Vintage Mk1 Hotshot gearbox upgrade.

[FoxShot 280]

So, i have an original 85 Hotshot I scored about 18 months ago on Ebay.

it came with some spares, and a few mods along with the original release front arms and pivot balls (not fitted, and the updated versions).

 

in getting it running it received an eTronix 4950KV Brushless setup. What i dont want to do is destroy the original gearbox internals or cases. Along with a full RC Channel suspension upgrade, and Mk2 Chassis tub.

Will I need new drive cups too? And will those remove the need for different length drive shafts?

This will potentially mean I end up with 2 Hotshots as i also bought a new body as the original one was so well cut out and painted.

Also, does anyone recognise the Hotshot? it had a grey and green painted chassis when I got it, with silver painted gearboxes

As It Arrived.

How are you getting on with this? I have a similar dilema as lacking a front drive shaft on the original car. Have you resolved with re-re parts on your car?

Not done anything yet re the gearboxes. Will probably just order late model cases, gears and bits. Then I will officially have 2 Hotshots

Those RC Channel parts really are lovely! 

In answer to your question, if the slots are worn on the gearbox drive cups, it's probably a good idea to replace them. Same goes for the wheel axles too. The main difference between the gearbox cups on the re-release is that they no longer have the incredibly tricky to fit and remove C clips that stop them popping out. So my advice would be, if you want to keep the gearbox housings and internals safe, buy a whole set of new ones! Either way, the re-release also has different length drivehsafts front and back, so whether you only replace part of the drivetrain or all of it, you will still need 4x gearbox cups, 2 front driveshafts, 2 rear driveshafts and 4 wheel axles. The good news is that on the re-release the wheels axles are the same front and rear.

Hope that helps and look forward to seeing this finished!
