Ultima rear end, with Twisters motor, and Winner receiver.
Ultima work in progress, with shock tower upgrades, and RC10B4 front wheels.
I've been working on an Ultima for quite some time now. The hardest thing to find has been front wheels. I've had to use B4 front wheels, etc.
I found that the old shock collars got a bit brittle also, so I used an old Associated set of shock clips.
One of the best finds for me was a company in the UK that can supply vintage un-painted bodies. I picked one up for the Ultima and an Optima that I am working on.
If you find any stock front rims for the Ultima, please let me know. It is one of the only things that is gating me from moving forward with this project.
I've found that the Reedy 3300 Ni-MH stick packs will fit in the stardard Ultima also.
