I think they're going to be disappointed if they think they're going to make any sort of major sales in the 2S - 4S category. I think that's pretty much locked up by castle, IMHO. Personally I think the opportunities start in the 5S and up category. The ones that are available for that voltage level are downright pricy. I'd love to run big cell counts, but I really don't feel like dropping $400 on an ESC, if ya know what I mean. Seeing the OEMRC sentilion 12S controller for under $100 gives me hope. Too bad it's not usable in cars (well, you can with mechanical brakes, but I don't have a rig with those).

The one you've got looks pretty cool. I love the external programming box, much better than dragging a darn laptop to the track.

I look forward to further developments!

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.

Features look great. I like the timing, Locked Rotor Protection and the overheat protection feature. When can I test one in my dragracing rustler..hehhehehe. I'm pushing/killing my mamba esc with 6s1p A123 at the moment.

Let me see how this one handles in my TC3 and I'll even try it in the truck with the Neu 1521.

Just give 'em a link to RCM and show them how much demand there is for a reasonable priced HV unit, and how non-existant peoples options are. Anyway, that unit you have there has some very nice features, and its a step in the right direction at any rate...

I told them a few times to make an HV version. I will keep buggin' them to see if one can be made. I like the features and I will have to see if they are all working when I put it in my TC3.

I was able to run the ESC today for a little bit and it is very nice. I noticed the PCB is almost twice the thickness of the Mamba Max. It fits in my TC3 better then the Mamba Max. It is absolutly smoother and programming is a blast with the program box. The ESC got a little wet, but it did not affect the way it put the power down. The brakes are just awesome and smooth and reverse is also nice. I still can't find my camera to take pictures of this controller next to the Mamba Max. I like my Mamba Max a lot, but this new controller is much better and I'm not hyping it up. The Mamba Max off the line hesitates a bit with the N80 motor and this controller just goes.

snellemin · 12.20.2007, 06:18 PM

Have you raised the startup power in the mamba esc with the N80(7800kv) motor?

Yes, the Mamba's starting power is at high. The hesitation that I'm talking about is really small and only happens when full throttle from a dead stop. Also, the other controller's heat sink after I was done speeding up and down the street for a few minutes was still cold with the fan disconnected.

snellemin · 12.20.2007, 06:37 PM

Have you tried reducing the punch control in combination w/high start power?

Sounds like you have a really nice ESC man. I seriously need something like that for my dragster.

I have the punch control at 40%. The Mamba is good, I'm not complaining at all, but I have found something better, I hate to say it. The start up on this controller is amazing. The only down side is the fan which only works with 2S lipos from the connector in the ESC, but you can hook it up to the third channel or a separate BEC. I was told the BEC in the ESC only works with 2S lipos as well, but I had it going with 3S for a few minutes and it worked fine. I'm still waiting for an answer from the folks who made it to see if they have any stock.
