Outrunner to diff in SCX10

[TexasSP]

The front is overdriven on purpose and will stay that way. It eliminates torques twist, eliminates rear bounce when climbing, and helps with downhill driving. I am not so much worried about finding KV as much as finding the correct outrunner size as I am not as familiar with those.

It is extremely common for scale trucks and crawlers to overdrive the front and their never was nor will be a center diff as that would sacrifice performance.

Hi TexasSP,

I got your PM. Interesting thing you are working on putting together here.

When I first looked at the truck, I thought, this is going to be easy. But then I realized you intend to eliminate the transmission.

If you were going to retain the transmission, I would go with an outrunner like this one.:

I'm pretty sure this one is 8 pole. Tremendous Amount of Torque. I've ran this in the E Revo and in the E maxx. It is 550 size. 37mm X 56mm

If you want to consider trying this motor with your transmission. Gear it low, put it on 6S, and engage 100% drag Brake on your MMPro for the ultimate crawling experience. I feel it would crawl great, plus produce some good top speed when flat running.

Now to eliminate the transmission and recommend a good motor, there are a few things I need to know.

I need the diameter and length of the output shaft on the transmission. We gotta try to match something up with that data.

Then allow some length for your motor mount.

Interesting setup and idea. I look forward to seeing how this evolves.

Hmmmmm........battery? Your compartment will house 1 6-cell nimh pack?

I wouldn't rule out 6S operation. It will be a little taller than a 6-cell nimh pack, but I would consider something like a 6S 2650mah lipo.

Linc is right. Go low on the kv and up the voltage for this setup.
