NEW Pro Boat Impulse 31 V3

[Darin Jordan]

Did a lot of testing with this one. Pro Boat is done messing around!

[Darin Jordan]

Please note: This power system is NOT P-LTD legal. Motor is 40mmx68mm 4-Pole, and YES, it really does do 50mph... easily.

WOW!
Very nice....
If I was looking for a RTR...This would definitely be the ticket!!!
This will be sold out quick...No question about it!
Aloha

A couple more notes:

1) Hull is from a new manufacturer. It's layup has been improved and the strength increased.
2) No Wood inside.
3) Sub-hatch has been eliminated
4) I believe that the flexshaft has been upgraded to be .187.
5) Still accepts OSE Upgrade Turn-Fins (and I would recommend those highly if you race or run in choppy water)

It's a very nice evolution of the original design.

Proboat is definitely upping their game. I just saw the innards of the new bj29 and it's much better than the original. My shockwave 26 is also much better than the original version I owned.

This power system is BEASTLY! Especially for an RTR. I ran it at in my older IM31 for the P-Mono class at the 2014 Nitro/Gas Nats (P-Mono FE Exhibition class) with an X447/3 and the boat was BALLISTIC... Would easily run away for the first 3-laps.... UNTIL... 29"-Ish hull isn't exactly perfect in "after-lap-3" race water...

They new motors and escs they are using now are ALOT better than the original stuff. The guy that's in charge of that stuff has his stuff together I can tell you that!

Darin, flex cable is 3.7mm/.150. I never broke a single shaft during 6S testing with this new motor, which is why I never went to 4.7mm/.187. 31-inches is the limit for .150 cable in any Pro Boat product though.

I'm very proud of redoing the interior of this boat. The layout is perfect and the molded plastic cant be beat when it comes to longevity. The seal around the canopy opening and the twist lock are huge improvements. It was a pleasure to be able to revamp the boat you built, Darin, and finally make the inside match the outside.

Thanks for the kind words, Travis.

Nice...but to bad they didn't make the hull a bit bigger to handle "after-lap-3" race water.

[T.S.Davis]

How long before guys are putting 6s in it? I give it 3 hours after release.

Does this have the same kind of material used in the Blackjack for innards? That was a huge improvement on those.

[Rafael_Lopez]

Sorry, I don't understand your 6s comment. The boat is 6s capable, considering the motor is 1750kv. But like Darin said, you can run 4s in it with a large 3 blade prop and get similar speeds.

The interior in this Impulse 31 is molded plastic. We specified our first test boats to have the center structure to be made of FRP, like the 29-inch cats. Honestly, it was no improvement over the wood because it was pieced together with glue. It was keyed in but it was made of multiple pieces glued together and it started to fall apart shortly after a few tests so we made the call to go this route; injection molded. The new molded plastic tray will outlast the boat. I might still have the remnants of a boat to prove that, lol.

Terry here's a pic of the black jack which I believe is the same

[T.S.Davis]

Sorry Rafael, it's a recurring theme here on OSE. If a sensible setup comes along like this one appears to be, there are always guys that want to throw more cells on it. What ever makes sense..................add 2 cells. haha

Great to see Proboat still developing and improving their products. The Blackjack V3 is so much better than V2. I'm optimistic that this will be another improvement. Keep up the good work.

We have a guy racing one in our club. It's really impressive right out of the box.

[Rafael_Lopez]

T.S Davis, I got it now, lol. Thanks for bringing me up to speed.(insert blushing smiley here)

Thanks. We really are listening and we really are trying to bring better products to the market so that customers will not have to change things, although we hobbyists can never leave anything alone.

Some of us hobbyists finally start learning when the smoke starts to leak.

[Darin Jordan]

This size is more appropriate for the general consumer. The "basher", etc,. needs to be able to fit the thing in the car, and it IS, after all, ultimately meant to be a 4S "Limited" boat...

Bigger boats require more power and more battery and MORE MONEY... :)

That being said... You just never know what may be on the way in the future... Obviously, Rafael and Pro Boat are listening!!

Rafael... Sorry, I couldn't remember which shaft it ultimately ended up with. I've never broken a .150" either, but then I don't run mine on 6S very often. Boat is small and light enough that .150 has always been fine.

As you guys can see... Rafael is truly "Da'Man" these days, and he's been working hard to get this product line to the next level. All the credit to him and his vision for the future of this stuff. These evolutions are simply amazing.

I hope the consumers get these in their hands and feel the same way. The performance of this boat, out of the box, just brings a very big smile.

My wife will be mad when I tell her I need to buy another boat.

[Raylon]

What's with the hole around the flex shaft? Never seen this on a boat before.

[Doby]

Been there for several years....called a wet well, allows for strut adjustment.

[Brushless55]

Very very cool !

[rw442]

Go figure i just bought a new Impulse 31 3 weeks ago new i should have waited!

I bought mine used 3 weeks ago. But I gutted it put in leopard 4074 1650kv and 180a ESC along with the .187 flex shaft. But I do want the yellow decals as soon as they are available:)

[Rafael_Lopez]

Hello everyone. I wanted to share a video with you that shows the new GEICO and a side by side of the V2 Impulse and the new V3 Impulse. The motor in the impulse went from a 36x60mm to a 40x68mm.

[bigcam406]

any idea when this motor and esc will be available.thinking about throwing this setup in my Fastech.

[montymike]

Why did they not put this motor in the blackjack?

[Rafael_Lopez]

Hi Montymike,

We didn't put the 40x68mm motor in the V3 29-inch hulls because we didn't feel it needed the power to be a successful product and reach the target MPH range, reliably. Because a cat is a hydro, it requires less power to get comparable speeds to the V hull. The V hull, cutting through the water, required a much more powerful and efficient motor, and honestly it was time for an upgrade in the Impulse 31 V3.

The V3, 29-inch hulls requires 90 nominal amps continuously, with the current power system, at 15* ESC timing. The same system in the Impulse required 130 amps at 15* timing and 110 @ 7.5* timing; too close to the ESCs continuous advertised amperage limit. The solution was simple, a larger motor for the Impulse 31 V3 that would bring the nominal amperage to a range more comparable to the 29-inch's power system while yielding the target speed range. The ESC in the Impulse does run lower timing; 7.5* versus 15 in the V3 29-inch so there is plenty room to push the system harder, if the customer feels comfortable taking on that responsibility.


That's probably not the answer you were looking for, but it's the best answer I can give you.




Bigcam406,
The ESC is currently available. The motor is scheduled to be available mid to late July.

My main concern is r.p.m. On 6s .

I understand your concern, and it's a very valid one. We see a mixture of customers that don't mind or care what the unloaded RPM is as long as they don't burn up their electronics, puff their batteries, and go as fast as they can go out of the box. Then there are those that don't like the high RPM setups at all because it wears parts quickly. The hard part is finding a balance that suits both customers.
