<span class="Apple-style-span" style="font-family: verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif; font-size: 13px; ">I just installed a Novak Ballistic 3S 8.5T 5000KV brushless system in my TB-03D. It is a little slow at start up and I thought it was suppose to be like that.

I played with my Sprint 2 recently and it has a Orion Orbital 13T Modified Motor and Tazer 12T ESC and I had a blast. Smooth, torque, awesome. A dream to drift/race with.

I read the manuel and it said you must change the pinion gear or I'll have a slow sloppy start and it'll run hotter(Like it does now). It gave some pinion teeth numbers though. Not sure what to choose or where to get it.

I don't have to change the Spur Gear right? What pinion gear for my motor should I get for the TB-03D to optimize it? Where to get it?


Also, after playing with my Sprint 2 I almost went back to brush motors. I am new to Brushless Systems still. The Orion was awesome, I want my TB-03D to have that feeling of torque, smoothness and not running hot. Also my brush has 0 glitches.

Let me hear your thoughts.</span>

yes you will need a different pinion. spur gear change is unnessacary I also have the TBO3D very nice car and very fast with the correct gearing to find out what pinion you need you need to check the instructions and recommendations on the motor... there is also a site that will work it out for you but i forget it... does anyone know?

Read this post, it also has a roll out calculator in it to help with pinion gear selection.

If I did the calculations right on the calculator. Getting closest to 0. Rollout ration 4.5.<div></div><div>64T Spur</div><div>22T Pinion</div><div>2.4 Transmission Ration</div><div>2.5" Tire Diameter(I use HPI T-Drifts on HPI 26mm Rims.)</div><div></div><div>I should be using a Tamiya 10T Pinion. It's even on the manuel as a suggestion to use 10T-15T on the Novak Ballistic 3S 8.5T Brushless System. Hopefully I got this right and I wont burn anything out or come up with less power. Let me know you thoughts guys.

Although I looked at 10T Tamiya Pinion gear and it looked to small. WHat would you guys recommend?</div>

My recommendation is to get multiple gears and try them. Find a safe compromise between power and temps.
