Advice/Help wanted with a Yokomo MR4 TC Custom

[Roadrage]

Hi.

 

Picked up a box of spares i won on ebay yesterday. Amongst them is a Yokomo mr4 tc custom roller. I have read around the net a little and realised it is a vintage RC model but is in a very good condition and came complete with the original box.

 

Being a bit of a novice still i dont know what engine or pinion gear i should put into it and can find little information regarding this on the net. Should I look for a brushed motor/esc to keep it with being original or go for a modern brushless system? either way I still would like advice on what engine and pinion would be best suited to it. There is a spur gear still in place although I dont know what it is. I have added some pics too.

Used to race one. Great little car.

 

First thing I'd do is ditch those horrid wheels/tyres and ugly shell!

 

As far as power goes, it is a pretty efficient drivetrain, but the rear belt and spur are a little fragile, so my best advice would be to fit a brushed setup (19t or above) running 2s lipo batteries. Gearing really depends on where you're going to run it and the balance of acceleration vs top speed you're looking for. Start with a pinion around low to mid 20s (in terms of number of teeth) for use on the street, would be my guess.

Thanks for the reply

 

It is my intention to run it on the streets well the car park down one of my local parks, and yes tyres will be changed and ill proberly spray the shell although I have a spare couple of shells ready to paint one is a honda accord and other is a nice lexus shell i bought for my Kyosho but never got round to painting.

 

I run a 19t Orion in my Kyosho so a similar system would be good from what you are saying and many thanks on the pinion I realy have no idea on pinions to spurs atm even after reading the sticky thread im more a mechanic type than an electrical type of person lol.
