Maritimo build

[Jesse J]

Any updates from Bonewar?

[Jesse J]

I did a trial with that one 4 blade CNC I got and it cavitated to high hell, not even onto a plane. Granted I only tried one set up on my DF33, maybe it would work on a cat or hydro

So unless we have them cnc'd after one of the tried and true guys, like X640, M445 and others, I don't think we would be very happy captains. I don't know how the cnc process is, but if you could reproduce a left hand prop, then in theory you should just be able to invert the bad boy and be makin twin roost before you know it.

Peter? is this possible/feasible? Sounds like a really important application and I bet there would be a slew of interested captains out there...

JESSE THIS IS ONE I COULD FIND QUICK, BUT THERES A FEW OTHER THINGS AROUND HERE THAT HAVE BETTR EXPLANATIONS, I.E OUTWARD PROPS = MORE STBILITY, INWARD= SPEED!THIS IS A QUOTE FROM BONEWAR ON HIS BUILD..." Calcagno 45 at the moment I'm running counter rotating inward x 442. I tried outward spinning props but the boat did not like them , made her real hard to turn and seam to lift the back of the hull . I also have tried a set of x440 both left rotation , same again the cat did not like them, i had to compensate 35-40% rudder just to get her to drive straight. So i will be running inward rotation . I've got a few very nice props to try out , so i will keep you guys informed how they turn out. BONEWAR "

Well ill run the props inward so the lefthand prop will go on the right side.. I would think two lefties would create a huge torque roll also with the power it will have..?how about the cnc guy? Cant we have some right and left hand props cnced...???

[Jesse J]

OOOOO will it be hot! You will need to add some flames on the bow and fire proof suites for the dudes driving.

Now for a question: How bad would it be to use two Lhand props? Is it super critical to go counter rotating? I just wonder how bad the prop walk would be on a big rig like this. Have you read anything?

With the counter rotating, which side does the L hand go? My instinct would put it on the left side, but what have you read/heard on this?

Go for it, get the bath filling and take pictures too!

Ahhhh, im speaking with egneg via pm's and finding out about my options? None... 442's its gonna have to be , i was thinking the same as you. 438/440's but i guess theyre not made in r/ handers... L a m e ! ! ! ! ! ! C.f? Im not sure they would handle the weight and flex of the boat and rpm...i knew id be pushing it with this set up so thats why 240's were a must and thats all im waiting for to get her wet!!havent done a bathtub test yet but actually thought about it yesterday. I could simulate the 240's w/ some 200 amp hi models...well, egneg is going to do me some 442's detounged( as his suggestion)..im hoping this isnt going to be too hot of a setup!!!

great description. you definitely want a "paint only" room and lots of patience. great work wolf, I hope to be able to see the beauty in real life as we streak down the strait away.

As for props, what motors are you using? Those are 2700 KV puppies on 15V so about 40K rpms - holy canoli batman. I would be tempted to start with either X438 or X640s. Unfortunately we are limited by which sizes are counter rotating. For my build, I chose the KV motors based on the props available - 442 and 447 and bigger. So, its a good thing you have two Hydra 240s you will need them. Looks like you are pretty much stuck with 442s, unless you go CF which come in 40mm also.

With my 1500 KV motors, I like the flexibility of doing 4S (22K rpms) and bigger props for more scale speeds and 5-6S (28K and 33K rpms) and the smaller props for the ballistic crowd spraying lets get outta dodge runs.

I have two pairs of 442s with Egneg getting sharpened and balanced as pairs for the truder.

Have you done any float tests? I would like to see how she sits. How close to maiden voyage?

good idea.

Thanks, thats great information. I've painted a dozen or so rc car bodies but this will be my first time painting a boat. I'll keep it simple for the first one.

i prepped the hull by using scotch brite and sanding in every dirrection, not circles. filled seems blemeshes w/komb pot putty and sanded/ block sanded perfect with 400/600 grit. sprayed transtar 2 in 1 primer (can).1-2 coats or until perfect -no pits, blemeshes. sanded one last time with 600 grit lightly to make smooth as can be. tape off unwanted paint areas..now as far as paint goes, i go to "the paint store" wich carries all the highest quality paints and they can help. i use PLC, house of kolor and other brands. this was a 3 stage paint job so i spayed a silver base PLC 1:1 course-silver w/ exempt fast reducer, 3 coats 20 min between coats, and a transparent orange1:1 w/exempt fast reducer 3-4 coats again 20 min between coats( stay away from transparent until youve sprayed a couple boats) . its a little challenging to get even coats as its transparent. the more coats the darker the color.. crazy in the sun!!!!!!!! wait an hour then spray your clear. i do one fat even coat. if done right you wont need to color sand it at all , as the maritimo. (stay away from drips,.) for the clear it was a PCL super- pro clear with super- pro clear multi-panel catalist . as clear coats i use dont have the hardner built in the paint .LET SIT ((hang)) FOR 24 HRS OR UNTIL DRY. GOOD LUCK AND EXPECT DRIPS IF YOVE NEVER SHOT PAINT BEFORE. USE A REPORATOR SUTIBLE FOR THE JOB WITH ADAQUIT VENTALATION BUT AS TO NOT STIR UP ANY PARTICLES INTO THE AIR I.E PAINT. USE STRAINERS AND HAVE ACETONE FOR CLEAN UP, BUT BE CAREFUL AS IT WILL REMOVE YOUR BEUTIFUL PAINT JOB! I WAS TAUGHT HOW TO PAINT/MOLD/FIBERGLASS/EPOXY, HE ALSO GAVE ME ENEPH PEARL(S) TO LAST ME 30-40 BOATS... HIS NAME IS JIMMY-C . HE PAINTED MY FIRST BOAT AND $500-800 A BOAT WAS TOO MUCH AFTER A WHILE. HE TAUGHT ME WELL.. THERES DIFFERENT WAYS AND PAINT , BUT THIS IS HOW I DO IT. HERES THE GUY WHO TAUGHT ME ALL I KNOW www.kustomart.com/

[knpc]

The boat looks great. Any chance you could tell me the process and type of paint you used. I just got a hull I'd like to paint.
Thanks

Jesse, did you see that 75mph twin mean machine?? Ohhhhhhhhhyeahhhhhhhh.....

Hey where was that - where was I? missed it...

[Jesse J]

Just watched your vids, nice! those look really good on the water - I think you might have a bit too much air under your hull. Those shallow vees probably need more weight or possibly just more weight forward. Your strut angle looks pretty good and they look really cool skittering along!

when the cat gonna get some wet? How long is that - I didn't see it in the thread.

Isn't there any better place? a nice lake or something where you can really move and let it all hang out?

Wait, did you say for your honeymoon you stayed in a brothel? how was that.... oh ya, "don't ask don't tell...." I didn't ask.
