Back when F1 came out the first time there was a company called BME. They made conversion kits for the tamiya cars. (1/4 axles). I had the complete kits for years.I sold them to someone two years ago. It was simple an bearing adpator and the axle fit. The also had the hubs. I still have one axle left I think but nothing else.
I plan on running foam out doors and rubber on carpet. GQ mades foams which I have sitting here waiting for the kit. Should get the kit next week.
Question are ya'll running - wheel base and 2 cell regular or shorty lipos?
