Evening 

This is my first post so go easy on me and I apologise for the questions I am a noob to this hobbie. I am after some advice I was lucky enough to get a top force 're issue kit and was wondering if the tamiya stock bz motor would be suitable for use in it. I need some advice on what pinion gear to use for that 23t motor. Also do I need to upgrade the differential gearing from the aluminium ones to stronger plastic ones?. If anyone can recommend some hop up / upgrade parts that are easy to get hold of I would be greatful. 

Thanks

Tim

Hi Tim. If you haven't already then a full bearing set is a must for any tamiya. The gearset you speak of is 50529. I'll wait for some more experienced top force runners to come along but when I had the same chassis I found it very under geared, but that was with a brushless motor in it. Can't help on gearing for the bz, but I gear it's a great motor.

My first upgrades to my top force were ball bearings, aluminum motor mount , 50529 gears and wheel hexs. I have no experience with the bz but i checked the showrooms and the 21t pinion seems to be ok. Though I would upgrade to a steel pinion. With my brushless setup I use a 19t pinion. Recently i got df03 shocks and ceramic diff balls. I have on order yeah racing graphite shock towers. Here are some links to items i ordered.

The old rule of thumb for brushed was to reduce your pinion by  at least a tooth or 2 from the stock size when putting a faster motor in. Some of it needs a bit of trial and error to get a good balance of performance and heat as all cars will respond a little differently.

The main part is to have fun as you tune your car up
