Ya, that was quite a while ago. Time really flies.
I ended up buying another crt.5 and then sold it so I could get a RC10 T4 :whistle:

I really think they need a 12 step program for RC

You have a good point about crawlers. It's a must to have a good motor though. I'm sure a HV or purple feigao motor will have cogging issues.

If you are looking to use a sensored 4S motor than the SP is a good choice.

Both ESC Prices are comparable
Both ESC PC programming and updates are comparable

MMM Pro's over SP
- MMM Can handle up to 6S Lipo VS SP 4S Lipo max
- MMM has a slightly smaller footprint
- MMM has a 5AMP BEC vs SP 3AMP BEC (this won't be an issue unless you plan to run some major current drawing servo's)

SP Pro's over MMM
- SP runs both sensored & sensorless motors (Sensored in dual mode)
- SP comes with a hand held programmer that you can use anywhere without the need of hauling around a laptop
- SP On/Off switch is FAR superior to the MMM switch. The MMM power switch is notorious for switching off when the vehicle takes a hard hit. This has happened to me numerous times and I finally shoegoo'd my MMM switch to the On position. This obviously isn't a hard selling point but a small notch in the belt for the SP.

Oh BTW,
I will be getting a RX8/2050 combo as soon as I can

So I'll be able to make a comparison between all 3 ESC's soon

The 2pole feigaos will lack low end torque. I am using 8+ pole outrunners, between 800-1100kv on 3s lipo and they work very well with the castle escs. I also run a 13.5 novak motor on 2s in a "rock racer" and it has enough control and torque to make it crawler capable. I have a sp 17.5 that I would like to try, but I think the speed may be a bit low. Also have a new hacker 13.5 e40 motor, pretty!

Now I would like to see a decent sensored esc with 3s+ capability in a small footprint capable of 60-80amps cont. And some purpose built sealed can outrunners with high qual materials and a sensor too. Run them sensored only and they would be the ultimate in slow speed control and low speed torque.

Just trying to let you know the best bang for you buck, but to me it seemed like you're a SP fan. How are you liking you LCD handheld programmer? You know who gave Hobbywing the idea? You're chatting with him right now. Just to get something straight, I don't work for Castle and yes I have a Hobbywing Xerun 120A (SP GT Pro) and was the first one to test one out for Hobbywing to make sure everything was working fine. I was the first to hook it up to a Novak HV motor and run it with 4S lipos a few times in my TC3T. So best bang for your buck is the Hobbywing 80A 4S which Mike sells for less then half the price of the SP version or you can get the 150A 6S which is still cheaper. I just didn't like how you first posted here and it seemed like a personal attack on the ones who posted before.

I knew about the HW ezrun esc's before I purchased the SP. I purchased the SP because I prefer dealing with a US distributor. We can agree to disagree about the best bang for your buck here.
For me, the juries out until I get my hands on the RX8.

P.S.
Yes I like the LCD programmer very much. Thanks for asking...
People have been asking for hand held programmers a long time. It's nice to see a company finally listen to what the public wants.
It's too bad you don't work for Castle because they could use some of your insight

Now that Mike sells the HW 8th scale units, I'm sure he can do the same if the ESC(s) fails.

Now the RX8 is a nice system. I've done a modification to one of my 4 pole Sensored Aveox motor and it worked out very well when I used it with my 10th scale ESC. Good thing a company saw the benefits of a sensored 4 pole system other then Aveox which no longer involves in RC.

Hey, do you want to start a forum fight with me? :whip:

:lol: :lol: just kidding

those were the days, eh? Less smart guys around back then...

Thanks for your response. I am intending to use the esc in a monster truck.
Which esc can handle heat better? Same setup (speed, vehicle, motor, cell count... etc)different esc. Which esc will run cooler?

Wow, I think this thread got much better over night.

Glad the hostilities subsided and everyone is happy again!

I remember you too starscream, I actually was on this site when it first started under a different screen name. After the collapse I never could get the old account back.

sorry to get off topic but

your answer is the tekin RS run an external bec and cap and they are great on 3s and 4s.....ive been running mine in my T4 and slash on multiple different motors (8.5 sensored-2s, 10.5 sensored 2and 3s, and feagio 9l - 2 and 3s) it is an amazing litte (actually tiny) ESC, ive enjoyed it so much in the past month i bought another last weekend :yes: the tekin redline sensored motors are also great (had 8.5 on 2s geared for 40mph in a t4 and ran two 5000 packs back to back (40 solid mintues on the track) and the esc had 4 lights out of 7 and the motor was 141 :gasp:

So, if the SP ESC is basically the guts of the 80amp unit that RCM sells, where can you get the outer case? What exactly is different between the two?

You could get it from Schumacher, but if you look at the Speed Passion site, it's just an aluminum piece that was added on. It looks cool, but you don't need it since it will add more weight to what seems to be a bigger ESC then the Mamba Monster.

Hmm, I wonder if it has a good drag brake? I am guessing the hotwire interface would be required to set that? I am not all that up to date on the tekin stuff, maybe I need to do some reading!

The Tekin RS ESC's are very nice. They seem over engineered so they can handle more than what they are rated for. You should be able to change the drag brake settings without the hotwire.
