WAY MORE?
Buddy used the stock esc.
Yes, I know it's a weird comparison, but it does give me a little hope.
Would a positive prop angle get the rear of my hull out of the water more?

I logged around 60A on the SV ESC trying to spin a big wheel. Only ran for 30 seconds or so, things were starting to heat up, especially the motor.
You want the prop to point downward to increase lift. I believe this is in the negative direction. Also a better prop would help. More along the lines of a lifter type prop - high pitched. Or use rear ride pads.
Another thing to keep in mind CofG should be close to the turn fin, I like to keep it as close to the rear of the front sponsons as I can.

RE: Another Outrigger Predator project!
Mine is on the left side and the water exit on the right. Maybe the ideal thing is if it were in the center
but i don't know much about this! This is my first boat ever.

RE: Another Outrigger Predator project!
I'm new to the electric boat scene and I want to build a predator. I've read this entire thread, but I think I need to ask these questions anyway. I fly a trex450 heli and swapped the stock motor for a scorpion motor. The stock align 430xl is a 3700kv outrunner in a case. Can I use this motor in a predator with the 3s 30c lipos that I currently use in my helis? Should I use a 60 amp esc? What prop would you guys recommend? Thanks for the help.

Is it the fact that the boat is direct drive and the heli is geared that the components that work together in a heli won't work in the boat?
I would rather use the 3s lipos I already have, so what motor/prop would power this boat on 11.1v?

For a Predator rigger hull you need rpm and lots of it with a bit of torque as well. 30,000 rpm is a good area to be in.
Once you load the motor the rpm will go down and the Amps will go up. This is what riggers do.
I run a 8S (4400kv) Feigao on 2S via a 432 prop for 40 mph speed.
My reading tells me that the Heli motors do not have a lot of torque, you can go 3S on this motor easily but use a small prop to start with. Try to find a 431 plastic and give that a whirl.
I have made a few riggers with a lot of different motors and have a bit of experience on the water to back up any suggestions that I make.
Cheers.
Simon.

RE: Another Outrigger Predator project!
Your photo shows the servo pushrod will hit main body of servo. Also the rudder hookup in last hole will have to be moved in at least 1 hole or the pushrod will have to be bent alittle straighter. Best to straighten rod some by 2mm which won't hurt excessive movement of rod. Now if you turn pushrod upor down will createexcessive movement and ease of movement of pushrod.
