That's 4S and it's a 40mm TP Power motor about 2200kv I think??
An other "P" Sport on the table.

Hey Larry, I love this build.
I just got a Black Pearl kit from Pete and am excited to get building my first electric boat (I typically race gas and nitro). I have a few questions about your build if you don't mind sharing your secrets.
1. Which pieces did you carbon laminate and do you think in retrospect that it was worth it structurally?
2. When you carboned over the openings in the main compartment, did that end up sealing it off from the sponsons? I am considering doing this and adding some drain holes on either side.
3. It looked like your motor and strut are off-center. How far off-center? Do you think that made a difference in your boats performance?Last edited by Jarcaines; 09-22-2023, 04:19 PM.Comment

Tyler's boat has no laminate and no offset in the drive line. He had perfect heats with it at the CanAm. I can't say it was the boat though. I mean.....it's fast but the little bugger can drive. Super annoying.
Oh, I always try to make sure air can still get through to the sponsons somehow so they can dry out if the boat gets wet. Drain holes would do it but I know me. I'll forget.Noisy personComment

So I have question for you Black Pearl guys. Mine runs great but it won?t start from a dead stop. It?s submarines. If I pull the batts back a bit it flys off the water. We are talking like moving them ? inch back. Frustrating. Otherwise it runs on rails. Also what is your got to motor? I?m running the tried and true 1515 Neu 2200 in it. Great straight line speed bogs a bit on the corners. Don?t think I could fit a bigger motor in it.

You first give it enough power to drop the nose in the water.
Let off, and just as the tips clear the water moving backwards, Hit it hard.
I run a TP 4070 - 2Y - 2250kv, Two 4S 5000's
The extra weight keeps the nose down at full flight.
