| Best esc for outrunners using 4s?
Like the title says, im looking to run a outrunner on 4s. I don’t necessarily need drag brake but i need forward and reverse. One thing is though, it cannot have an aluminum case. Sent from my iPhone using Tapatalk |

These guys seem to have it mostly figured out: Silent outrunner and ESC for less then $60 Sounds like basically the same thing as what Holmes is doing with their Crawlmaster Mini ESC https://holmeshobbies.com/electronic...-esc-1242.html ... just much cheaper and more user friendly. I'm still waiting for someone to just build/program them to be rtr (from the sounds of it, the HH version wasn't quite ready for prime time, at least not on 4s) so I can hit the easy button. |

| Re: Best esc for outrunners using 4s? I've got a programmer on the way from HH to hopefully get this combo updated and running on 4s... I'll keep you posted.

The wrath32 and crawlmaster are different. Im loonking for something thats actually going to last on 4s. It will be in a super light rig, but the binds and lines i get into will prove that an esc cant last. Burned up a few br minis in my time on 4s with some 40t skewed 3 slots..

| Re: Best esc for outrunners using 4s?
Despite my poor wording, I wasn't suggesting they were exactly the same, just that they have very similar function. I recall people using several models of cheap esc's (along the lines of the wraith32) of different amp ratings and still programming them in the same manner. All of that is out of my wheelhouse, but it seems that an electronically minded individual could gather enough info from the thread I linked to get on the right path to acheiving CM9000's goals (which sounds like more than a few of us have the same goal.)

ive been using the chinese 120 amp waterproof escs for my outrunners the bec wont hang with 4s but with a external bec they work fine on 4s but the start up leaves alittle to be desired when run side by side with a castle mmx my only complaint is the slight coging at start up and extreme low gearing dosent.seem to help vary much although its still not bad enuff to make me want to swap the castle back in probably not the best esc for pure crawling but work good in go fast rigs like a yeti i also have one going on 5 years now in my redcat blackout https://www.ebay.com/itm/120A-Brushl...-127632-2357-0 Last edited by ferp420; 02-15-2022 at 06:26 AM. |

heres the same esc they offer them in 45-120 amp versions and the 120a version says 4s https://www.ebay.com/itm/Waterproof-...-127632-2357-0 i think the specs in the first link were for a lower amp rated esc cause thats the first time ive seen them rated for 3s maybe they lowered the rating cause the bec cant handle 4s i dont know just guessin Last edited by ferp420; 02-15-2022 at 09:18 AM. | |

Flier esc's on ebay. Seller is rmamba. Up to 500A, otherwise xclass quad copter esc's, if they run blheli they can be programed for reverse. Many still need external bec. Sent from my SM-N986U using Tapatalk |

| Re: Best esc for outrunners using 4s? I have been running my crawlmaster mini on 4s with 2040kv motor for quite some time now since upgrade the firmware to v1.2. No problem at all. I've been using arduino nano to connect to my ESC to change the settings or upgrade the firmware.

I've also been running a Crawlmaster Mini V1 on 4S and a 2500kv revolver with no issues. It was too fast even with a 66T spur and 9T pinion so I dropped in a 1000kv Revolver. I'm not sure they're gonna be selling these going forward, John has been talking about the V2 already and hinted at the V1's being better suited to a normal 'in runner' motor as they put less of a load on them. I'd recommend running a BEC or direct power servo though. The tiny BEC they provided is only able to power the receiver. Back to the original question, I think the SW4 probably handles a outrunner the best out of the ESCs I've tried (Crawlmaster Mini, Mamba X, SW4) but its 3S max. I think it has a better overall smoothness at all rpms. Its also annoyingly loud if that matters to you. The Mamba X isn't too much different though so that might be a good choice. The Crawlmaster Mini is nice because its quiet but Its a sacrifice for sure. At low RPM and low load it can cog and stutter (or as someone explained to me 'step'). the overall throttle curve feel is odd, theres a crossover point at low RPMs where it kicks into a different more normal throttle curve/control but as it crosses over it can be a little rough. Anyway I love the lack of noise but its not the best in terms of pure performance. Last edited by HumboldtEF; 02-15-2022 at 11:02 PM. |

I have the 1800 V3 snub on my C3 ( just over 7 1/4lbs) with a MambaX on 4s and really like it. I tried a Copperhead in hopes it would work out. I have had 2 Copperheads (one was a warranty replacement) and they just stall. No good for me. I am now looking at that HH ESC you mentioned. I will need a BEC for and was trying to avoid the extra wiring. It is out of stock right now. | |
