***NEW**** Pro Boat Voracity 36" Mono!!

[Rafael_Lopez]

Amen. That's great stuff.

Okay Darin, now you need to get him to some races. haha We'll throw a tent up for him at the next Cup race.

The Spartan was a great idea with great lines and horrible execution.

I have the desire to get out and race. What I don't have is the time to do so

Thank you to everyone for the kind words, I really appreciate it.

Darin has done a great job helping Pro Boat get to the point to where we picked it up from. We still require his help and appreciate his input while in development. He's still very actively helping behind the scenes, especially with testing. I make sure to send him pictures and CAD files of what I'm working on and he usually just sends me back drooling smileys.

Very cool boat ProBoat, can't wait to pick one up it will be an awesome addition at a HDV Saturdays...

I notice that the Voracity's hull is shaped a bit differently from the Impulse's. There's less (scale) freeboard, and the tip of the nose doesn't have the same vertical edge. Can I ask why it was done this way? Does this affect the performance of the vehicle, perhaps by lowering the center of gravity, or is it merely a cosmetic change?

[Rafael_Lopez]

It's just a cosmetic difference.

[montymike]

A 36 inch cat maybe..

[Darin Jordan]

Hmmm...makes me wonder if AQ will bring something similar to market.

I'm not sure what AQ is up to. Mike Zaborowski (Grimracer) is no longer working for them, so I'm not sure what their status is at this point...

It's just a cosmetic difference.

The geometry of the IM31 hull actually works better as the boat increases in dimension. It has an amount of lift appropriate for a 31" boat with limited power, and as you start increasing that power, it "loosens" up quite a bit.

As you grow the dimensions, however, you can push it to higher speeds before this occurs.

Or, to put all that more simply: It works better at 36" than it does at 31" (well... the keel line is actually only 29"... the overhang makes up the rest, so really 29").

I actually think a 44"-ish version for 8-10S or a Gas motor would really work well...

Rafael usually catches me while I'm sleeping at my desk... which explains the drooling.

NONE of this happens without Rafael, Scott, and the team down in Corona. I think their efforts have been amazing and if I've helped at all, I'm very happy to be a part of it all.

(OK... LOVE fest over... let's get back to talking BOATS! )

everyone's hard work is very much appreciated.thanks for putting out great products.

Haha!

My boat is on a boat, where are the boats?!

Rafael:

I posted an inquiry a page or two back, but it got ran over by the excitement! Anyway, the one video you posted it appeared you were running two 5000mAh/50C/3s LiPo in series. What type of run times were you achieving with those batteries? I know it all depends on how much on/off throttle, just a ball park would be great. That one video showed pretty hard running for 1 min before you brought it in to check speed; run times with that type of running is what I am after.

Sorry I missed that.

Hard running, just under 4 minutes with the batteries coming back at 3.7-3.6v/cell with default cut off at 3.2v/cell. The LVC kicks in pretty early to protect the LiPos under hard running. I had testers report as high as 7 minutes of run time which I assume was not all hard running. You could get an extra 30-40 minutes by lowering to 3.0v/cell and LiPos come back at 3.0-3.1v/cell. Not worth it IMO.

[T.S.Davis]

haha I'm guessing that's 30 to 40 seconds. 40 minutes would be awesome.

[Doby]

Have you guts tried it with 6S2P? How is it with the added weight?

[Doby]

Picture a 40 minute Q-Offshore heat!

One more thing that I'd like to do is set expectations. Lately there has been a lot of debate with our 29 inch hulls and the temps of the motor connectors getting near 200*. If you run as hard as I do in my Voracity videos, which is honestly how I've always tested this boat, temperatures in the Voracity will be the following:
Motor-130-140* measured at the rear end bell, not the cooling sleeve.
ESC- 130-140* measured where power wires exit the ESC, not the cooling block.
Battery connectors-180-200* measured at the EC5s.
Motor connectors-200-230*
LiPos-120-130*
**Edit** These temps are with stock prop which is equivalent to Octura X645.

I run the recommended batteries and never puffed a single 50c pack. I did puff 2, Dynamite Reaction 5000mAH 30c packs running that way. My testers run their own batteries and none of them reported ruining any of their packs. They all reported at least 1, 50+mph run on 6s. We also only destroyed one ESC because timing was set at 15*, not the default which is 7.5*. I think the boat went over 60 for a few seconds, lol. The other incident we had was the motor connectors melted the solder with a 447/3 on 6s. We didn't burn up a single ESCs testing it under "normal" use. We didn't burn up any motors either.

I as the PD, and Horizon as the Company I represent, feel these temps are normal under the expected running conditions of 50+ on 6s, for this project. If these temps seem high, keep in mind we are dumping a minimum of 5000mAH @ 50c, 22.2v, through the electronics in under 4 continues minutes. Heat is to be expected on 6s, driving like I do in my videos; lead finger. Lower voltage and more conservative driving keep these temps lower.

Thank you for the quick response, that is the information I needed. I expect to run more conservative, but always interested in 'worse case' scenarios and adjust for my personal preferences and needs.

Have you guts tried it with 6S2P? How is it with the added weight?

That is interesting, I was wondering the same thing.

Thank you for all this added information, definitely a good baseline to compare when I receive mine. I intend to try 4s, 5s, and 6s, however, I will probably end up running 5s more often to allow for a little safety net, plus play around with some props.
