My favorites for the money and features are by far the sp silver arrow v2 and the xerun sensored 150amp blue esc. They both have great features, rock solid durability and are highly adjustable and reliable.

BTW, I am having really good luck with the ESC in my Thunder Tiger EB4 G3 Buggy, it's made by Hobbywing, but branded as ACE RC, it's a 80 amp version with a 2000kv motor, I'm running (2) Gens Ace 5000mah 50c packs in series. The ESC is nice and smooth, very responsive and very powerful. No problems with it at all. If it ever does crap out, I'll upgrade it to the 150a HW version.

I also have had great luck with the speed passion silver arrow esc. However, I thinking of giving the Hobbywing 150a a try. I also have been looking at the new Tekin RX-8 rated at 220a. Can someone explain the rated amps on these esc's? What's the benefit of 220a over 150a?

+1, great ESC, have it in my car, recently scored 1&2 at our 1:8 nationals

I also like the silver arrow. I'm thinking of giving the hobbywing 150 a try. Would I notice any power increase by switching to the Hobbywing?

If your upgrading to a 150a from a lower amp esc, then yes, you should notice a difference, more punch, more power. It is noticable bewteen the HW 80a and 150a big time.

i'm just reading through this thread not yet all the way through but there has already been a few references to the size of the Hobbywing 120 amp esc. I have a rx8 in my mugen but just last weekend was looking at a guys setups with 2 of the hobbywing 120 amp esc's. They were A lot bigger side by side.

My mugen mbx6 eco(not a lot of space for the esc) can fit the rx8 perfectly. Not hanging off the back like the hobby wing would do(by a lot i must add). I had a Silver arrow 2(speed passion esc) in it before the rx8 and it ran good till i got it wet. I will Say the rx8 is much smoother then the speedpassion esc and have alot more "on-board" settings then the speedpassions "off board" setting. (silver arrow 2 is probably similar in size to the hobbywing from what i have seen)

Still haven't raced the rx8 much but i love the software and smoothness of the esc. So far hasnt ran over 140 Degrees with a t8 motor in it.


I would also like to say that after reading everyone stating there complaints about the 1/8 esc's i would like to remind people how fast and far they have come in r/c technology. I just got back in since racing in 2007(brushless had just come out around then so i race brushed for the years i did race) and since 2007 things have changed dramatically. Everything has chagned so much that its almost like starting all over again as far as learning the technology and how to use it. A lot of the burn up esc's and failed esc's are most likely from user abuse. Weather it be hard bashing or a bad set-up. However with that said stating what you are looking for in a esc on here does help the people making the product understand our wants and needs. Glad to see for the most part all negative comments are being given as constructive criticism rather then just bashing a company. Just my 2 cents

I had the Xerun 80a esc, and now have the 150a esc. I used the same motors with both. I noticed no difference. Both were used with Tekin 2050 and 2650, 4s 4500 30c Turnigy.

Is there any possibility that the 150a is limiting current by its setup?
Tho I would agree I don't see the 1/8 4s cars pulling the amperage that 4wd sc do.
In a 10min main i use 3600mah with my iX8/1900 T8 and with simple math its only using 96w per sec ... Avg that's only .06amps

My 4wd sc last season (Rx8/4600) used 5700in 8min ( which was 97w per sec at 1/2 the voltage so is twice the amperage)
I would guess u would notice the difference with less voltage .

I currently run the rx8 and have had no complaints so far, but also very little time actually racing it. The hotwire interface is nice but something handheld would be ideal. I hear it is in the works which is a plus!

Ive yet to run the Castle MMM but have had mixed emotions about other castle products and their service.

LRP, no thanks. Owned multiple LRP products over the years and everyone has failed me multiple times.

If something does happen to my RX8, ill most likely pick up a speed passion SA V2. My only gripe with the Speed Passion is that it is large, very heavy, tough to fit in certain buggies, and HORRIBLY ugly. Otherwise they are bulletproof and for 75$ shipped, its hard to beat.

Had good luck with Castle service here, the main issue was the repair times were longer that I would have liked, but they honored everything, and have a 1 year warranty that beats pretty much everyone except maybe Viper.

I just wish they would finally offer a 1/8 ESC with sensored setup with all the bells and wistles.

I can't believe that they haven't come out with a Mamba Monster Pro yet.

I'm running a MMP in my MBX6 eco and have had no problems as of yet. IMO, the MMP is the best esc out there for running a 4s setup.

Sorry for the interruption, but your math (or physics) is off somewhere. Your conclusion is right, however
To get the average amps you have to divide the used mAh value with the runtime measured in hours. 10min is 10/60hours, so the result is 3.6Ah / (1/6)h = 21.6A.
Watts per sec is also surely not what you meant above.
Similarly the SC average comes to 5.7*60/8 = 42.75A.

U r correct don't know what I was thinking . I forgot about the hole amp hour concept. But i was trying to breakbit down to amps per sec for some stupid reason .
But to further my idea with ur correct #s if u run on power 50% of the 10min that will double ur current demand (43.5a ) and i wouldnt think a 4s capable esc would be stressed by this or would it be noticible from 1 mack daddy esc to a 80a esc .
Now depending on c ratings of batterys and gearing i could see the lesser amp esc being worked harder.
