Catamaran Tornado (by Schlueter) - the oldest rc-cat building kit ?

first MultiOne at Lake Garda! :wink:

note: no floating ball attached, one of those win or swim situations :wink:

Still water in the floats. May be the bow sections are pumping too much in the waves.

First aid: RX-rescue:

Time to test the automatic cunningham:

Some bear away practice:

Mast too far forward???

Yes!
Well, it’s a vintage cat, so I tried to compensate it with much rake.

Awesome catamaran. Thanks for sharing, I gotta make one of those

Caution, could be addictive :wink:

new arm-winch:

main arm-winch servo hightec HS-805 BB; 1:2 ratio, 100°
jib arm-winch servo new-power XL-37HB; 1:2 ratio, 100°

The HS-805BB is the 100° version of the hightec HS-815BB. I’ve got now the same 100° rotation angle and the double purchase at both arm winches, characteristics at both arm winches are now identical - small throw with high torque at a close hauled and fast throw while sheeting-out in gusts.

Using the old HS-815 lever the standing-torque should be the same with the new HS-805BB

because of the double throw
sheeting-out should be twice as fast and
sheeting-in should come with higher friction

At my last Lake Garda holiday I didn’t notice higher consumtion or lower power while sheeting-in at a close hauled - even in stronger wind and waves.

What I noticed was fast sheeting-out when needed in gusts, especially with the smaller rigs on those windy days. The smaller rigs are much harder to sail, you’ve got very limited reaction time in gusts. With the higher rig (in lower wind) the cat shows much sooner what’s going on when the wind picks up. As long as you are able to prevent nose dives the ride with the taller rig looks much smoother.

At a close hauled you usually get more time to ride a gust and a tall rig gives you good feedback, but in a bear away you may suddenly find yourself in a pitch pole. Sheeting-out the main more than the jib often helped to depower the rig and to prevent nose dives during a bear away.
