have out there that might be good for the Grant build

Advice from Alliance East.
When in doubt, hire the gnome. The price is right. See you in a few.

Thanks for the input guys.
Doug: I gradually increased the track tension to where there is little
slippage, although the rolling resistance of the tracks seems high to
me, but I don't have anything to compare it to. So at the current
track tension, the problem manifests as mostly stalling, as Fran
Also, 10 AWG is "ok" from the speed controller to each motor, but you
should run separate lines from the battery/fuses/switch to the speed
controller channels because of the combined current draw of the EVs.

Henry, when you try to trun in grass, is there slippage anywhere ? Do the belts
in the transmission slip ? Does the track slip on the drive wheel ?
Or does is simply seem like the motors don't have enough umph to turn the tank
? Do you know how old your battery is ?

Speed kills. The gear ratio of 6:1 is too low, significantly dropping
the amount of torque to the drive shaft. At that ratio, the tank will
have problems starting from a dead stop, climbing up things and turning.
In all those cases, the EVs will bog down, draw excessive current and
basically
1) Gear ratio: 6:1
2) Drive wheel diam: 4.25 inch
3) Speed control: Robot Solutions, 160 A (I think)
4) Wire gauge: 10 AWG
5) Motor age: Don't know
And the treads are square, not beveled.
Keep in mind, I'm not the builder of the tank, nor was the previous
owner, so I'm just finding out what its q
T005 ran EVW's at 12v with no turning issues. Gear reduction was 9:1
and it had a friction drive. Provide the data Frank requested and
we'll work through this.

The shape of your treads could be the problem. If the sides are square, they
will dig in when you try to turn. If you can angle the sides of the treads,
that could help.

Yes, we ran some of tanks on EVs at 12v, at heavier weights, so let's
explore all the parameters to help diagnose the problem:
1) What gear ratio are you using between the motors and drive shaft?
2) What's the diameter of your friction drive wheels?
3) What type of speed control, if any, are y
Yeah, I'm definitely short of torque, but I had the impression that
others were able to run EVW's at 12V OK. Probably not the case eh?

Go to 24V, you're short on torque.

I've been testing my tank and the turning performance is poor. The
tanks has EV Warrior motors with two stages of gears, friction drive
wheels, and TTS tracks with molded treads. A pretty standard design
that seems to work for other folks' tanks. It weighs around 90 lbs,
currently with no turret an
