The Black Pearl P Sport Hydro 2017

[Shooter]

Hi everyone. I made some changes to the boat this year, so I figured I’d start a new thread for the latest build. I’m still maintaining the original goal of ‘stability’ and it still has the integrated FE motor mount.

V6.2 Changes:

>The overall height has been reduced about 8mm. It’s a bit sleeker looking now and can still package (2) 5000mah batts.

>The ride pad width has increased by 5mm per side. I’m hoping this will ‘hold up’ the boat more with the heavier, higher capacity batts. In addition, if anyone wants to build up the sponsons to run loose (many have done this), you could follow the outer angle and still have decent ride pad width.

>Added support under the deck between the last frame pc and the tips. I noticed there was some flex in this area on the last version.

>The tapered air bleeds will remain unchanged.

Some photos of the previous version and a link to the previous build and vids below....

BTW – I’m all ears to better build methods, so chime in if you have ideas!

Here is the frame, tacked together with CA. It’s very easy to build in a ‘twist’. Wax paper with gridlines is about the best way I’ve found to ensure all the angles are correct. A center line alone is not nearly as robust. The frame will be epoxied and glassed later.

I've been using this super long sanding block with coated ceramic 60 or 80 paper (belt sanding belt cut to size and adhered with 3M spray adhesive). This takes material off quickly and makes an easy job of sanding surfaces flat for the sheeting to be applied.

Finished frame, minus decking. I added about 1/2oz of west systems into each sponson tip. This makes it possible to easily pierce thru club bouys and other boats.

I started sealing at this point. I glassed virtually every seam and corner. I still don’t know if this is absolutely necessary, but all of my boats are still in service, even after major collisions. I’d love to find a better way to do this, so please chime in! Some type of 'spray and done' would be nice!

I also added the turn fin mount. 1/4" aluminum.

I ran the NEU 1515-1Y for years, so it's time to try something new. Here is the NEW custom wound motor for the 2017 season!

Do you actually lay cloth into all the corners and seams, or just epoxy or resin.

Hi Bob. Yes, I lay small pcs of cloth at each corner. I usually cut the cloth into small strips. I use the wet brush to dab the cloth, pick it up, and place it at each corner. Then I wet it out when it is in position. The hull is very strong when complete, but I'm not sure it's necessary.

BTW, I use very thin glass. It easily follows the shapes of the contours. Multiple layers creates a very strong bond. I've been doing my stuffing tubes like this (see attached). It looks clean and it's extremely strong. Learned this from Mike.

It matters. If you hit even small stuff wood boats are so rigid that the weak spots will show themselves pretty quick. I'm going to use this method in future.

Do you do multiple layers at one time or let dry before next etc...?

What size can and will you tell us approx KV? I'm not going to get any custom motors thats for sure.

Do all TP's now come with gold front plate? I've seen many different versions of TP Power motors on Ebay.

Nice job, doesn't even look like there is any cloth. It's got to be very painstaking, a trial to the patience to be sure. My compliments.

Pete nice building and I'm pretty sure your boats last for long.Thanks for sharing.Gill

That build looks great.
Is there a Motor ESC combo for this class that would be competitive while not breaking the bank?
