Anybody have a rule of thumb that helps break wind speed/dir into its crosswind
headwind components?

Interesting stuff... I wonder if aviation homebuilders could benefit
from 2-stroke engines made with this stuff? Comments?

For those of you unaware the FAA has issued an emergency AD
(2004-06-52) on March 18, 2004 that requires any R22 blade older than
10 years may no longer be used. The basis for the AD is questionable.
Little if any documented research was done to verify that the age of

Does anybody know how to mathmatically tell where the balance point
should be on a NACA 63-015 airfoil?  On a single number NACA airfoil,
like NACA 0012, the number represents the balance point in percent
from the big end.  With two number airfoils, how do you figure it out?

What are some good, reputable schools for a 700 hour fixed wing pilot
to go and get some helo training?
And what are some good sites for used helicopter sales?

I recently had a vision - in fact, it was the week of the Wright
Brothers 100th anniversary - for what it's worth...  single occupant
VTOLs...
Look at the quicktime video and tell me if my idea has merit.

I'm not a helo pilot but will be embarking on that path in about 3
weeks when I start ground school.  I'm trying to get a little more
info on the physics of helicopters and have found only a very basic
"primer" at mrfizzix.com.

I have had someone recently tell me that they fly a bell md 750 and a agusta
hpr45   anyone ever heard of these?  I am wondering if the guy gave the N
numbers instead of models.
Thanks

If all you've ever flown (seriously) is helicopters and 99.99% of your time is in turbines, how hard is it to transition to fixed
wing? (not asking FARs, just practical stuff)

On another forum, the question has been raised as to why the pilot in a heli
usually sits on the right (excepting tandem cockpit arrangements,
obviously!), when in a fixed wing aircraft the PIC sits on the left. Does
anyone here know the definitive answer? In fact, IS there a ...

Over the past weekend in San Diego, an 84 year old man decided to
unstrap and get out of the aircraft while on short final. It killed
him of course. He was in a biplane but it reminded me of some
incidents when I had passengers who became the emergency in

I am going to book a helicopter pleasure flight and I would like to
know if anyone from the UK has used this seemingly FUN company

Hello NG,
I'm looking for the type of helicopter, that was the original for the
"Airwolf" of the movie. IMHO it was a "Bell", but how it's exact name of
this model?

 I was told recently that a used R-22 Beta goes for around $120-$140K.
If this is true, why are they so much more expensive than prop aircraft?
Thanks.

I have a few questions about gyrocopters and was wondering if any gyrocopter
"experts" were here to answer my questions...
Or does anyone know of any other internet spots that would be more suited than
this one?
