DZ flying time

[JOddino]

So you like challenges.  Why not go back to a 10 cc limit on engine size or
even 7 which was proposed by an English guy back in the sixties because he
contended it took more talent to fly a smaller airplane.  He was right but
no one wanted to make it harder.  They wanted planes that flew better.  I'm
sure no one today would want to go back to 10 cc either.
One reason we went to turnaround was to get a smaller footprint on the
ground.  It, combined with 20 cc engines made the noise footprint even
larger.
There is no question that a quiet pattern plane appears to be flying much
smoother than a noisy plane but in some cases noise is good.  Try watching a
Formula 1 or CART race with no sound.  Boring.
I say keep the two meter rule and throw out the noise and weight rule.  You
will still see guys trying to make them quiet because quiet equals smooth
and light because light flies better.
Then we wouldn't have much to talk about regarding engines, pipes, headers,
couplers, tanks, bladders, pickups, etc.
We'd just go out and have fun flying.
Deuce?
Isn't it nice to be able to challenge the establishment?

Easter fun with Oddino...Hmmmmm

The problem with those DA 150's is that they draw shotgun fire and you
usually only get to fly them once per field.

It's ironic that the noise issue for pattern planes of old is now the same
issue for Scale Aerobatics.... The irony being that precision aerobatic
planes are now soooo! quiet that we are welcomed and enjoyed. Of course we
can't hear our engines so we get very good at dead stick landings....

On a more challenging note, the pattern spec's are there to be met and there
for a reason. They are a competition challenge in their own right. It is the
basis of the sport to produce designs and technology to met those specs.
Without them i.e. if they were relaxed, we would not have developed the CF
pipes, FG technology, light weight foam wings etc. There would go the fun
for many of us. Take away the size and weight limits and all you get is an
average plane...

30-15, your service....

35.5 lb of thrust
6.2 HP (although it is only rated at max output of 5 HP) <LOL>

I believe I can fly for 30 minutes on my 24 oz. tank although I've never
stayed up that long.  That is with a 22x10 prop that turns about 7200 at
WOT.  Put those numbers in your static thrust calculator.  Pattern needs to
liberalize the rules so you can use engines like my DA 50.
Just trying to stir up a little controversy.
