Thank you, guys.
All parts made in Solidworks 2009 , so I can send all project via e-mail.
It is a lot of work to make dimenthion list of all parts.
Ray, I use copper bushing for steel rods to prevent friction. Abit lubrication there.

I have to go get parts to build a new pc today. Then I can re=install solidworks and maybe....

I've been without a decent pc to do 3d drafting too long. This is what I do for $$ too.

Dimensions I will work out my self then, once I'm up and running. thanks for the drawings, superb!

SolidWorks is one of the best programs I have ever used. I get more hours per day, 5/7 days per week, using SolidWorks then sleeping.

Ahhh, that is bad Serge! This happens allot at Hobby City.

That is why I decided to use 3S and 4S and 2800 kv 4pole motors, space is limited.

Maybe 4000Mah will fit. Sorry to see this happen, that would have been nice run time too, low amps higher voltage. Nice.

I was thinking almost the same thing.

I think I will try to put my akkus in the sponsons too, better stability.

If I had noticed earlier in my shopping that you used 11L motors and 5S akkus, I may have followed you in power plant.

You spent much less than I did on motors. I still may try 5S too but with UL-1 Aquacraft motors.

What props were you thinking of running?

Hi Ray!
5S for my 11L motor is a lot of power. Normaly should be 4S for fun. But I want some more in speed :-)
The props are pairs L,R of Octura X442 and Graupner 40mm

Hi Serge, what is the small diameter for in the middle of each steel shaft?

Does it hold lubrication?

Hi Ray!
It is for securing screw.
It is for saving shaft and props in case of braking flex shaft.
It is the same as the photos

Hi Ray!
Yes, I`v saw it. They are huge, and they haven`t place for the rope.
I try to show you main dimensions in millimeters

Rull, have you measured your COG on this hull yet?
to me it looks to far forward with the batteries in front of the motors...
it could be around 40% or more

I would start my COG on this hull at 35% to get a feel for it then moved to 30% and less once it's set up good..
the batteries do put alot of weight forward, and can produce alot of drag on the hull, pulling more amps than needed
