Pre-preg carbon self righting Titan 29 build

[bikergreen]

I have tried a little different painting scheme and got some action pics in the waves

That last pic is SICK! I need a boat like this for wave bashing!!

Nice water is the bottom of your rudder flat?

Yes, it is.

[Mike Caruso]

You need to round the BOTTOM of the rudder off front to back. Take your time you will be rewarded with better performance. Let me know it should help but also make's the nose run lighter so drive easy the first time in the water. Make the back side (trailing edge) of rudder sharper than mine I thought it was sharp until I took this picture. Free speed just like back edge of propeller blade.

Water tube I added to bottom of rudder is from the AQ SV27 and it is hard brass and I used a .091" drill bit to open it up. It flows plenty of water for my boat. I wish I could sharpen the back side of the rudder like I used to sharpen my Ice Skate Blades called Hollow Ground. Bridge Port and a very small ball end mill bit. I think it would reduce drag using Eagle Tree I could prove it and I'll bet it would do the same on the prop.

how sharp should a rudder be?
cut paper?

As possible you can.
I can shave my arm with mine.

[Wetter]

didn't realize had to be so sharp.
thanx.
sorry Big not tryn' hijack your thread.
just tryn' not to start a new one.
soo many of these things and stuff to learn.
now where did i put that Autoclave

[Mike Caruso]

My Autoclave is hiding on me too! HA

[lenny]

Is that a weed block of some kind,
Coming from the stinger and over the prop to the back of the bullet nut ?
I never seen that done before if so.

[lenny]

Ok sorry,

Just taking this great build in.
It is a prop saver,
Sounds like a winner to me.

[Wetter]

Hey Big what about a larger self-righting rig?
damn you're good.

[Bigbore]

That's what I made at my rudder. First pic before and last pic after rounding.
Tomorrow I'll go to a lake attended by FE racers and will see what my boat can do.

@ lenny: That's a prop saver that is helping me to understand how to setup the wire drive. My current wire drive with a diameter of 2mm (0.078") has 7 hours of work on it and I've used it in salt water too without removing and greasing each time but only every 2 hours. At the beginning I had problems with alignment to the motor coupler and the wire lasted less than one hour.

@ Wetter: Are you talking about a bigger boat?

[Wetter]

@ Wetter: Are you talking about a bigger boat?

yea, yea.

[Bigbore]

yea, yea.

It's not on my plans for the moment. I'm super happy of this little fast and furious boat capable of bashing through the waves and fast running at the lake on mirror water.

At Mike Caruso you are the man! The rudder performed axactly as you predicted and the boat at the beginning was looser than last time I tried it.
Then I've adjusted the position of the stinger, the batteries placement and the trim tabs.
At the end of the day at the lake I was happy because I was able to adjust the boat trim as I wanted.

Great build, you've done very very well. I miss my titan but it needed to be self up righting like yours, it spent too much time upside down.
Awesome work!!
