broke the main body (note a metal piece over the engine) 

 

 problems with the stabilizers arms (replaced with a shortcircuit boardto avoid friction)....

The speed controller resistance had broken the ceramic by a crash...

Engine replaced by a trinity engine to have more speed

the speed controlled partially burnt... And a lot of dust by now,...

As you'll see in the next posts you'll be able to see that the cups and the drive shafts are really damaged by running and need to be replaced.

In those days we wanted to add the ball bearing set but can't afford it, but nowadays seems quite cheap and in thinking on change all of them. If course this remplacent will imply to change all cups (wheels and diferential) and dogbones and here is, by now, my question, I've been reading looking for an actual answer and what parts I need to be running it again. What do you suggest me? What combination is most durable and cheap? There's any compatible somewhere around?

I've stared to clean the front drives with an ultrasonic bath and I'll be uploading pics in a few days.

Thanks for watching and feel free to comment anything. Every advice is really welcome

Thanks all of you guys for your thoughts and advices...

Thanks Kontemax for your references, Tamiyabigstuff i'll let you know if I finally need them,  and what a pair of hotshot's Chevelle...

My kids and I have worked on it again and finally we opened the body to find the servos and electronics.

Here I have another question, do you recomend to change the mechanical speed control by an electronic one?  It had burnt one contact (25 years ago )and was repaired with a silicone part that doesn't burn.

 I was thinking on this ESC HobbyWing QuicRun 1:10 Brushed 60A QuicRun 1060 . I'm planning not to change the motor, in '92 I've bought a Trinity Slot Machine ROAR'91 Stock but I don't know if this motor and ESc will be compatible. Any suggestion? 

Ditferential without the front arms... note the diferential cups and its wear

 

Rear Diferential with all the dirt... next step to work with... note also the cups and dogbones ...

I'm planning to open the diferentials to see how they are. In this case what grease do you recommend? and for the cups, i'm planning to substitute all the nylon/plastic bearing for ball bearings, Do they need grease too? oil?

Thanks again for your coments and I'll keep you tunned

That motor would be fine with a 1060 esc, it will actually give you headroom to increase the motor down the track if you want
