Brushless ESC recommendation needed

Where do you get 440 from?
The Speed Passion Crawler Master L is a 23 turn Feigao FG-MBLS540L with a max amp load of 27. Speed Passion just added a sensor board to it.
Datasheet for it is available here

Either one would probably do fine.
It varies. The best thing that you can do is research the particular motors you want to use and see how they run. There is no universal number that goes across the board.

See below.

"In general", the lower the turns the higher the amps. More power (lower turns) typically the higher the amps.
Granted, there is a difference between manufacturers and machine wound vs. hand wound.8)
Yup. "In general" is a very good disclaimer. I would add "but not always" to it. :ror:

I'm goin with the Traxxas 3s velenion system for my scx10. The Traxxas speed controller is already waterproof, and has different settings. The people who pointed me twards that said that sensored motors only eliminate coging, which the low gearing should do anyways.
Oh! And Dollarhobbyz.com under traxxas slash 4x4 vxl isa good place to get it cheap....er. 8)

The VXL motor is one of the coggiest ones you could possibly lay your hands on, I don't care how you gear it. They are fast and powerful and waterproof, but absolutely do not like to go slow.
i run an electronics box on this particular rig so water proof is not a requirement. I have herd some good things about this crawler master from a guy running one on his creeper, going to send him the link on this 120a unit just to get other opinion.
I have the BrushlessHobbies and the Crawlermaster motor. As the guys said, you'll never tax the 120a ESC with that motor but I'm going to use it in my Wraith. When we go to the beach I'm stuffing my Castle 1410 (3800kv 4 pole) in the Wraith for some FOFF fun!
Anyway, the speed of delivery and the support from BH has been great. I still don't have mine all the way setup but from what I've seen I like it quite a bit. Also, my Crawler Master motor (same as yours) is brand new and I've never used it so I'm not sure how performance is. With some initial bench testing I'm worried the sensor board in that motor may be bad because it doesn't seem to run any different sensored or unsensored.
I really need to get a sensored motor that is known working and see how that runs.

are you seeing a lot of glitch? that's great to hear about this ESC, the more looking I do, the more I come back to this unit over and over again.
I posted a separate question (because it really is a separate issue) asking about adding resistance to the censor circuit by soldering it to my pass through connector on my electronics box. i am worried that will screw up the performance.
So far no glitching whatsoever and I'm testing it basically with two chassis side by side. I have the 120a esc installed in my 1/16 Traxxas right now and basically pull the esc lead out of another truck and plug it into that receiver. I should hopefully have the new receiver for that car this week and can actually drive it a bit.
I don't know if my SP motor even works properly though. I hooked it up and like I said, it seemed the same sensored and unsensored. I'm thinking it's partly due to the fact it was just on my bench and that's really not a good indication of how smooth a motor will be. I need to stick it in my Wraith, but I just finished wiring that up all nice and pretty and don't want to tear it all apart. I may just stuff the motor, esc and second receiver in so I don't have to pull it all out the water resistant box my other stuff is in
Anyway, you could probably get away with the 80a ESC, but the 120a is only $5 more and they are the same size so I opted for that. One thing, it's smaller than the current Castle Sidewinders and can actually be servo taped to the chassis where the larger ESC requires a bracket to fit properly. In the crawler this will be nice because it's smaller and you may even be able to get away with taking the fan off.
I'll have more in my review thread (here in the electronics section) as I get more into it.

I still don't know if the reverse is instant. I had mine setup wrong and it would go from forward to brake and then after a short pause go to reverse. I'm talking about less than a second, but noticeable. I think my issue is I had drag brake set to 0% in the program though. It think if drag brake is set it should show a shorter change over.
your talking Greek to me at the moment, i will have to get in a learn the programming. but i ordered it, enough people have said that this is either a good unit for where impressed by the specs. This is including the guy wanting to sell me the used the mamba, he told me i should buy this instead LOL. so I got BH 120A unit, a set of 6000Mah 2s2p Lipos from hobby king (US warehouse had them for once) and a another Eco 6 charger seeing as i just gave mine to my dad LOL. thanks again for the advice guys, i think the bronco just got a whole lot cooler.
