How many people are building side port 13B? 4 port? six port? Side
port RX8 motors? 4 port? 6 port?

-- Hi Paul, I am putting an RX8 in my modified Long EZ. Chris in NZ

P-port or side port RX8? four port or six port ?

Paul Lamar


It's a side port (4 inlet 3 exhaust) I am putting it in as it is
(factory assembled) for now, I may p-port it at a later stage. I will
be using a rotec throttle body (don't want a computer)  had one on my
other EZ, boy was it economical. Also I was wondering if you had a
circuit diagram for a CDI that will be triggered by a couple of hall
effect sensors ? Cheers Chris in NZ


The stock manifold is rather high but it will probably fit in an EZ.

What I have on my list of things to do is build a 12 volt high
voltage supply for capacitor discharge ignition systems using a new
chip by Linear Tech.

The LT®3751 is a high input voltage capable flyback controller
designed to rapidly charge a large capacitor to a user-adjustable
high target voltage set by the transformer turns ratio and three
external resistors.

The actual CD circuit is the same as the outboard/Vespa and the TC 3
rotor CD systems.

That Rotec "throttle body" is a copy of the American Ellison carb :)
It will work great when you get it sorted out. See notaposa.pdf

BTW sorry you guys lost the America's cup at the last race but you
have some great sailors down there. You put up a great fight. For
awhile there I thought sure you would win. Most of the sailors on the
U.S. Oracle where from OZ including the helmsman.

Fantastic 50 MPH hydrofoil catamarans. More fun to watch than Formula
1.

What a vessel and what a comeback, extraordinary.
Who would think you could loose from 8 nil up.
The poor Kiwi's will be spewing.

Wait until they get rid of the trampoline and put a big wing between the hulls :)

Yes, congrats to the team from Oz on their win for the Yanks!!

Jim Spithill is also a pilot, he and his Dad turned up for Aviation Medicals a few years ago.

I discussed with him a little known discovery by Otto Lilienthal that the wind actually rises by 4 to 8 degrees as it goes along, as a world class dinghy sailor he knew all about it. It appears to be almost unknown to flyers, but well known to sailors. It's one of the main reasons downwind landings and take offs are horrible.
