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

[snellemin]

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'm also going to have some Brushless ESC for 1/18, 1/16 and 1/14 scale. This little guy has the following Specs:

Weight: 23g (including leads)

Features:

Proportional forward, brake and reverse
Proportional control of starting torque by throttle trigger – the starting
torque can be tremendous high or incredibly low
Extremely smooth startup and low speed operations
Programmable throttle curve, acceleration rate, motor timing, low
battery cutoff voltage, reverse power limit and drag brake strength

Option 7 (Nixx Not applicable, A123 7S (14.0 V), Lixx (Low) Not applicable, Lixx (Medium) Not applicable, Lixx (High) Not applicable

7: Low Battery Cutoff Method:
Option 1 (Partial Cutoff)
Option 2 (Default) (Full Cutoff)

8: Reverse Power Limit:
Option 1 (25%)
Option 2 (50%)
Option 3 (75%)
Option 4 (Default) (100%)

Item 9: Drag Brake Strength
Works with: 4 (Option 1-4) 5 (Option 5)
Option 1 (Default) 0% 0%
Option 2 5% 12%
Option 3 10% 25%
Option 4 15% 37%
Option 5 20% 50%
Option 6 25% 62%
Option 7 30% 75%
Option 8 35% 87%
Option 9 40% 100%

This little controller is the only one I know of that has a Battery setting for the A123 style batteries with a 2.0V cut off and it has a setting for crawlers.

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]

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.

what i think would be cool is
one of these

your esc, lutach.

2 of these

and this (maybe, 6s might burn it up, but for $19, who cares )

Slight bit of a necropost, but I stumbled across this whilst looking on fleebay:

Speedpassion esc

and their main site:Clicky

One or both of those escs look rather familiar to me...

You should check out the guys at rctech.net. They are flaming and would probably choke me to death. Speed Passion is a line from King Golden which is a distributor. I have the controller from the factory that made Speed Passion, but the factory's has beeter specs. I think UH www.hobbycity.com will carry the same model I have. I'm still trying to get pricing from the factory, but the delay is incredible.

Problem is the 3S lipo limit sucks

For Speed Passion yes, mine handles 4S lipos.

I saw that in the SP thread lutach

You really got flamed lol, I was laughing so hard, those guys really want what everyone else has

They actually messed up in this forum: http://www.radiocontrolzone.com/showthread.php?t=244134. Adam actually said the SP GT pictured was the 60A Feigao, which is not true. I hope to get prices soon and I hope hobbycity.com can get them as well and I'll see what those guys who bought the GT will say. It's funny how Shawn started making up specs when he was under the gun. Those guys have no clue what timing means and I've seen them saying if you advance the time in a brushless, the motor will be faster. I wish my motors would go faster if I change the timing. If I'm wrong, please correct me.
