1/10 Ruckus 2wd

[bbbv4711]

I am new to the hobby, so sorry for the long post. I bought my son a Traxxas 2wd Stampede VXL, to be able to have father/son time I decided to get a Ruckus 2wd. The Ruckus is the brushed with lipo, I knew I would be upgrading as things broke. 1st was the driveshafts upgraded to Hot Racing SECT288x06, then I picked up a venom 25C 2S 5000mAh. The next run I smoked the ESC/Motor. So I picked up a metal gear set and Hot Racing steel spur gear(48P 87T) and Maclan diamondback 80a esc/MX540 4000kv combo. I believe the original pinion it 17t, which I am using with the new setup.
After searching this site and watching videos I changed the gears and installed the esc/motor combo. 1st run was not impressed, seems like slipper was too loose so I tightened 1/2 a turn. This was better, but maybe just a little better than the stock brushed setup. I do know I need to buy a programmer for the ESC, apparently it comes new with reverse locked out.
Any suggestions or comments to get the most out of the esc/motor setup? Also what does the numbers represent on gears? Like the spur is 48P 87T, I assume the 87T is teeth what is the 48P?

48P is the gear pitch, indicating how close the teeth are together. It has to match the pinion obviously. With a steel spur you shouldn't have any problems; some people upgrade to a 32P plastic setup instead when they ruin the spur. Smaller pitch = less teeth = bigger, sturdier teeth.

I don't know your specific motor, but I think it should have a lot more torque than the stock brushed motor, so you could change to a larger pinion and it should give you more top end and still accelerate well enough. Only one way to find out Keep an eye on motor temps though. An IR temp gun is like $12, cheap insurance. Hottest temps for me are when running in tall grass.

Yes, the "T" is how many teeth are on the gear. The "P", in a very simplified description, tells you how big the teeth are. Diametral pitch is how many teeth can fit on a gear with 1" pitch diameter. Circular pitch is the distance between a location on the face of one tooth in relation to the same location on an adjacent tooth.

Thanks for the replies. I will pick up a pack of pinions and try different sizes. I do have a IR temp gun, so will watch temps close.

I have a 3900KV in my Ruckus. On 2S you should be able to comfortably use a 24T pinion with the 87T spur. If you watch the temps, you can run it on 3S. It will be insane, but a lot of fun.

I did try a 20T along with setting up the esc with the prolink from maclan. Huge difference......The motor temps are running 130-140F on 2S. I am going to play with some different setups. With the extra power I am seeing that better shocks/oil and steering parts are next.
