I will by Quark, just because it is different for around half the price of 125B, because IC's now days are getting cheaper and they already good for CE and RoHS.

As for design flaws, I can pass them couple thoughts if they contact. But in general I am not happy with pcb layout they have, from heat transfer stand point. Enclosure (case) can be improved but pcb is the culprit. Also, make it water proof, so simple with silicon wires...

When I first saw the 125B, I was a little freaked out as the positive and negative power wires came out ot the same place. When it burned and I opened the case to see what had gone wrong, you could see that the problem might have started there. I like ESC that places the power wires at the corners. Like the ones I'm having made and the one Artur made. If my controllers gets done soon, it will be the first of it's kind just for cars. That would be too funny considering that the big players all have HV, but they are for aircraft. I have no clue why we haven't seen a HV controller for cars yet. To me all this companies are too greedy and only thinking about what the returns might be. Off topic: A lot of people are pissed of at a few Asian companies for pricing the products right (In my opinion). You can buy hard cased 3200mAh 7.4v lipo for $34.99 (used to be $49 which still is cheap). They use the same concept I use and when my controllers gets done, I will also use the same concept.

Hi, Griffin.
I think you are right on the price of 125B going down in the future. Even though I didn't hear a clear answer to my question from Sky-Tech, I think that they have been affected by Mamba Monster Maxx when I heard they said "yes, we have seen it." The company didn't have a lot of workers in the office when I visited the company. Maybe, it was due to some people going on leave after a long business trips. (They had been gone for almost 2 weeks for participating in a trade show and racing events) So the guy I talked to seemed to know a lot about the company's future plan. Anyway, if you take a look at the SSB-mk3 (mk1 and mk2) the case design is much better. And when I called them today to ask about my SSB-mk2 being fixed, the guy said that they have changed the CPU and did other upgrades for my ESC for free. If you let me know about your thoughts on possible upgrades to Monster 125B, I will let them know about it.

Thank you. ^^

what exaclty is a 'super hv esc'?
lets say it would be able to deal with 200A constant and whatever burst and up to 8-10s lipos... good heatsink bolt on.. or watercooling ready ... i guess i would easily pay up to 400$.

I wouldn't pay anything more then the price of a mamba monster. It's just silly to pay anything more for the same electronics and packaging

I agree with you Lutach. Current market wants everything smaller, faster, more powerfull and better. Powerfull and smaller don't go well together.

Amen! I would MUCH rather have a larger ESC that runs cooler than an itty-bitty one that is thermally challenged...

Double Amen to that. If Ron and I can stuff a Schulze in our 1/8 scale trucks, anything manufacturers make will fit. You guys, I'm apoligizing again as I forgot to mention MGM and BK to the HV companies that makes a car controller.

I am using the 125b in my RC8 and I really like it. So far, no major heat problems yet, but it does get warmer than I would like after about 15-20 minutes on a track. I would buy that new ESC if it doesn't have heat problems.

Personally, I rather pay for performance. I would gladly pay a couple hundred bucks for an ESC that works flawlessly. Let me repeat... FLAWLESS. In fact, I wouldn't think twice about dropping 400-500 bucks for an esc that I know will never have heat problems, will never cog, will never have ghost in the machine problems like full braking while the car is in neutral and any other problem these manufacturers can't seem to figure out.

My only hope is that the rumored MMM will solve all these issues. I have a lot of confidence in them given that we can pretty reliably use the standard MM without too many issues, so I would hope they can make a purpose built ESC for 1/8's that doesn't have any issues.

I would add that customer service and support for me is worth at least 50% of the asking price. ONLY from what i hear about MGM (lots of help from Mike but then back to Europe), Schulze (fire and limited warrantee) and Quark (thermalling, mod hacks and ok support) has left me waiting a year for the MM.

I've burnt 3MM in the mean time (paying for 2 as they were in 8th conversions on 4s) but each time turnaround and service was great.

I am looking to buy another HV controller as a back up to my HV-110 but at this point don't know what else to get other then a HV110 again. I wish the MMM would have been an HV model, that would have eliminated my confusion. At this point I think I'm going to order the TURNIGY Sentilon 100A and 1 of the Himodel 200A controllers which both together is still cheaper then 1 HV CC controller. The Himodel says it will handle up to only 7S though, but I will try it anyhow. I just recieved my 2nd Neu motor for my E-maxx, I think this motor is more suited for high speed runs since its only 1860KV's. The 1521 1.5D should lay down some big power and only has a 95amp draw. I had a 1527 1D and the amp draw was WAY to high (200A). Just hope one of these ESC's will handle it.

They are very good about it normally, no questions asked most of the time. I think there is a phone number on their website somewhere...
