If esc were so cheap and easy to build.. why would you buy them ?
Please show me where 70usd will supply components for a 63v300A esc .. :)
Dont be shy !

The only person I've seen make his own speed controls was a guy from Germany.

He built up a riverrcat hull and hand made everything except the hull and motors basically.

He is both a mechanical and an electronic engineer. It was easier for him since he had access to PCB production or perhaps he works at an electronic manufacturer I'm not sure.

It can be done. I'm sure he copied some designs from other esc manufacturers but it was impressive. This was a good 5 or more years ago.

I think you are missing the point, and yes I am confident the 300a esc doesn't cost more than I stated $70 american ones! I work in r&d and manufacturing and build boards overseas so yea. Again I don't want to make anybody mad by saying it's a cheap thing to build, just because when I see it I know.

Sf300 run staged mosfets for the full 14s power rating.
Find me any , where the required minimum of 18 are available for under 70usd :)
Assuming you'll supply the boards and other components free of charge .

Thanks for the response and standing behind your product.

I know Oscar has had a 300 that was not covered by warranty. But Id like to ask the other people that have complained about the product in this post. How many of you have had a Hifei product that you have returned and then not covered under warranty?

I can say over the years there have been very few that have been returned not repaired. Most have been esc's that come back in several pieces.

Too bad we couldn't get Andy Kunz to design us something. Makes me miss the brushed days.

Last i spoke with him, he was working at/for/with Spektrum as a programmer.

Over several years I had a 100% failure rate with Castle Creations(cremations) 240HV ... and to some extent the 240LV
*user error .. water damage ( but the bloody thing was always bone dry ?? )
*user error .. died on connect .. please explain how ? ....
*user error .. too many amps .. ?.. huh ??.. 1515/2200 4s1p25c4400 on 240LV .. wth ?
*user error.. overheated .. bah-humbug..new esc fried on contact ..
*user error .. cap legs burned off ... excessive load .. ditto 1515/2200 4s1p25c4400 on 240LV
*user error .. unable to program esc.. how in heck can Catle-Fink usb programmer put too much voltage in ???.
*possible user interference !! .. . .. I blame the Mexican assembly workshop.......
Each return from Au to US was a costly exercise indeed .(+50usd postage ). costly repairs for what were not user errors .. excuses and near zero customer service.
Frustrated at repeating out-of-bag failures , flabbergasted at inane 'user error' reports, horrified I was charged repairs and postage for flawed product assembly..
When sending esc back to Castle for repairs, this was a 6-10 week turn around from here .. adding 40-60usd to the repair bill.. user error ( but it died on first contact ? ) ..we can generously offer you 1/2 RRP new replacement ( and if this dies ? ) ..Please be assured the esc will work fine ( 2 surface mount component were rattling around in the retail bag, FFS .. it FLAMED on contact .. USER ERROR, no warranty. oh come on FFS .. .) ...
Beef Hooked.. Castle lost my faith
Castle finally abandoned marine esc ... .. problem solved.

Anything posted US→China→US is a 5+ week journey .. unless 'express' which halves the time but quadruples the cost.

As an electronics engineer designing ( and repairer of) complex circuits .. having a variety of people jump on the bad luck band wagon and sing songs of failures doesnt truly help with product correction... indubitably there is always room for improvement even with the best available this rings true ..

We've lost Castle as a provider ...
We've lost Shulze 40-160 .. ( why stop manufacture of this brilliant esc ?? ... why release the 40-161 which is insipid by comparison ??.
We've no faith in FlierRc pop-n-blo esc.
We love MGM, but massive amp provision = massive esc .. and if you're happy with MGM, why post in this thread ?. ..how many of you have actually held their 63v400A ?.. haha

here for the long haul, not splashing about in the shallows.

I have the TMM 40063-3 for Race Boats X2-SERIES PRO. Ran it all last year love it.

I still have a 40.160 will run it in my 1/8 some day when I have some competition.

Possably the SW 300 is better suited for HV and not LV.

One of the controllers I sent back is a SW 220 that I tried to run a UL-1 motor on 4S and it quit. the other two SW 300 and one SW LV 240. They ran for a while, one died over the winter while sitting. We will see after they get to china.

Shouldn't have to pay $1000 for a decent controller. For that price I'd expect it to do more than just be an esc :-).

It was $825 shipped and the Schultz was $675. I love racing scraped together all the gold I could find and bought one and a friend bought one at the same time. I had my Schultz for 17 years, plan to have the MGM for the same.

Seeing what I have in my dead esc drawer, I probably should've done the same and used that space for something else.

Seeing that I'm not the only one that's had issues, I actually ran all year with a Swordfish 300 lite in one of my boats. I replaced the tiny jumper hose, bored out the cooling line on that side as it's a smaller inside diameter than the inlet side, added more conformal coating to the whole board and added extra caps. I don't think it would take much to improve these controllers and make them a very good product.

Oscar, how do you set your voltage cutout for lipo protection? I have had some issues with my 300sf where it seems like it is going into protection mode but it never will return power. I get it on the bank, flip the power off, back on and everything is fine. Weird stuff, I hope it is just the lipo protection kicking in but it just doesn't act like I would have expected since it never starts working until a power cycle.

Hey James, it's set to 3.2 I believe. I can text you when I get home with the exact setting. Check the data recording to see what it looks like.
