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.

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.

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.

snellemin · 12.20.2007, 08:58 PM

sweet deal man. The mamba does great with low kv motors, but I have the same issue like you when I use my 7800kV LRP.

I like the high cell counts... when are you expecting this?

Aqwut the above ESC is for the small RCs. The factory only has 30 of them and I'm thinking of getting them all, but I don't know how many people would actually want one. If I can get 20 people interested, I'll bring the 30 units in.

aqwut · 12.27.2007, 12:51 AM

yeah... those are some good escs according to the specs... that's a lot of power for a small scale RC.. but it's awesome to have a 1/18th scale rc running 22.2 volts...

The small ESC says to use up to 3S lipos with BEC and to desable it for 4-6S lipos. Man I tried this little monster with a 5S 3850mAh TP to see if it could handle it. Well it does and the Mamba 8000 motor's shaft broke. This will be the ESC I will use in a micro to try and set s speed record. I might buy a Recoil to do this.

i had a recoil running a wraith7k/quark 33a. i loved how that car handled the power. i miss it now that it hit ebay to fund other projects. i think i seen a pro version coming out so i might have to get one of those again to fill the loss i feel.

I own a few Quark 33A and 22A and they are good, but this 40A controller goes a step further with the 6S lipo and 7S A123 capability.
