50" Hydro Build

[martno1fan]

Sory to hear about your problems with the shafts,it sucks when things dont arrive on time or not at all .Ive just managed to get my items from Hobby king after over a month of waiting and many unanswered emails .
Incidently if you dont mind ordering from the UK dave Marles has the stepped down 1/4" flex and 3/16 stub shafts but theyre 30" long .,maybe he can get shorter ones or at least cut these down a bit to save on postage.

Back in business!

Finally got my flexshaft................this one is 1/4", no step down to 3/16, so i had to get a 1/4" prop. Went with a big Prather 270...................my crystal ball tells me it should be a good choice.............its very scientific . Cant be told i'm wimping out on prop size.............got a 1/4" dog as well.

Pic of it next to a 645...........it's a big'n.

Should be able to get this beast back in the water on Wednesday

Wow! She oughtta be violent with that prop! Cant wait to see the vid! Are you going to try to get in in some bigger water or the same place?

[Make-a-Wake]

That was just my neighborhood lake which is quite good for 35" or less boats, i have plenty of big water nearby, gonna go to one of those spots. Got my strut on and added a second adjustment bolt so there will be no movement of it at all............i think everything is in order now.

"Violent" - like the word choice!

With a gap I hope. I wanna see this big hog run.

Yep, about a 2-3mm gap for flex shrinkage......................i'm getting excited, this thing may hit mid 60's....................i'll check temps and so forth, if its all cool, i can go up on prop!

Old guy, cg is now about 3" back of the bottom of the sponsons....moved the packs up 2 inches last nite. Got the new strut on and cut the 1/4" flex that came in, soldered the cut end and it all fits very well.

Went with dual water cooling sytems since it was already made that way, just added a long brass tube for the ESC intake.........its long but will reach down into the water for some good pressure.

The big Prather has been sharpened and polished up and i should be able to hit the water once i get back from the hardware store to get a prop nut..............didnt see one on kintec's site when i got the flex.................

Will most likely have a vid guy if i can drag him away from work for a short time............

[TotalPackage]

you running a 1 p setup make?

[Make-a-Wake]

Heavens no..........not with the 2028 in a 50" boat, i have 6 batts in there, each 3s 5000 40c for 9s2p. 4 batts on the bottom and two up top.

Unfortunately my run had to be aborted for today..........very disappointed, day got uglier as it went on and by the time i got to the "big water" lake it was 20 mph winds, cold, and starting to white cap. Im not interested in running a new boat in "setup" phase in those conditions. Gonna head out tomorrow morning early before work when there should be some glass!! I was really looking forward to running but oh well...............

[keithbradley]

Hopefully you can get a video...I want to see this thing move! My big boat is mostly sitting while my 3 current builds have to share attention. Im thinking some video of your hydro may keep me held over until mines done...

No amp concerns for the 2028 turning that big prop?Did the 2028 come with any specs or parameters to put in the fe calc?

[Make-a-Wake]

Here's a much better run...........i was still a bit wimpy, could have aired her out a bit longer in the straights and been more aggressive in the turns but that will come.

She's like a V8 mustang with a 4:10 rear-end.....instant torque, and gobs of it. This is with a Prather 270.....she can take more for sure!

Temps all good with the new twin pickup setup, gonna check the mah usage when i charge up tonite.

The Castle 2028 is a real bruiser!

Live in person she's alot faster than the vid seems due to the sheer size.............pretty impressive when she barrells on by!
