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

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

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.

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

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

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?
