which motor better for 6S??

[gearhd48]

Hey guys gotta quick question for running 6S. I have a AQ 2030 6pole and a Dynamite 4pole 2000kv, I have heard some not so good things about the 2030. Also which pole works better for the higher RPM? You guys are great and I, like many . appreciate you sharing your knowledge! And I thought RC cars were addicting! LOL

6S is a lot for a 2000 KV motor in general. You could easy smoke the system or worse, like ruin your boat.
I would recommend against it.
Most people running 2000 KV motors on 6S are using good stuff, Like Neu or Lehner. They have a system with low drag, like a hydro. They have carefully walked into it to make sure the system is lightly loaded and aired out when running.

6s mania is still alive and well.... I've been racing boats for over 20 years one only tried 6s last year for the first time.

Why is 6s so appealing to people barely wet in this hobby?

[NativePaul]

Why not 6S? If you dont intend to race, or your classes allow it, you can reduce capacity and KV from a normal 4S setup in a 4s boat andkeep the same power while lowering the amp draw, giving the possiblility of extra efficiency or money and weight savings on the ESC.

As it is usually the ESC that limits power, and Hi amp and HV ESCs comand a price premium, 6S often has the highest Power to price ratio.

However if I wanted a spec motor for 6S, it would be the proboat 1500KV one, not either of the 2 mentionied though.

Hey Larry, Ray. An answer to both of you as to why. I had a Gruapner hydro 25 yrs ago and ran 12 nicads =2packs. The Swifter hydro I'm trying to finish(LOL) I got advised to run a good 1500-1600KV on 6S for a safe 45-50mph,again 2packs. My sons Rustler (truck) uses 2 11.1 packs to do over 100mph. And now I picked up a used Impulse that can run.. you guessed it, 2 packs=6s. I know 4s seems to be a better power to weight ratio, but my 3s batteries seem to cover my needs. I had these two motors sitting around and thought they might work, but at this point from your responses I should probably look at a lower KV motors. Thank you for your input guys!

Sometimes you gotta buy batteries to suit your application. I have 2s, 3s and 4s packs that cover pretty much anything. I also have a couple 1s packs I made up for oddball stuff. You really don't need 6s in a 26" shockwave. Mine does 50mph on 3s and 65 on 4s. 6s is just extra weight and less stability as you've already experienced.

Ray, some boats just require 6s to push properly, especially if you want to keep things happy. Yes you can build a race boat on 4s (under a certain size mind you) and get you you want out of it for race conditions. Some of us wacko speed junkies (myself included of course) just try to push the envelope of things but try to do it somewhat safely and easily. I bet you'll agree that making a 35" mono go 60 on 6s is a bit easier than making the same boat do it reliably on 4s. That's a lot of reason a lot of us sport boaters go with higher voltage....and there's no rules making us run lower voltage. And another reason is like in the op's situation, he already has the batts and may not want to buy more (which I dunno why lol)

Hey travis ,Right now it's for a 31 impulse I picked up cheap that needs some work. Not sure if I'll keep since a friend is almost begging me to sell it to him, we'll see. I put my green SW back to normal/ well almost. LOL. My red one I decided to gut out to see if it's possible to lower the c.o.g and see if handling will be improved at any speed. And yes I'm on the verge of picking up a 4S battery, the weight to speed ratio just seems a no brainer. Things take time when you only get one check a month, but sucks when you have all that time to dream & scheme.LOL

[kfxguy]

If you wanted to run that on 6s, day in and day out and have it reliable, I would put a seaking 180 in it and a 1500kv tp 4040 (yes they make a smaller version) for overkill and be able to push a decent prop or a 3040 1600kv. I'd sway towards the larger motor myself.

Sure you can push a 35inch boat easier with 6s.. 2p mainly because people running 3s packs from other hobbies wanting to run their batts in series pose a major risk or lvc let down if their cells aren't up to true C ratings required for boats. If they are running truly high end batteries, fill your boots, if not at worst cases.

When it comes to racing in NAMBA we have a length limit for reasons. A longer boat on 4s is more stable than the 34inch limit. Fully harnessing all the power of 4s2p in a 34 inch boat takes a lot of time to tune and trim out compared to a larger, longer boat. Anyway, if you got the batts that can pull it off, go for it. Have fun, go fast

Yea ....that's about what I saw coming...was just hoping to save money and use one of the other two motors and a seaking 120. Thanks for the input. Well now this got me thinking...tweak this one-no electronic drive components, sell to buddy .. save up a bit more for new impulse31 where I can run 3 or 6s until I get the 4s. or get 2 4S batts for the year???? decisions, decisions Oh Ray, It's o.k you don't have to like 6S it's not for everyone. But I do have to say that I know sometimes 3S just don't cut it either. Thanks again guys!

Hey Gearhd48, I think the pursuit is only slightly larger than an impulse? I guess you be the judge. I run 2x SMC 7200 3S (and 2S) hard cases in a series with a 1480 kv leopard 4092 and M545 prop. I run exactly 4 minutes and my batteries are 3.82+ per cell with okay temps. If your not a super speed junky lol 5S1P works well with this setup (3S port/2S starboard) but surprising my temps seem about the same as 6S for whatever reason. I only run 5S so that I can take advantage more sets of batteries. At 4S I have no problem letting my kids take the wheel. I like the options.

Just keep in mind, if all battery specs/brand are equal and motors at the same loaded RPM a 6S system only needs roughly 6,667mah to equal a 10,000mah 4S setup. So in my boat even though I am running 7200mah 6S1P, on paper I am matching a 10,800mah total 4S2P. In use it may not translate over to the real world 100% but it is at least something to think about.

I think the way people get in trouble with 6S is just taking a kv motor that was ideal for 4S and slapping 6S in there. Then expecting no other changes needing to be made like reducing prop size and run time.

RE:

Thanks Jamey, Good points you made and well put! I did a test run (experiment)on my shockwave 26 to see if it was possible to stuff 6s in it and went through a lot of learning. Had small prop on it, the 2030kv ect. it was interesting but very unstable! KFXguy helped walk me through it. see the danger and did it anyway. LOL Had a gut feeling the old impulse would probably be about the same with that motor, in ways with that motor..too much! Just was hoping I wouldn't have to buy another motor. will be selling it shortly to buy a 14.8 or 2 for the shockwave and wait til next year for the new impulse so I can just plug up and go.g

[T.S.Davis]

I understand Ray's frustration. I know you've heard it in my postings before too.

If you're going to design a boat/setup for 6s then by all means go for it. Paul mentioned you could do so with less amps. Sure you can. But that's not what Ray's talking about. It's always someone wanting to throw 6s on a stock motor in a boat that should never have 6s in it to begin with. More often than not it's someone that has no business going that fast. Sometimes in a BJ29 with no added reinforcement at all that's going to explode on impact.

Travis and I have different mind sets. I've accepted that. He wants to go fast first and racing is of no concern. An Impulse on 6s can't finish and therefore does not compute for race heads. bzzzzzttt A boat that can't be raced makes sparks and smoke come out of some of our heads. Could be residual speedo smoke with me.
