Hey Paul,
I've tried diamond, and they want nearly $20k for one motor. That seems way
too expensive.
Steve
What is the horse power and how much does it weight .
Clifton.
It is about 120 pounds and 100 HP two rotor.
One of the reasons Diamond is not producing this engine is the fact
that only reciprocating piston engines are allow in certified S-Light
Sport Aircraft.
Who would blame Diamond for sitting on this Certified rotary engine
under those
circumstances.
I spoke to a person in the FAA about it and he said we literally needed
and act of congress to get the rule changed. No joke!
We need to start a letter writing campaign on this. Find out who your
Congress person
is and write a letter. Lets get the rule changed. Discrimination is the
history
of the Wankel rotary engine.
If you write a letter send me a copy and others can use it as an outline.
Paul Lamar ...No rotor no motor.
--------------------
It actually says "reciprocating engine" there is NO mention of "piston"
in it.
What you need is to get it clarified to say "internal combustion engine"
instead
maybe somebody could get a clarification that says that or maybe
somebody already
has something to that effect someplace.
if it was to say that then all is good in the world :-)
Regards David
I spoke to a representative of the EAA or the FAA a few years OK. I forgot
which and he said the rotary was excluded. A turbine is also an internal
combustion engine and I don't think they want those. Something like "or
Wankel engine"
would be acceptable.

Australia's definition in part.
This is from the "23 February 2006" version
5. WHAT IS A LIGHT SPORT AIRCRAFT?
5.1 A light sport aircraft (LSA) is a small, simple to operate, low
performance aircraft.
With regard to the requirements of the CASRs, a light-sport aircraft is
an aircraft, other than
a helicopter that complies with the following criteria:
(1) A maximum takeoff weight of not more than 600 kilograms or 650
kilograms
for an aircraft intended for operation on water or 560 kilograms for a
lighter than-
air aircraft.
(2) A maximum stalling speed in the landing configuration (VS0) of not
more than
45 knots CAS at the aircraft??s maximum certificated takeoff weight and
most
critical center of gravity.
(3) A maximum seating capacity of no more than two persons, including
the pilot.
*(4) If powered, a single, non-turbine engine fitted with a propeller.*
(5) A non-pressurised cabin:
(i) For an aircraft operating over land, a fixed landing gear;
(ii) For an aircraft intended for operation on water, a fixed or
repositionable landing gear; and
(iii) For a glider a fixed or retractable landing gear.
(6) If the aircraft is a glider a maximum never exceed speed Vne of 135
knots CAS.
The types of aircraft that may satisfy these criteria are:
(a) Fixed wing aircraft;
(b) Powered parachutes;
(c) Weight shift aircraft;
(d) Gliders;
(e) Balloons;
(f) Airships; and
(g) Gyroplanes.

That makes a heck of a lot more sense. Now why can't we have those rules?

Paul, David,
I find it interesting that they even include gliders in the LSA
specs. You can
already fly gliders without a medical and that covers ALL gliders and
motorgliders.
I've a good friend who is a glider pilot flying all the hottest gliders,
but he
was having trouble getting a 3rd class medical due to surgery and just
stopped.
He enjoys gliders more than powered flight. The LSA glider would be
considered
rather "low-fi" by modern glider standards.
