Darin's 22" Wild Thing Mono Project

[Darin Jordan]

Hey Guys... Been working on this for awhile. Getting close to being finished...

This is a 22" Wild Thing mono hull that Brian Buaas layed up for me using a carbon/kevlar layup. I fabricated everything else...

Going to see if this is a suitable replacement for my Maus MicroBullet for N1 and 19T Mono. Has a deeper V-Angle so it should work better in race water, but we'll see...


It's been sitting around in the state shown in the last pic here for some time... I started working on it again last week...

[Darin Jordan]

Last week, I got the strakes added and finished up, and I've spent the last couple of evenings getting it painted and the stickers on... The plan was to paint it pretty much the same scheme as the 32" hull I just finished for P-mono... with a little twist for the different hatch... Here is the result...

Darin, as usual awesome looking boat! Great job.

Looks great Darin. I presume that is a carbon fibre stuffing tube support, with an aluminum insert. What are the reasons for this, apart from perceived strength.

Douggie,

Actually, it's a carbon fiber flooded shaft log, with the forward end sealed with epoxy about 1/2" in or so, and an aluminum stuffing tube glued in place at that end to support the teflon for the 1/16" wire driveshaft. You'll see how it works more clearly on the next set of pics, but basically the stuffing tube is only attached to the hull at the forward end, kind of like on a Hydro, so if I want to move the strut up or down, the stuffing tube gently moves with it. The advantages to this arrangement are obvious and numerous. Makes the hull VERY adjustable! You can sort of get the idea by looking at this earlier picture of the hardware being pre-mounted... (see attached pic) I can now move the strut up or down within the extents of the carbon (or brass) "flooded shaft".

I used Carbon fiber on this one instead of Brass, like I did on my 32" version, because I was trying to save as MUCH weight as possible, and, hey... Carbon is KOOL!! :D

Thanks Darin, that is a very neat design. Does it work on high power/torque applications as i feel the teflon tube must take a beating or does the wire drive resolve this? I have no expreience with wire drives and i know they are often the racer's choice

Brian Buaas and Paul Pachmayer showed me how to do this last year... It works great...

I normally run the inner stuffing tube all the way into the strut nose. On my 32" WT, the brass does just this and supports the inner teflon (yes, I still choose to run teflon...) tubing just like any other stuffing tube...

For the smaller wire-drive setup, the wire isn't that long for a mono and can be run exposed if one wants... I have the forward end of it supported inside of brass tubing, then the last 4" or so is just the teflon into the nose of the strut. It's all contained inside the flooded shaft, so there isn't really a risk of damage.

I'll get some pics tonight to illustrate this better...

I like it Darin you blended form with funtion very nicley. I see you used carbon planking. I love that stuff & @ 6 bucks for foot it's not that hard on the wallet. Let me know its running weight when it's finished please.

DONE!! Powered her up tonight and set all the initial trims... Weighs in at 1lbs 15oz Ready to go minus the batteries... About 2lbs 8oz with a 4500mah 30C pack. Balances right at 30% with the packs centered in the adjustable area...

I added the J-Hook style water cooling pickup because I wanted to be able to remove it if I found it unneccesary. I didn't run water cooling on my Maus N1 boat, so I'm doubtful I'll ultimately end up needing it, but just in case, it's there...

Also, I'm using a B125 ESC w/o water cooling plates just because that's what I had available in a BL ESC... I do have a B80 in my 19T rigger, which I'll likely use in this as well. That will shave some weight as well. But then, I don't think it's too heavy to start with, and with the props I'll likely be having to run, the weight might help.

That's about it... My batteries should be here tomorrow and after that, we'll just have to run it and see how it goes...

Impressive Sir!!!!!!! Now for the million dollar question. Where is the Maus hull going ?

Impressive Sir!!!!!!! Now for the million dollar question. Where is the Maus hull going ?

Thanks Tom...

As for the little Maus... NOT A CHANCE! The first place it's going is the the 2008 Nats in California in two weeks, as a backup to this one, since I KNOW what it'll do! Second, it's my son's boat, and he'd kill me if I got rid of it! Finally... it won the 2007 Nats N1-Mono class... Just can't part with that!

[Darin Jordan]

One more shot... Here's a look at how the strakes I added came out... I'm starting to get better at doing this (adding strakes, that is...)... These turned out pretty nice. I layed them out on the hull a tad differently than I did on the 32" boat... We'll see if it works out.

[Ctonez]

you are the StrakeMaster! as well as the Rattle-can King...how do you keep track of all your titles?

I aspire to be able to do strakes as well as you some day...I need a few more tools first though!

[SJFE]

Just can't part with that!

I didn't think I had a snowballs chance but I had to ask..lol Of all the boats I have unloaded the bullit I bought from you stands out as the biggest mistake. I still keep my eyes pealed for one. It's my white whale.

An yes you are the Strake master!!! I wonder how a set of them would work on a SV??? Hmmmm

[Darin Jordan]

...I need a few more tools first though!

Tools???

All you need is:

1) A saw or Xacto to cut the wood stips to length
2) Accurate measuring rulers... I use a 12" and 18" machinist scale and a square
3) A decent bondo/filler applicator with a nice flat edge
4) LOTS and LOTS of SAND PAPER, and plenty of Elbow Grease!!


I use Poplar wood scraps off the ends of furniture quality poplar boards that are trued and square, then I use Super 77 Spray adhesive to glue on quality sandpaper to the blocks, usually wrapping it around 2 or three sides to give me the ability to sand corners, etc...

Then I just SAND AWAY... That's the part I HATE doing, but it's the most important to get right...

Doesn't really take a lot of tools... just a lot of patience, both from you AND your WIFE!!
