Are you saying A-Main is the evil empire? :lol:

I dont get it... CC has been making the HH ESCs for a long time.

I have a question though- is it "brushed only" just because it's missing a wire? Could I open it up and solder in the third wire and run a BL motor with it?

*crawls back under his rock...*



:sleep:

No it's custom designed for brushed iirc

Awe, bummer. That'd be a sweet deal if I could just modify it to run BL. :yes:

It's aimed at rock crawlers. :)

Personally Im going to use a MMPro for mine; that way I have option of brushed, or sensored/sensorless brushless, or can use it on something else. Probably take off the fan as the loads, etc. shouldn't be high.

Just be aware that the MMPro's BEC won't do anywhere near 5A continuous...

And this is an issue with? Not had an issue with it in my XXX-T or SC10, granted both using standard digitial JR91000S servos

Well, seeing as how the HH/Castle ESC has a 5A BEC, I just wanted to mention that the BEC in the MMPro is not comparable. Its output voltage drops significantly around 2.25A. In 1/10 scale vehicles, it works OK, but many have had problems with strong servos and/or in larger vehicles.

Ah, yes. Well, in my case, its going in an 1/10th rock crawler, so think things should be good. But definetly in an 8th scale vehicle you are probably right.

Would be interesting to hear from Rob on how the HH is different than say a Sidewinder SV2 which it looks a lot like, other than the 5A BEC and being only brushed.

or when you use bluebird/cheap servos....

I would say the cheaper servos don't help but I don't know if that's the whole problem. It's a 3amp bec which should power most any servo out there. I have noticed the spektrum receivers are finickey with voltage fluxtuation but my mmpros have ran a few diferent digital servos just fine. They seem to really like the futaba brushless servos(me too!). The only issue I have had with mine was when I got my jammin sc with a ballistic 4.5 the rx would reset on a full throttle luanch. Never got it any other time or with rapid or locked steering inputs. A glitchbuster later and everything is good.

This speedo makes me want to break out the lathe and get some mods around 10-12 turns and relive the glory days. Oh yeah I can do that with the mmpros hmmmm....

Not sure what servo your going to run in your crawler but most of todays 'comp worthy' servos, draw well over what most internal becs can handle (the HH being the only except but it's still only 6v). If your running 7995, 7950, S9157, 7980/7990, 7954SH, 8711 your going to want a CC bec minimum for power wise. Remember crawlers work servo's A LOT harder than other applications. Plus most of those need around 7.5v to get the most out of them:yes: Also I am pretty sure the HH is a completely different board to the sidewinder original and SV2, the only similarity is the sidewinder case. Which is shared with a number of ESCs now.

While I admit to being a bit of a newbie in crawler world, I think all those are complete overkill for a 10th scale crawler. Personally I was just going to use some non-high voltage servos I had for 8th scale nitro applications; should have more than plenty torque but where it can operate on internal BECs.

I doubt its its own board unless its the same board as the new Axial ESC that is a rebadged CC; otherwise the run size would just be too small for its own board.

In comp crawlers it's around a minimum 30kg (400oz) of torque, anything else is just a waste of money. Might seem like overkill but after you go up in torque you can never go back. I know for a fact that JRH has commented and said the only relation to the sidewinder is the case. I don't fancy going through the entire RCC forums to find where he posted that, but I remember it clearly. Neither the sidewinder or the new axial can handle 6s nor come close to the rock crawler specific programing or physical features of the HH they are different ESC's. The only pictures I can find right now of the board on the HH itself are a very very original proto that only recently gave up the ghost. Not much good for ID in comparison the a sidewinder.

Edit, I've had a bit more of a look I can't find any pictures of the brxl board for comparison sorry. Also sorry if I come across as a bit of a know it all. And finally don't underestimate the popularity of the BRXL, it's a very common ESC in crawling circles.

Agree 100% with Kieren...

My comp Mini uses a 7955 on 6v, 22 uses a 7950 on 7.5v and the Super 7980 on 7.5v...

For crawler I actually use a BEC per servo i.e. the Super actually uses 2 CC BECs...

Geesh, I only have a 7950 on my 5T conversion.... well we'll go with what I have now, and will swap later as needed. :)

nothing will piss you off more than a weak servo in your crawler. I have stalled 9100hvt, 7950, and a 7980. buy the strongest servo you can find for a crawler, its not just nice to have its pretty much required.

and to sum up the br-xl its basically a super smooth super strong brushed speedo that can handle up to 6s and has a CC bec built in, not much in comparison in power or price wise, it also has crawler specific software.

Well, to be honest, 6s Lipo in a Crawler :surprised: 80 Amp continuous :surprised:...maybe I'm missing something....

I've two Crawler, a 2.2 and a Big Scale (look at my signature) and never go beyond 3s lipo. My motors are brushed, 540 size for the 2.2 and 600/650 for the big one. Maybe in a stall situation they reach 30 ampere, but normally they don't use more than 10 ampere.

On the other side, the ESC has a quite standard BEC rated a 5a, that is not enough to drive the servos usually mounted on a Crawler, so You need an external BEC anyway.

Yes, the price is actractive, but for the same bucks You can get a Castle Sidewinder, that can also drive brushless motors and is perfectly rated for a crawler.

Bye, Andrea.

Holmes esc has active drag to. If you have tried it yet it's amazing.

I run 4s on Super.

I actually just swapped from br-xls to dual micro pros on the 22, run a STD micro on the 1.9 and br-xls on the super.

Castle all the way; Now I just need a sponsor! ;)

Did you resolder the with a higher guage wire on the micros? I do have a MicroPro running around I could use.

No its normally the other way around - skinny down the wires to 16ga or less to save weight...

PS Word of caution - Using Micro Pros is considered edgy on 3s with a 35T motor... Just be careful about what your setup is.

No way I would use one on an LCC or a single Micro Pro on an MOA or even an AX10...

I'd really only use Dual Micro Pros with an MOA rig or a 1.9 crawler.

Ok, well, guess I'll just look at the MMP then and potentially a CC BEC as required. I really hate to be limited to brushed only.

Almost the same, except I don't have a mini, and I'm thinking of going 7980 in my new 2.2. But I think 46kg in a what will be 4-4.5pound rig is a bit much:lol:


The MMP will be a good alternative, it's quite popular with the losi guys who have to run 17.5-21.5 sensored brushless on 3-4s just to get enough power through the worms and out to the wheels. If your only going to use it in a crawler, the 1s version might be a good alternative. No fan or internal bec and the nice solder posts, make it perfect for crawlers. As you should never really see the fan come on in a crawler and the internal bec is only adding weight. The only disadvantage is if you chose to get a HV servo and run the bec direct to the servo, as some receivers don't like more than about 7v plus the amp draw isn't to good for them either really, you can't use the internal bec in the ESC to run the receiver. Because there is none. Oh and if it's going in a crawler, a bec is required, no question asked. Internal becs in ESCs don't like servos being turned without any forward motion of the car.

7980 is a bit heavy / big for a 2.2 but my opinion may change.

Stupid thing with the 7980 was the fact that they scaled up the mounting holes spacing - how dump are the cad designers!

You could be right, but what other servo puts out that much power:mdr:

Well I made the mounts on my super for the servo so that part hasn't worried me, but it could be a pain on other cars. I do wish it was a bit quicker though. If they regeared the 7980 so it had about the same torque as a 7950 but much faster, I'd pick one up at the drop of a hat. Something around 490-500 ounce torque and 0.1 second speed would be perfect!

Kieren

On which motor ? A brushed one ?

4s on homles 35t brushed

Just figured I would comment here.

The only parts that are shared with the sidewinder and the TM controller is the plastic case. The board was custom made for me and the design is new (as of two years ago when we designed it).

6s 80a overkill for most crawlers? Yes it is, but overkill is not always a bad thing. 5a BEC enough for most crawlers? Yes it is, unless you are competing and are using over a 300 ounce inch servo or need to turn up the BEC voltage.

We will be adding some new features to the firmware as time goes on as well, ones that will really add features that crawlers and offroad bashers need. This controller is specifically designed for total motor control, and recently we have been installing quite a few units into battle bots as well since the features really work well for them.

Beyond that, a new controller that is smaller is being developed as well. But all the software features will port over.

Since we are discussing servos, I would like to add that the 1/4 scale servos are also very good options if you are scratch building mounts. Even if the ratings are a bit lower these beasts just move the wheels. I have compared 2 hitecs, one std size high torque (forget the p/n) and a similar spec 1/4 scale. No comparision, the 1/4 scale servo moved the wheels when the high torque std would not, and it held center better as well. Just another option, and mainly for large vehicles, as these servos will not fit most places.

Well if you are targeting 'bashers' too, then brushless (sensored/sensorless) support is required. No one bashes with brushed, unless you specifically mean 'crawler bashing'.

But anyways, what about the MMP and the TM? Any correlation between the two other than both coming out of CC...

No correlation between the MMP and the TM, although I wonder if my prodding about having an adjustable BEC on my unit influenced the design of the MMP. Care to comment Patrick? :lol:

If I remember right it was a trade off between power and adjustability. I wanted power.

Now this I want info on:mdr:

Kieren

I will wait for comment until some protos are done. I can't let the wrong cat out of the bag :lol:


So, I just gotta ask. Why is this the dark side?

because it's brushed vs brushless...

I'll be waiting:mdr: How far are protos out?
