Does anyone knows how to gear this machine?
IŽll be using a brushed 23t or 19t with NiMH, no racing, just a few rides in the park.

Does someone have spares for this car or know where to get them?

I drove one of these back in the day, great car. Just watch the front top gear case cover, breaks easy. As far as gearing, I would start with a 84/17 for a 19t motor.

i had the special version of the mr4-bc (still have the box and instruction book somewhere).
seem to remember the front end was expensive to replace as the graphite shock towers ony came as pairs (front and rear).
gearing i would go for 19t pinion with 84t spur

thanks for your advice guys, IŽll keep that in mind! Fortunately I have tons of spares.But no spare wheels, and these seem really hard to get. I think IŽm gonna try to make a hex conversion with modern kyosho or yokomo wheels.
