Yep. Common with the 4 pin setup. That's why most guys go with the belt drive or the square drive setup.

I have to disagree Deluge, it was very common with the square drive setup...(see all the old posts I linked) and I haven't heard as much with guys running the newer 4 pin setup.
 
Thanks for the info everyone. I'm going to take the suggestion and keep the gears running as long as possible. Meanwhile I'll be hunting around for belt (or chain) options. The current one is great but the gearing is too high for electric.

I need to educate myself about belts, pitch, pulleys, etc. and of course figure out where to get this stuff. I'm sure I'll have to take some parts and modify them to fit so it won't be a quick fix.

I can let you take a look at the belt drive kit. I am looking into some local companies for pulley manufacturing. It would be very easy to gear it down.

Shoot, I wish this was about 30mins earlier. I just ordered some pulleys from New York. If I come up w/ something that works, you are more than welcomed to it.

I just ordered up some aluminum pulleys. I ordered 12t, 15t, 22t, and 24t. They have a 6mm bore that'll increase to 8mm. I didn't order a tensioner b/c I need to figure that one out when things are coming together. I also ordered some belts from 9.8"-12.2" in circumference. I made some measurements; I hope my math is somewhat close. The belts are 15mm wide w/ a 5mm pitch and a breaking force of over 900 lbf/in (to be honest I have no idea if that's strong enough). This should be a learning experience.I don't plan on getting this done real soon but I wanted to make some progress.

I quoted this from other thread, Should probably be here...lol

Sure to snap a couple quick pics for us all to have a look.

Where did you end up ordering them from?
 
I felt like since the other thread was specific to the belt drive and this one is specific to using an electric motor, I put it over there. But I can see how things are starting to melt together.

Anyway, I always thought I had 3 x 25t and 1 x 35t gears. It turns out I have 1 x 24t, 1 x 25t, 1 x 26t, and 1 x 35t gear. And when I put them on the gear plate correctly (i.e. 25/35 -> 24/26) they don't bind so much and my ratio is NOT 1.4 but rather 1.51. Did everyone else know that and I'm just finally catching up, lol?
 
That's a new one for me. I know the MT comes with a 35 & 3x25

The XB and XSC come with a 31,29,26,24 I did not realize the 4 pins came in that configuration also.

You are correct if you run 24-26 for the C & D gear you drop the ratio a bit more.

I guess mine did come with 31, 29, 26, 24 but you kindly gave me your 25, 35.

If you get a belt drive to work on your setup you will be happy ditch the gears also. LOL
 
You are right, there's a list of things for me to do before getting to the track again which will take priority over the belt drive:

1. heat sink/fan for the motor

2. capacitor bank for the esc

3. get (and rewire) computer power supply to charge the batteries

4. reconfigure some 2s packs to 6s

5. loctite gear pins
 
Thanks, I think I have one of those. That could save me a bunch of time. I think mine is from a 4465 motor, is that what yours is from?
 
It's not actually from any motor I had. I ordered it to see if I could make it fit the 5692. But it is designed for that size of motor. It was about 45mm across before I bent it to about 55mm.
 
I agree its nasty to pay a cars worth on a esc but we still come in cheaper than a fg comp or a losi with a after market motor if we run a redcat. Brakes add 20% to 30% more run time so says mcd. Most people would trade the slight advantage of a esc braking stopping distance to get more run time. So I would also like to see brakes on 1/5th scalers as it really does help get that run time. I'm sure some one in the industry is taking notes off your build:)
