dave,

the boats are my own

dave,

the boats are my own design...

but they are very similar in design to the graupner jetsprint...

Well Larry!! http://www.subcommittee.com/forum/icon_rolleyes.gif http://www.subcommittee.com/forum/icon_rolleyes.gif http://www.subcommittee.com/forum/icon_rolleyes.gif

Well Larry!!
I am hoping for the best!!
And Mr Ivan Sir! Mr Teskey said the same thing.
BUT!!! If you turn it to the side it is through the side of the sub.
In my best Scotty voice, "I cannott du-it-captain"

Nice little boat Tim!! Good job!! BD.

I made myself some flex

I made myself some flex cable seal assemblies today on the lathe.
The end with the seal mounts inside of the Otter box and the flex cable end will run out to the thrust director. BD.

nifty !

I have been working on

I have been working on mounting the Otter box now that the power units are in.
I was able to get the cable inputs lined up with the box and still fit in the hull. The box is tilted slightly foreword but that is OK.
I ordered a few different sizes of silicone tube today for the seal in between the box and power cylinders. One of them should work.
I am a firm believer in the theory that with a little imagination and some K&S brass stock there is nothing you can't make.
I made two slick simple servo connection adapters today.
They are adjustable and with the seal assembly mounted in the Goop allowing it to move I should have no problem with the servo arc.
It looks like everything is going to fit in the Otter box.
Very cool!! BD.






This is an interesting fixture used to hold the seal assembly while the Goop is drying.

Today I got the servos

Today I got the servos mounted and they are working OK.
I can see why these Otter box's are good down to 100'.
The plastic is very very thick!! BD.

dave,

how do you plan on

dave,

how do you plan on attaching objects to this otterbox? is it a plastic that glue will stick to, or will something else need to be done?

[bigdave]

The Box is made from

The Box is made from ABS and seems to bond with CA very well.
I just rough up the material with some sandpaper. I really have no high stress bonds to make. The Goop will bond to almost anything that I used on the seal assemblies. The box is very well made. BD.

Dave,

Looks Good. Your build has

Dave,

Looks Good. Your build has shamed me into updating my build thread of Rick's 14 inch FS1.

You may want to take a peak at it, at least to get an idea on how much foam these things require. Also for the sub to be stable you will require the foam to be as high as possible. At one point Teds FS1 would actually would flip over on sharp verticle movements.

Hi Ben,
Actually that

Hi Ben,
Actually that is what I am hoping for.
I am trying to keep the weight as close to the center as I can so I will be able to control in any axis. Pitch, yaw, and roll.
Just like a airplane but underwater.
You can see in this new photo the linkages I am installing to control the thrust nozzles. They are set up like a V-tail so pushing the right stick F/B will tilt both nozzles down or up. Then moveing the left stick from side to side will move one up and one down to roll the sub.
The left stick F/B is the throttle and right shick side to side is steering using another V-tail mixer on the motors.
This is my plan anyway. BD.

[bcliffe]

Cool, well ignore what I

Cool, well ignore what I said then. The only way Ted got is boat back over was with human intervention ... he didn't have enough speed to flip it back over.

Thinking that won't be a problem for you though.

On a seperate topic .. do you know a source for a GW/IPSD-RXC-BS that would actually ship to Canada. No one up here seems to be able to get them, and I can't find a store in the US that would ship to Canada. Thoughts?

Cheers
BC

Hi Ben,

Hi Ben,
I sent you a PM. BD.

I got the mounting of

I got the mounting of the Otter box done today.
I have been able to mount everything to the stock floor section supplied with the kit. I was not going to use it at first but it was quite strong when glued in so I decided to give it a try. Althought far from being done if all goes well I may be able to do an in water leak and power test tomorrow. BD.

Looking REAL GOOD Dave

I cannot wait to see Her finished.

[bigdave]

Well today she hit the

Well today she hit the water for the first time, or at least part of her did.
I have the R/C system all installed and set the bottom half without the top info the tub. I just had to test the drives and check for any leaks and see how she sat in the water.
The results are,
No leaks!
Massive thrust!
She sat her fanny right on the bottom!
But it looks like she will not need much in the way of flotation for trimming.

I am working on a short video of the nozzels operating. BD.
