Default Tamiya F2012 with F104 Chassis

Hi,

I am wanting to build the Tamiya F2012, I'm sure you know it comes with a F104 chassis.

Now, here's the question I have about the electronics: I am wanting to put a brushless system in that car, and since I am limited to a 2 cell lipo (without making major mods to the chassis) I want a high Kv motor. The car is 1/10 and I found a brushless combo online that is 6000kv (or thereabouts) and it is 1/16 scale.

Am I ok putting a 1/16 system in that 1/10 car or do I have to stick with the 1/10 system?

I realize my questions are mostly dumb, I am new.

You are better off to have a combo for 1/10th cars, therefor you don't need a special motor spacer to be able to mount the smaller motor. It also can handle the weight of the car better, otherwise i think the 1/16th motor type could run hotter then normal.

I presume you are going for speed runs rather than racing, a 6000kV motor could be capable of pushing it to over 100mph, the chassis wouldn't be able to handle that sort of speed. If you can get an adapter plate to fit the 6000kV motor it wouldn't have the torque to get it moving with the extra weight of a 1/10th F1.

If you are planning on racing it you will want a 21.5T motor, that is the only wind allowed. If you aren't planning on racing then I wouldn't go for anything faster than a 13.5T motor, which is around 3000kV, even that can be undriveable if you don't have enough grip. If you need more grip the Tamiya TCS tyres give much more grip than the kit tyres.

Yes, I am going for speed runs.
so, how fast would it go with a 3000kv?

Well here's a video of our race this past weekend with 21.5 motors. If you watch closely even the well handling cars are a bit scary on the long stretch of our track. I wouldn't want to put any more power into the car than it has with a 21.5 on our track. Now in a big open parking lot for straight line runs more power will be fine...provided you have enough traction. Even then I think a 13.5 is going to be on the edge.
