200A, 14S lipos ESC to come!!!

Lutach, ESC is automatic Cell Detection/Cut off... So that's a failed unit....? that sucks man... I saw this thread come back, and I was hoping everything was a go... LOL

This is from a different place. The HV ones will hopefully get done some time next year and I'm really about it. This one is the 120A version and they have a 90A and a 60A, but the 60A will be sensorless only and the other 2 will be sensored or sensorless. I'm reading the e-mail now and it claims the 120A, 90A and 60A can handle 2-4S lipos, but I should only use 2S. I'll go 3S and see if the controller handles that. I assume it will auto detect the cells and the cutoff can be set with the program box. I don't want to say much until the controller is here, which will be tomorrow (maybe). What should I do to the UPS driver though ?

Tracked the package and it says, "12/17/2007 8:41 P.M. THE PACKAGE IS DELAYED DUE TO EMERGENCY CONDITIONS BEYOND UPS' CONTROL
12/17/2007 1:15 A.M. OUT FOR DELIVERY".

I guess the driver wanted to go home!

I finally got it. Here are the specs:

120A Continuous (720A burst)
0.0003ohm
39g (without wires)
Sensored/Sensoreless Brushless Motor and Brushed Motor
Brushless Motor with 2.5T and up
2-4 cell lipo Brushless/2 cell lipo Brushed
BEC 6V/2A
Fan
Low Voltage, Over-Heat, Signal Loss and Locked Rotor Protection
The Brake is Proportional ABS

Now the program box has the following:

1. Running Mode:
(1) Forward/Brake
(2) Forward/Brake/Reverse
2. Drag Brake Force:
(1) 0%
(2) 5%
(3) 10%
(4) 15%
(5) 20%
(6) 25%
(7) 30%
(8) 40%
3. Low Voltage Cut-Off:
(1) None
(2) 2.6V/Cell
(3) 2.8V/Cell
(4) 3.0V/Cell
(5) 3.2V/Cell
(6) 3.4V/Cell
4. Start Mode:
(1) Soft
(2) Normal
(3) Aggressive
(4) Very Aggressive
5. Brake Force:
(1) 25%
(2) 50%
(3) 75%
(4) 100%
6. Reverse Force:
(1) 25%
(2) 50%
(3) 75%
(4) 100%
7. Initial Brake Force:
(1) Drag Brake Force
(2) 0
(3) 20%
(4) 40%
8. Neutral Range:
(1) 6%
(2) 9%
(3) 12%
9. Timing:
(1) 0°
(2) 3.75°
(3) 7.5°
(4) 11.25°
(5) 15°
(6) 18.75°
(7) 22.5°
(8)26.25°
10. Motor Type:
(1) Brushless Motor
(2) Brushed Motor With Reverse
(3) Brushed Motor Forward/Brake Only
11. Over-Heat Protection:
(1) 95°C
(2) Disabled

All of it looks very impressive. The only problem I see is with the fan. It is rated for up to 7.2V and the slot to put the fan is connected directly to the battery, so you can only use 6 cell NiCD or 2 cell Lipo. I will add a connector to have it run from the 3rd channel. I will do the initial tests with 3 cell lipo in my TC3. I can't take pics now, because I have no clue where my camera is.
