The only trouble with a VXL combo is that the ESC doesn't give you much in the way of adjustability compared to the MM. And the MM could be used up to 4s (with BEC disabled) so future upgrades could be as simple as a new motor (XL, Neu, Medusa 60/70mm, etc). Could also go with a Novak system. Either will work though for the speeds he wants.

I just thought it was funny everyone was throwing around ideas to use the larger motors when they simply are not needed. And just spinning a motor slowly has two disadvantages: 1) as noted, there is less efficiency at less than WOT settings, and 2) there may be cogging as the motor may not be spinning fast enough to get a good rpm signal at the speeds we are talking about. No, I'd say get a combo that will allow the motor to spin fast enough and just gear down, or use an outrunner.

Basicly I want to get insane run time. I dont want to ever charge my RC CAR again.. just kidding.

I think instead of doing this to my E MAXX am going to convert my Losi LST2 Monster Truck.

Here are the packs im going to use, they are huge! I would like to stack about 6 of them on top of my lst2.

My plan for right now is to eliminate the whole transmition and run a direct drive low kv motor.

That way I would have a nice flat space on top of the lst2 to stack 6 cells for a nice 60,000 mah :P!!!

# Voltage: 7.4v
# Battery capacity:10000mah
# Discharge rate: 12C
# Size: 178mm (L) x 98mm (W) x 11mm ( thick)
# Weight: 530g
# Quantity：2

If I run this at 7.4v then I would have 60,000mAh @ 7.4v 720AMP<<<< Con LOL!!!!

At 60,000mAh the pack would be

7 Inch Long.
3.8 Inch Wide.
2.5 Inch High.

A very nice fit for top of the LST2, as long as I can mount the motor in the center and under. Im still trying to figure out if this will even work. I need to learn more about electricity...
All I have to do is find a nice low kv motor. Im just wondering if they make low kv motors that can run, on 7.4v. Also I am wondering how the Mamba Monster would react to a set up like this.
