Shockwave 36 Revival / brushless build 2

[myskiis2fast4u]

So i did a test run in a tiny pond down the street and she wouldnt even come up on plane with the x440 prop. I originally had a x442 on it and i thought that maybe it was too big??? I thought this because when i would be in the hole my roms were super high and then as i planed out the roms dropped as the prop bit. I was concerned with the prop biting too much and causing a largwr than normal load on the flexi shaft. So thats y i deopped prop size.
So question is....how do i know what prop size to use? Should i be churning dead water to get up and out? Should the prop just bite and the boat wheelies????? I dunno other than buying a bunch of props. Anyone else left out there with a 10lb boat on 6s???

Both props are too small for a 36" hull. The RPM's are climbing out of the hole because the prop is slipping and cavitating.

Bigger concern, you said you're running a Neu 1521 1.5y motor. If I understand that correctly, OSE's website says that's a 1050kV motor. That motor on 6S is only about 23K max RPM, which in theory could work with tempered performance, but certainly not with a tiny prop.

Nice!!!! This is the info im looking for. I have the orig x648 that was on the nitro boat originally. Is that too big? What do u think is a good size for that boat? I could buy 10 diff props but would be nice to hone it down closer to a few!!!

I'd start with an 447 (47mm 1.4 pitch), maybe a cheap aluminum CNC that's not incredibly strong, but thin and sharp right out of the package.

First run not on video i used a x648 and that thing hooked up amazingly.....then....the prop nut came off and lost the prop....
That was swim 1. Swim 2 was the video with an x442. I have to stand in a better spot.... I get nervous around my neighbors boat. Im sure he would not appreciate an orange streak down the side of his 35fter......... Anyhow i tried studying the video and it looked like she chined on my and i just lost it... She sunk and left the nose up by the time i got to it and somehow survived. That OSE raider 150 is freaking amazing so far. Very happy thats holding so far. I have 4 batteries in her....4, 3s, 5200mah for 6s in a series and then parallel condition. I have a feeling that x447 like fweasel recommended will do this boat good.... She rips water apart till it grabs and goes. Will try and get a better video tomorrow without crashing!!!!!

Every year people die swimming after toy boats, very sad. As good a swimmer as you may be it is not a good thing to do. It sounds like you have kids with you in the vid too. Drowning because of a toy boat is not worth it. Please consider an inexpensive rescue rig or something.

I guess i assume too much of common sense for swimming. I grew up in the ocean. I have water for a backyard. Meh....anyway i still dont like swimming for boats. Ran another set of packs today and the hull just caught a weird spot and flipp3d!!! That sonicwake 36 is looking better after each fail. I must not have enough trim. Right now the tabs are even with the bottom of the hull. Maybe will try a bit more tilt to them. I can get a degree or two out of the outdrive support too. Are there any shockwave 36 experts left out there?
