It is not so much the dewalt motors. It is the amount of watts claimed to
draw verses the amount it is accually drawing. You admit that your system
was in the 1400 watts range. Not 775 or so. You said mid 40s the other says 50.

I am not zeropointbug. I can not speak to his claims. I was talking about my experiences.

With 66 spur and 22 pinion 4s lipos on a 7xl my truck does 40mph
The same setup on 6s did 50mph but it was over the limits of the motor and was only done for a couple runs. Not to mention the fact it was extremely hard to control.
I got my speeds from a bushnell radar gun.
When I checked it out on Brian Gs' speed calculator it was very close. I guess I could have saved $79 and just trusted his calculations but were is the fun in that?

Your story adds up. I say yes it is very possible. I just have questions on other. Either it ran 50 on more wattage or less on 775 watts. :002:
Anything is possible though.

Coolhandcountry You say the titan is rated for 175 watts? On Kershaw Designs he says the Titan puts out 129 watts on 14.4 volts. That might explain why i am able to get to 50 mph on "750watts", so maybe the dewalt setup is putting out something more like 1100 watts or more? Maybe his testing rig is messed, or he just doesn't know what he is doing...
Also, he says 80% peak efficiency, but i don't know what power output that is at? (seems reasonable)

And ppl DO under estimate the 820 motors, they capable of very high power. Apparently you can run them on 18 cells no problem. "600 watts" from one motor... in his watt ratings.
