Black Pearl II Hydro - 2020

The front part of the frame is the hardest part!

[ray schrauwen]

Yes it is. I had just enough useful clamps to do the bottom.

There are 2 parts not mentioned in the instructions and only one CAD image shows it. It's a curved wedge about 2.5" long that would be frame#7??? There is a notch in it for a stick.

Ray is this the one you are talking about on page #3?
It is also shown under (16. Deck.)

Yep, already glued down in the right place. The kit is really nice imo.

Next to build up the sponson edges and wood sticks all around

What esc is a good fit to stick between 2 x 4s 5000 packs, I have only recently bought mine and it has an older seaking 180a unit that does not allow for two packs.

No ESC is wired for two packs. You have to change yourself.

Sorry I should have worded that better, the wiring is not the issue its the physical size of the seaking, it won't fit between the two batteries, so I'm looking for an esc that is reliable that will fit between them, I was interested if a particular esc is commonly used in the hull due to space limitations.

[Shooter]

Hi Pete,

I run that same ESC (seaking 180) in my LSH size boat which has a smaller tubwidth than your full P boat. Do you have any photos? I remember you saying it was an older hull. Thanks!

[Pete05]

I have been doing a bit of research and I think the seaking 180 v3 will fit as its 49mm wide, my old seaking 180 is 70mm wide so it should get the job done. The other esc I was considering is the flycolor kraken 180 has anyone tried one of these?

[TRUCKPULL]

OK so far you have got;
2 x 4s 5000 packs,
Seaking 180 v3,

What motor, and prop are you going to use?

Larry

[Pete05]

Its already setup and I have run it in it's current state but the run time is short running one pack, maybe 3 mins and the pack was at 10% which was a bit of a shock for me as I don't like going below 30%.

The Motor is TP but I do not know the specs for it.
Prop is an Octura m445.

[TRUCKPULL]

First thing I see in your picture is;
Turn the water jacket on the motor, so the output is at the top
(highest point above the bottom of the boat) NOT the side.

The way the water jacket is right now. The water in the jacket will never get above the output nipple.
This is one of the main reasons that motors get over heated.
Also you should use a longer jacket.

[Pete05]

Thanks for the advice Larry I will get that fixed up, I just ordered the seaking 180a v3 which is 21mm narrower than my current esc so that should allow me to run both packs, I just need to come up with a decent battery to esc connection setup for parallel packs.

[Pete05]

My new Seaking 180a has arrived, how do people do the parallel input connection, I had a thought of soldering the bullet connector together in pairs and then just running the esc input wire into one of the bullet connections for each positive and negative. Or do I split the input wires off into a Y harness? I want to keep it as compact as possible.

[jaike5]

Can do either. soldering the bullets with a piece of copper wire running though, grind off copper ends. Heat shrink it up ! soldered bullets is what I use. I also dipped some, edges are thin tho, I don't use these
