39" HPR 99 Bulletproof

[keithbradley]

I haven't done a build thread in a while, but I suppose it's time I do one. I recently started stocking these HPR 99 BP hulls so that guys in the US can get them quickly and easily. I haven't done anything on this build yet, other than solder some connectors on the ESCs.

Here's what will be used for power:

- MGM 28026 ESCs with top secret mod
- Lehner 1950LK motors (I have a couple different winds to try but 1950 is definitely the size I will be running)
- 6s lipo

The hull is laid up in Switzerland by the famous HansPeter of HPR Powerboats. It's quite strong and should handle everything I throw at it. The lamination is also quite beautiful on the inside. This is not only the fastest hull under 40", but it's also among the best looking.

The size of this hull is no accident. It's just a tick under 39", fitting in the IMPBA and NAMBA "Q-catamaran" category (Q hull length must be under 40"). It's the perfect size for a high-power 6s boat.

For hardware on this, I will be using:

- KBB motor mounts (will be added to the site soon)
- KBB servo mount
- 3/16" flex
- MBP click drives (I'm going to try to do something custom with these on this build)
- KBB rudder and hydraulics

When this is done I want it!!

I've got 6 more bulletproof hulls in stock. :thumbup1:

[depeche_mode]

LOL build me one.... there is a market for high end boats that are drilled and glued.

[keithbradley]

The EASY part of the drives.

The next part is not so easy...

The next couple posts feature some pics I took while machining the next part of the drives. For those of you not familiar with manual machine work, this is a long, precise process. I didn't count the hours, but let's just say it takes a while. :popcorn2:

:popcorn2: Very nice Keith I'm looking forward to seeing the clicks mounted on that hull

After de-burring and texture coating:

[srislash]

Well done Keith, I am all to familiar with the process. I recently made a rudder standoff on the Unimat.

[ls1fst98]

very nice. ive been eyeing the new 99 for a while. i like it a lot.

[keithbradley]

I'm in the middle of a couple customer projects and won't be able to get much of anything done on this one for a couple days, but I thought I would take a couple pics of the drives in the meantime. The transom mounts are V1 prototypes and will have a couple revisions before I'm finished, but this gives a general idea.

What is the theory in mounting this way?

[keithbradley]

What is the theory in mounting this way?

1) Looks cool

2) It's unique

3) It's strong

4) Superior drive angle, different lift characteristics.

Ok I LOVE IT!! Can you make me one and drill all the holes too LOL


LOVE YOUR BOATS!!!!!

You mean a bare hull with holes drilled for drives and rudder?

[depeche_mode]

Yes that would be a good seller for your company. Many people do not have those kind of tools and expertise to drill but are very good at assembly.

Ask your customers and see if there is a market.

Cheers

I could do something like that, but in my experience, the demand isn't as great as you would think. So many people want to find a cheaper way when it comes to hardware. Guys will install the wrong rudder on a boat and completely destroy the handling characteristics because it was $50 vs. $100 for the correct part.
In order to pre-drill a hull, the hardware being used has to be accounted for. I do this with the 45" mystic hull we sell. I have fixtures for everything. Holes for drives, rudder, and hydraulics can all be pre-drilled for the appropriate hardware, which I also have on hand. I charge $200 for the pre-drill option, and this allows the builder to just "bolt on" all the hardware.

Sorry for the lack of updates, this one is ready to go!
I ended up using a servo mount that I had laying around (made it a long time ago for a build and didn't really like it) because it was quick and easy. I plan on covering the ugly yellow wires, but for now I'm going to just run it this way.

Here are a few pics:

I dunno man, I think yellow goes well with all the black/grey carbon... makes it stand out nicely infact and are a great "color pair". Perhaps wrap the red wires in front with black...

Perhaps would go well for a black and yellow theme for paint job...

[depeche_mode]

I need this!!!

[mudl]

This build looks great :thumbup1::thumbup:

[keithbradley]

Thanks for the kind words guys.
I just took this boat for a maiden earlier this week, it ran quite well. 98mph on 5s and 114mph on 6s with no adjustments and the first set of props.
This is definitely the fastest 6s hull I've tested. It didn't take much to get it well over 100.

[RaceMechaniX]

Nicely done Keith. I hope you plan to take it out to Thread Lake and get some record times with it.

Keith: What makes this HPR hull that much better than anything else... like say a Daytona or Shocker, etc? The size ratio, steps, etc? I was thinking of modifying the steps on shocker to be similar to the mystic style... was wondering if that's been done before with any success...

It's definitely in the plans Tyler. Hopefully mother nature cooperates. I have 3 boats that should all be able to set records...I may have to choose which one I want to run most if we end up with a small window of flat water.

You can put a "Ferrari" body kit on a Fiero, but it's still not a Ferrari. If you want to experience a HPR, get one!
Out of the two boats you mentioned, the Daytona would be the closest, but the quality and layup is a million miles from HPR.
