    What is the max battery height at the 165mm length on the front.

      Hi Larry. Looks like 32mm. You could always shave some material off the motor mount gussets to give yourself a little more length. What batteries are you trying to fit?

      I'm going to seal it tonight. I've been using an old T-shirt to work it into the wood. Sounds ridiculous, but it's the best method I've found so far. Excellent results.

        Also, forgot to mention. I cut the top cross member of the bulkhead. I do this with all my boats. I sanded down the lower cross member as well.

          Pete - the 165mm length, is that to the motor mount gussets at the floor??

            Yes Larry, exactly. Keep in mind that the height drastically increases as well as you move back.

              A little more work on the P boat. I sealed the it with West using a small cotton rag. Rubbed it in. Starting to mount hardware and bend the stuffing tube. Hopefully I'll be priming both boats by the end of the week.

                I glassed in the stuffing tube. Many schools of thought on the bend. I typically go straight from the motor shaft and then a gradual "J" bend to the strut.

                  Love these wood build threads. My BP17 is still in the box. I wonder if there could be a way to seal the wood before laser cutting it? It sure would be nice to only have to worry about the edges being sealed when building a wood boat. I'm surprised the ply manufacturer's don't offer such a product. The premium in cost would be worth it IMO and surely it would result in a lighter boat if it was some sort of adhesive film applied under pressure with heat. Something almost like magic transparent scotch tape.

                    Hey Mike. Not a bad idea. I've considered sealing parts before assembling for sure, and think I'll try it next build. I suppose we could rub it into the wood before laser cutting, but I'm not sure if the fumes would be hazardous or not.

                      EAEE1DF4-4F24-4060-BACB-ACD47699CECF.jpgHey Shooter I noticed you cut out the former top brace I there is no problem with strength when doing that. I assume this means you will run your batteries length wise. I think I will do the same seams like it will make setup easier.

                        Hi, your boat looks nice! Yes, I remove that upper brace on all my builds, and I do run my batts and esc lengthwise. That being said, I glass every seam and joint on the boat for srength. I also think the curved hatch stiffens up the boat more than people think, and acts like a top cross brace.

                            On the full sized Pearl I always keep that top brace. One the smaller I broke it off. I'm not that concerned with the lower power and weight.

                              Hey Shooter. There's a guy on Facebook looking for a nose cone for the ul1. Would yours work for him? Here's his profile to contact him if you're on Facebook lol. https://www.facebook.com/brandon.groothouse

                                Sorry, no the UL-1 is much smaller than the original Black Pearl nose cone that comes in the kit. They are not compatible.
