A new toy for me!

I have some ployquest 12c 3600 cells (8 of them) and as long as they fit I will make up a pair of 3600 4s packs. It will be nice to have a sturdy tranny and slipper! Lets see how this proposed setup works and I may have to give it a try!

Any idea what you think average and max current draw with this motor would be? Mainly cause I have a mgm 90amp 4 cell esc that needs a home, and the mgm escs will run an outrunner IIRC.

Soon, I will have a quantity of Lipo packs made from 5000mah 20C cells that have the 45mm x 145mm footprint. I plan on keeping 2 - 2S packs and 2 - 3S packs.

They will all fit the stock battery compartment.

This will allow me to run 4S, 5S, or 6S configurations. Motor temps will show me the way. I might play around with this. I believe optional battery hold downs are going to be available for this to allow for larger packs. Have you heard anything on this?

Your battery setup should work well. 86 amps continous and 7200mah should make for some nice runtime.

About the amp draw, I'm not sure on this one yet. Actually, you have a better idea of how the 2826 performs with the Redcat. Tell me, how does it do? How many watts do you think it's capable of? You don't have the cooler though right? Here's this same setup with your AXI motor. It would perform pretty good too IMO. Using a motor of less kv, just means it's going to accelerate that much harder.

Effective KV Value: 760

It's tricky business with Direct Drive trying to match the "power band" of the motor to the diff gearing and tire size.

I'm really excited about this setup because we have the gearing to work with to keep the motor in that "sweet spot".
