Bolted on a 15t 32p pinion
I had to drill and tap the motor end to match the spacing of the gb

Nice...Those specs are very close to the BaneBots motors....might have a touch more pull.

What watt controller are you using?




EDIT..... :o :shock: ... I just found a online conversion ...The Banebots motors that I am using stall at a little over 1200 mn-m. These are sick!....... Acorrding to your specs they should stall at 2116 mn-m! :shock: :shock:

:lol: :P :o :? :shock: :D :lol: :P TWITCH :? :P :o TWITCH TWITCH :shock: :? :lol: :lol:


You might need a bigger controller....or a boost button. There is a converter on the scooter site in the FAQs that helps you figure out required watts.


Cant wait!

I know the Banebots motors together with the stock 550 in the front require 1100 something to get the full potential out of them. Thats why I went to 2 controllers. Recently I found a 1000 watt 24 volt controller. (after I bought my stuff....figures) I think it was at Monster Scooter parts....not sure.


Where did you get those....and what did you pay?

A good friend works at a tool repair shop, he threw new bushings and brushes in and i got em for 20. They can be bought new here http://www.google.com/url?sa=t&source=w ... MCQQJr1HnQ

but they are EXPENSIVE!
I ordered 4 lbd-14 last time I got stuff from tnc so I can throw 2 at it to see how it does.
Id love to buy a kelly controller

I'd start out with the single one you have. Those motors may be so powerful that they do more than the job at about 25% of rated output. You'd never hurt a motor that way.

I bet these would work great in a Gaucho. Can't wait to see your results.

def. i dont wanna have to buy one new. i'll have the power, hopefully i can find the balance between good traction and making in your words a "gearbox blender" :)

"gearbox blender".......I like that one. It's not an insult, It's a goal.

"gearbox blender"....Thats when you end up with inside parts on the outside and outside parts on the inside. Back in my racing days it was known as "oil pan failure"......That's when the oil pain fails to contain the "inside parts" LOL :lol: :lol: :lol:

Now if somebody can figure out the pitch for the gaucho pinions......

Big time success tonight. Got it all bolted up and wired in. The brute force was a hill climbing machine. We had two kids on it and one in a wagon behind, I felt the motors after ten minutes of hard riding and they were barely warm. Top speed is down but worrying about stalling out is gone. It was def an improvement

Now to hunt for used drills on the cheap. :P You see it all the time. Just like PW. Giving it away because the battery has gone bad and it's cheaper to buy a new drill with a new battery sometimes. :mrgreen:

One controller is gonna be just fine. Its at the point i'm nervous about the gb being able to hold up. the monster traction tires are the most grip i want this thing to have. I didn't put the fan back on yet so i could get to both motors( I cut a huge hole in the top of the module) and i could put my hand on the motors right after they got done riding and it wasn't even luke warm. we had two kids on it, pulling a wagon with a kid in it and it didn't even slow down

I did find the part number for the motor cross references to black and Decker 18v drill motors also. I would imagine that those would draw a much lower resale price used, and I doubt people rush out to buy new b&d batteries when they wear out.

Here's the boy beating up on the brute force. This is the dewalt motors on the gb with the bearings running 24v esc with twist throttle. He runs it hard :D

Nice! I think you may have come up with a "reliable" 24 volt set up. Keep us posted on the durability.

Check out the mabuchi part number on the motor. http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... K:MEWAX:IT :ugeek: There has to be a vendor that sells those motors you used. We just have to find em'. Here is the replacement motors for the ones you have: http://cgi.ebay.com/DeWalt-18-Volt-18V- ... 0198426151. It has begun. :mrgreen: http://cgi.ebay.com/Dewalt-393111-01-18 ... 20bb118cf5
