50" Hydro Build

[Make-a-Wake]

Thanks brushless.......................its got alot left in it.................i was easing into the throttle and never went over 2/3 into it.

I have to get the strut right and maybe move the cg up an inch or two...................kinda wish i had waited to vid it now.....................but thought i'd share it. Heck, my Elam goes 53.........this thing outta hit 60 when she's dialed in!!

we are glad you posted the video anyway!!

Here's the strut setup.................not very deep............and it has a bit of positive.

Lower it and add some Neg..................?????

i would try a smaller prop first maybe a 67mm and maybe use an external water pick up for cooling ....my proboat 1/8 gas hydro has two water pickups.......if u can adjust the strut give it atry.....rember to do it in small increments ..u dont want to make it worse......i want to se that that thing fly....keep those vids comeing

[Make-a-Wake]

Thanks for the confidence boost there Ron!! I'll get her ripping if its the last thing i do!

I'm running a 63mm right now.............the motor and ESC can certainly handle it apparently.

The boat came with an external pickup, but it looked useless............barely would even be in the water...........so i took it off........just the brass tube and line. I guess i could put a long brass tube on and try it..........???

Outstanding maiden and vid

That rudder looks SUPER long!

Do you have any idea what the pitch is on that prop, or what kind of lift it has? Can you tell at all just by looking at it? I wonder if you ran a standard prop around that size (instead of a larger one cut down) what it would do. I think the big gasser props take a lot different approach to making a boat run well than the standard props we usually run on FE boats due to their lower RPMs...it might act completely different with another prop of similar diameter

I'm doing a 54" MHZ hydo and was told to put the CG at 2.5" behind the sponson not sure if that will help you

Its the standard rudder that came with it, came with strut, flex and rudder. The rudder is 5.75 inches long. Did you ever come up with a CG recommendation based on it being 4.5" back at the moment..................?

Quote Keith - "Do you have any idea what the pitch is on that prop, or what kind of lift it has?"

It is listed as a 1.4 pitch on the site................I have an Octura 1460 i need to bore out to 5mm that i can try as well.

Thanks Rick! I may have to move the batts forward........i was already sorta checkin out how i would do it earlier this evening. What power are you running.......motor/cells etc..........?

[old guy]

Mine is going to have 2 motors lol I'm going to make it with a QDHTR Quick draw and after I get it all set up I will make a motor mont for the Castle 2028 780kv I have on it's way to me now. I will run it on 10S not sure what ESC I will use but it sounds like the one you are using takes a licking and keep on ticking I just thought it would be cool to show up at a race with 1 boat and race it in 2 classes. One thing I like to do with all my boats is set up the cooling water exit so as I drive by I can make sure it's getting water if I can't see any water coming out time to come in. I was told to that my CG should be 1/2" back but I'm going to start with 2.5" that's where I was told to put my C/G by some of the Gas gusy that race these big boats. hope this helps

That boring out is gonna be a pain an introduce possible balance issues. Im beggin you to leave that alone and get a 3/16 or a 1/4 turned down to 3/16. Are you gonna commit yourself to that endeavor at every prop change?
If you runnin around 25k a 457 should be a good one to try but at the same time just looks like some balance issues to me.Nice rooster though.

[Make-a-Wake]

Thanks, I'll have to consider a shaft change possibly...........we'll see. The motor is the same diameter and 21mm longer than a 5692 leopard.

Good gracious. You could cut a half to 3/4 of an inch off that strut if it wount hit your water pickup.

Took her out again, and she got past the wobble stage which was more minimal due to strut adjustment, and got goin!. Ran great, guesstimation is near 50, but after 4 laps she stopped dead. The Strut, which has ONE bolt(never figured that out), bent forward under all the pushing pressure, and bent the double teflon tube in half, snapping the flex. I'm trying to figure out where they expceted the thrust to be applied with a flex cable and a teflon stuffing tube?

Anyhow...............ordering a large speedmaster strut, 1/4 flex turned down to 3/16 for more prop options(like the 1460 i have), I plan on bending a large brass tube to make a stuffing tube for the teflon and flex to go in..........its really how it should have been from the get go. But i have 3 times the stock power so i can be disappointed................

Next weekend she'll be up and running with the "proper" stuff.

Keep watchin' for my 60 mph run here in the next week or so!
