Next time you want to ridicule someone for doing something outside the box (that's [email protected]$$ btw) maybe you should use spell check so you don't look like even more of a jerk!

Need to run 14-16cells (or lipo equiv) to generate rpm so you'd have some speed.
Yeah. Because of this, I'd probably try to get a drill with the lowest voltage you can. A weaker drill at full voltage is probably stronger than a more powerful drill at half voltage.

so maybe the cordless screwdriver that is 7.2 volt is better for a 10t? or is that too little and pointless?

That seems a bit small. Maybe use a 12V drill. Also, not sure if you meant this, but cordless screwdrivers are different from cordless drills I think. Cordless screwdrivers are meant just to put screws into stuff and are a different shape. I have one of those and they're very weak, even with the gearbox. Sorry if this isn't what you meant but I want to make sure we're not confused
Anyway, I suggest that you use something like a 12V cordless drill. Depends on what battery you're using. If you plan on using something like a 3S LiPo, then you could go to like 14.4V. I'm not using an exact science and these are all educated guesses.

I just pulled apart an old Craftsman 9.6v cordless drill that I had laying in the bottom of my tool box. Hasn't worked in years because of bad batteries.

The motor is basically the same size in diameter as 1/8th scale electric motor. I hooked up a Nimh pack to it real quick and it spins very fast. I'm definately going to try this thing out in my E-Maxx at some point. Even if it ends up being somewhat slow, it will be a torque monster.

Good luck! I recently took apart a 14.4V drill for the same reason; It's motor is the same size as a 1/10 scale (but longer). Its pressed gear has the wrong pitch, so I'll have to use a pinion puller to take it off, then grind a flat spot onto the shaft for the set screw on the new pinion.

Yeah, already realized that. No biggie. This project won't cost me anything but time, assuming I don't break something in the process. LOL

I'm going to have to get creative on pulling off that pressed on pinion. Maybe just set my vice to hold the pinion and hammer out the shaft. LOL. We'll see.

Questions??

Our local hobby shop built a few E-Maxxs for a local Dewalt supplier a couple of years ago. We used the Novak esc that came with the truck. I remember the first time we powered one up,instant wheelie-flip

Hope this comes to fruition for you, I have seen some pretty amazing videos with folks using the Dewalt motor. Whodda thunk you could stick a drill motor in a truck and it would damn near walk on water

If you've got a dremel, use a cutting wheel and just cut it off. Wrap the motor up in a ziploc bag and stick the shaft thru the bag and tape around the hole where it came out so none of the grit can get in the motor while you're cutting.

You want a nice motor go to kershawdesigns.com they have some motors with a lot of torque and they are waterproof. just a suggestion.
