Does the Australian Renesis four port come with the automatic TX
flywheel and counterweight? Do you have the same engine if you P-port
the four and the six port ? If you do than the four port should be the
choice because Mazdatrix wants $455.00 for the automatic
flywheel/counterweight combination. H. Karibian

Yes I think so.

Yes you would have the same engine. As far as I know there are
no other changes. I could be wrong.


Paul Lamar ...No rotor no motor.

As far as i know the Australian Renesis engine is brand new out of the
box,redrive fitted, cooling systems fitted,then fine tuned. I live about
an hours drive from where these engines are installed into Cobra
aircraft. The airport where i live is where these engines are tested and
flown, they run and sound beautiful.
Go to www.tomair.com.au <http://www.tomair.com.au>  then forum,then
Barry Mayne and his arrow. There you will find photos of the installation
of the engine.
If you want to know more about this engine E- Mail Tom .

First flight:
"G'day everyone,
Yep, finally got to do it.
I scared the crap out of myself as everything happed so quick.
I can't give any figures as I was too busy trying to save my arse,
if there had been any buttons on the seat cushions the pucker factor
would have neatly plucked them off.

Ground roll was good, but before I could see what the speed was it
lifted off and went almost vertical. I managed to catch it before
it stalled but it continued to porpoise badly, then the engine
started running rough. By this time i was at the boundary fence
and I picked out the paddock to crash in. It was still climbing
and the porpoising reduced so I continued with the circuit. On
downwind the engine smoothed out a lot and it was stable. It was
good enough for me to take a pic out the front. I had no idea
whether the porpoising would return when setting up on final and
was resigned to a probable crash landing. It didn't happen, it
behaved in a very stable manner all the way down and onto the
ground for ( what the CFI called ) a smooth landing.
The knees were like jelly and I thought that maybe I needed to
change my jocks but on reflection most of the problems were of
my own making. Firstly I have no idea of the take off speed, I
was too busy looking down the runway keeping it straight.
Secondly I think I had too fine a pitch setting and the rough
running was due to little or no load on the engine. Thirdly I
had been agonizing about doing the first flight for so long that
I was a nervous nelly.
The good aspect of the flight was that it was very stable in roll.
The controls are heavier than I thought they would be and the pitch
is way too sensitive.

I'm sure everything can be sorted out, after all thats what
the 40 hours testing time is for.
More later as I think of it

Cheers
a very relieved Baz"


Second flight:   
"Well, the weather was absolute crap here over the weekend but
all the rain was great.
In between showers yesterday I did another run ( cloud base
around 1500' AGL ).
Very dissapointing to say the least. Changing the AOA on
the groung certainly got rid of the vertical attitude of
the first flight but needed a pull back on the stick to
get it off the ground, after lift off it still porpoised a lot.
Setting the prop with more bite helped with speed but the
faster it went the more unstable it became in pitch. The
engine still giving the impression that it is over running,
maybe I still don't have enough pitch on the prop, I just don't
know. I throttled back to run at about 4600rpm on down wind
with TAS 110 knots and the engine giving the odd rough running.
Not at all impressed I gotta tell ya. Pitch, while controllable
was very erratic and I was glad to get back on the ground and said
a few choice words to the bird. After landing I ran it up to full
throttle and it didn't miss a beat. The only good thing I can report
about the flight is that the oil temp was in the high 70's and the
coolant in the low 80's.
There has to be a reason why its so unstable, maybe the C of G is
wrong , who knows, I sure as hell don't. It didn't try to kill me
this time so I guess thats a bonus.

I really thought it would be right this time and I could put
it up for sale before going to Oshkosh later this week but
I can't do that until I'm satisfied with it.

I will have to talk to Tom, but I will leave it until I get back.

Baz"

New aircraft design ... rotary engine....real balls :)
Cannot figure out the CG position on the ground relative to
the quarter cord point and is still willing to fly it? It is
a miracle that this guy is still alive :)
