Pre-preg carbon self righting Titan 29 build

[jkr]

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

[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!!

[Bigbore]

Boat Completed

The boat is now completed with a final paint and yesterday I have installed a longer rudder bracket.
In these months I've been bashing this baby in the sea and at the lake and she's awesome.
The next week end I'll try the longer longer rudder bracket.

Sweet job there!! Looks great!
Did you have to do any post cure surface finishing on the CF?
How does the self righting part work?

Looks great how does it run any video

No, the carbon fibre is moulded within autoclave at a temperature of 130°C and don't need anything once out of the moulds.
Here is the test video for the self righting feature:
