ESC for Neu 1530 8s SAW

[Kaotic]

I'm looking at running a Neu 1530 .75d (1580kv) on 8s. I was thinking about the SF pro+ 300. Is that enough ESC? I was also looking at MGMs but I'd rather not have to order over seas.

Im going to be running a 1521 1577kv on 8S ...thats the esc I'm using...those mgm's are nice but a bit costly...

Depends on the boat, prop etc...you know that lol. But I would think in the "affordable" realm of things the 240 or 300 would do. I've run neither myself, I have a 240 for....well...was going to be for my cheetah on a 1527 1250kv but I may just run a seaking 180 in it and put the the 240 in my shocker (saw mostly) on a (planned) 1530....

I'm convinced the seaking 180 is a bad beoutch. The 240 "should" be a step above that. Maybe some other guys who've run them will chime in...but I've read nothing but good about them.

They are pricey that's for sure. I'm just not crazy with the weight of that SF300 oh well.

I love the SK180. I just bought another one for my new rescue boat that will be running a 4074 with. I wished they would come out with a SK250 or something in that range.

[olwarbirds]

Jay, I wouldnt worry bout the weight that much. You might find out your glad you have it with the power your going to be putting out. Yeah I wish hobbywing would make a hv esc good as their T180 and T120. Ive been using Hobbywing esc's in hi performance ducted fan jets and race planes for about 6-7 years now with good luck. They have been approached by the boat and plane guys to build one... maybe someday.... what hull are you setting up Jay ? ... DJ

[Kaotic]

It's going to go into a 35" DF mono as soon as they come back into stock here. I hate waiting for motors

You can buy the 280amp MGM 28026-3 X2 series Lite for $286.86 from Rocket City Racing http://www.rocketcityracing.com/cart...ategory_id=183 it's only $16.00 more than the Swordfish 240 Pro Plus @ $269.95. The MGM Lite series is MGM bare bones line of ESCs same basic ESC as their X2 pro without all the bells and whistles and even at that it has more features than SF. If you do a little research you can get MGM quality for almost SF money

[olwarbirds]

Chris, thats a nice controller, but its only good to 6S brother...wish it was a 8S I would be all over it...DJ

[Kaotic]

I actually have looked at those MGM Lites several times. But I'm leaning towards the SF 300.

[Kaotic]

MGM 25035-3 is pretty close and goes up to 8s

[flraptor07]

Oops DJ I forgot about that being 6s, I got one for my GP400 build. you could step up to the 25035-3 Lite series for just a little more $ @ $324.50 it's 8s http://www.rocketcityracing.com/cart...ategory_id=183

[olwarbirds]

Jay, I was looking at it. cost a good bit more when you do all the addons. It is no doubts a quality component. Its a 250a continuous 300a peak 2-8S...SF 300a continuous 380a peak 4-15S...MGM w/p is an add on cost, SF is already w/p...mgm Id want would be 500$ + ... I need 3 esc's soon... I'm gonna try the SF first

oh I missed that one...

[Grazacind]

I run the MGM esc's for my saw riggers and will not run SF esc's anymore. MGM run and hide from SF. Remember when you run SAW you are pushing the limits. SF gear is rated at its peak not really its constant. The SF300 in a rigger is hard due to the size and weight. Just my opinion anyways.

Comparing the Swordfish 300 to the MGM 25035 is like comparing a decent full size car to a really nice golf cart.

The SF300 is capable of double the work that the 25035 is capable of. Your instinct is right in my opinion. Go with the 300.

Just an FYI: If you do ever order a MGM, the WP/WR designations are confusing. It's the opposite of what you would think. "WP" is only water resistant. "WR" is the model that will be potted in rubber. I actually prefer the "WP" version as they can still be repaired.

Thanks Keith I think that's what I'm going to do.

[olwarbirds]

Tks Keith, yeah I seen the $ diff and figured as much...No space problem in my drag boat hull....the Fantasm being a twin, I will have to watch space usage....

[RaceMechaniX]

To be brutally honest, there will not be many ESC's that are going to handle that motor on 8S. You are looking at somewhere north of 400A on the accel stage with a very low inductance motor. I would not recommend any of the MGM controllers, probably not even a 40063. The MGM's have too many safeties to prevent over current operation and you will just find the controller pulling power out. The Swordfish 300 or possibly a Fightercat 400A twin board ESC if you can find one. Definitely use short wires, heavy connectors and the strongest batteries you can afford.

Sf just does not impress me at all..I will not buy another one

Ok, so what ESCs are you using? What amperage?

Keith the only thing I was comparing was price, they were saying the MGM was so expensive. But if you go with the X2 Lite Series they are real close to SFs prices, same basic ESC as the X2 Pro just without all the bells and whistles. It still has all the data logging capability of the SF Pro Plus and it's about half the size of the 240.

I don't know much about those ESC's but I think that one only goes up to 6s.

Tks Tyler, I'm glad you spoke up. I have no doubt on what your saying. I had read in the specs about exactly what your saying and was concerned. I'm going with the SF300 and I'm building some serious cap banks to help some too...sure wish a manufacturer (HW) would step up and make us some good HV high amp esc's...

[iridebikes247]

sf300 is an awesome, very robust esc. I don't think you'll be disappointed

[Kaotic]

Now if I where to go down to a SF240 HV with a 1521 would that hold up? Or just be safe and go with the SF300?
