Obsession with 6s

[Darin Jordan]

What parameters? I'm not trying to bust your butt, but this is going to happen. People will see 6s esc and assume we drop in 6s. Will ProBoat give some instructions what to do?


For you it will work, you know the ins and outs of what to do, what to look for. But for Joe Newbi it just not the same.

Feel free to bust my butt all you like. I jumped in! I wouldn't defend this decision if I didn't believe in it.

First, the Pro Boat guys, who are NOT boating guys, but generally are car bashers, ran the heck out of the IM31 and BJ29 with the 80A ESC and BOTH the 1800 and 1500KV motors, using stock props, and had "no issues at all"... Temps were fine, and everything held up fine. Traxxas has an issue because they did NOT have the right motor (2-Pole, originally), and they have "car rated" ESCs... (not going into the whole "plastic" thing... since the IM26/Shockwave 26, and some of the future offerings from PB, are plastic as well... I don't really have an issue with that)...

Novak, for example, rates their car ESCs at "300A", or whatever... The Mamba Max Pro is rated at up to 6S as well, with those TINY little 36mm 2-pole motors... and those ESCs are TINY compared to the new PB ESC.

The motor isn't going to care how much voltage is pushed through it, for the most part, as long as the AMPs remain reasonable. While the amps may be pushed up some, you aren't increasing the loading on the motor by that much. You may be actually pushing it up into a more reasonable efficiency level, though I'd have to consult with someone like Joerg to calculate this kind of thing accurately.

The "parameters" I mentioned are simple... watch your temps and runtimes, and don't over-prop.

Given the history of the PB power systems to date, and the number of people already "over-volting" the systems, I expect for the new system, which was developed and tested to work successfully on up to 6S, to perform as promised.

I will have a chance to beat the crap out of one of these myself... I'll let you know how it goes.

[Darin Jordan]

Speaking from direct experience... On 4S, you can make a Mystic go 48mph or so, with a 1.9" x 3.0" Pro Boat prop... however, things get hot and you burn stuff up after a short runtime...

On 6S, you can use the stock prop (1.6" x 2.5") and get those same speeds, and the system doesn't overload... You just aren't pulling the heavy loads, relying on RPMs instead...

[Diesel6401]

Ummmm... excuse me, but the Pro Boat 6S ESC IS a 6S ESC... it's bigger, and has been tested to be such... Not sure why this is a problem.

Darin I'm referring to placing 6s and 50mph on the website. This is what caused the mass explosion in new guys wanted to run 6s on anything and everything. If your not sure on my stance, I'm a PB/HH fanboy. I just don't agree w/ the marketing.

I do plan on purchasing a BJ29 at some point (money tree is bare), and I will go against my gut feeling and run 6s on it, just curious on how she will work. Here's the problem, guys are going to buy a new prop for the boat let's say a x642 as it was popular for the mystic&mg and run it 6s then get pissed and bash PB when it fails. New guys don't care or understand amp draw like us, they see 6s makes me go fast on the stock prop, if I put a bigger prop on ill go faster. That's their thought process. Just a little shocked PB/HH followed suit w/ this. I've always been a fan a u and grim and my words aren't to bash! I just see where the market is shifting and its concering. Just my 2 pennies.

Hey guys, thought you might like to see what a Traxxas does when it takes a dump under 6S power.
It was doing well, UNTIL he ran over a wake of another boat.

Sorry for your lose. Plastic mixed w/ high power rarely ends well. Noting againt plastic as it works fine in mild setup, key word is mild.

It belonged to one of the club members and he learned real quick that plastic is kayrap.
He learned the hard way and said he will never buy another plastic (fill in the words.)

Did the boat work on 6s, yes it did work. (short life tho due to the dumping) Would I recommend the boat for a new person starting
up in FE boating (knowing it says it can run on 6S)?, uh, nope,,,,,,,,,,,

The temptation for boosting the power to 6S is just too great for the new person just getting into FE boating and
not knowing the in's and out's of what to do.

This is just my opinion folks.

While I understand the idea, I don't agree with a lot of what is being said in this thread.

High RPMs is not the killer everyone makes them out to be. The old 25k-30k RPM range is NOT a rule. Propped accordingly, a 40k RPM boat can be perfectly reliable. I know this, because I've done it. 40k may not be the optimum range for every application, be neither is 25k.

There is way too much speculation in this hobby from people who have never experienced a given result, but swear it's inevitable.

In the past years the rate in which new technology has developed has increased drasticly, and electrical components have become more and more affordable. If you're still doing what people were doing ten years ago, or even five, I'm sorry to tell you but you're experience is becoming irrelavent.

TO be honest, thats wrong with the spartan thats just blown up in the picture?
I can see ALL its hardware still in it! thats got to be a good selling point


Ive found higher RPM with smaller props = a lot better handling boat in general.
Less snaking when under power, however the lead bearings do need to be replaced , or just go with speed master stuff

I dont think traxxas got it right with the Spartan, but then again, its not like most people that own proboats or aquacrafts are running them in their stock config either.

[Darin Jordan]

Guys... I had a LONG talk with teh PB team today, and discussed your concerns. The experienced NO issues running 6S in thee boats. We didn't just throw a 6S sticker on existing equipment... It's a NEW ESC, and, once again, the MOTOR doesn't care. These are NOT unproven combos... YOu guys have been doing this on lessor equipment since the original BJ26 was released...

I have been given permission to setup the sample IM31v2 with a 6S combo and run it... at the Nats if I want. Would have to run in Q-Mono or Offshore, which would be suicide most likely against the big equipment that races in those classes, but I'll take it anyhow and at least beat it up in open water...

If people go back and look, they'll see that a bunch of us were completely ridiculed for pointing out that the "Titan", as it was originally called, was NOT going to perform as it was advertised, and would, in fact, do exactly what it does. It was clear from the specs. Shouldn't have surprised anyone. And yet, it still SELLS like crazy! Is that Traxxas's fault?

I remember that thread... if I'm not mistaken a vetern member here also runs at the pond they use and offered advice to them, which they ignored.

Lots of people run stock aq and pb power. Spec class racing bro... lot of non-racers do as well. I wanna bj29 to beat up stock.

Noticed it was a new esc. I know folks have been beating the pb1500 up on 6s and it is a great 6s motor, the 1800 is just little hot on 6s (jmho). Just my 2 cents. Darin I'm not trying to give you hell or anything on this I don't think any of us here are I would hope we're all friends by this time, just discussing concerns that's all. I for one am hoping the new boats kicka$$. We know even the spartan castle motor which is 1800kv (lets not even talk about the 540xl feigao 2pole, that's was just a retarded thought) is having some issues on 6s. The PB does have the extra 2poles in its favor but you can see what we're concerned about.

It would definitley have to run a small prop on 6s with a 1800kv motor...no getting around that without majic.

Does anyone know what prop the bj29 is going to come equipped with?
