I am interrested in buying a RF4. Anybody who flies them can tell me
more about it?
Performance? Where to get parts? etc...
Thanks

Nearly a month ago I reported on my Tost brake failure on landing.  I
finally was able to get the plane to someone knowledgeable (Tom
Stowers) to look at it and the answer is that the brake was
incorrectly installed.

Subject says it all.  Discussion in the Mechancal Vario thread led to
some suggesting that I should get an antique Piep Audio vario that
would plumb in with my current mechanical vario.  I think they are
right, sounds like just what I need.  Anyone have one laying around

I have a mechanical PZL vario that indicates -0.5 kts while sitting
still and I would like to zero it. Does anyone know the proper
adjustment procedure?
When I take the glass off I cannot see a place where I could put a

are about to do our first brake job.
Thank you for any inputs.

I am getting ready to replace the panel in my Ventus B.  Are there any
standard materials (especially the core) and recommended glass and

This is a fixed panel, does not pop up when the canopy is opened.

Unfortunately, my last pair died at the New Castle contest, and I
can't seem to find the source anymore on the net.

I would like to know what for does WinPilot use pressure altitude?

so what else is there that pressure altitude is good for? I browsed
through the manual but I could not see any references.

I have one in my newly acquired Ka-8, and one in my
spares drawer.  Sorry, but it is going to go to one
of my clubs ships sometime soon.
RICO also made a stand-alone like the PIEP.  You might

Ok, I said I'd do this for a friend who is building his own
ultralight. He wants to design and build( me helping) a sailpalne that
fits the ultralight rules and is able to launch/sustain with a power
unit, he'd prefer electric. Any ideas or comments? Is ther anything

I'm considering Horton Stack doors (the type that fan-fold to the
side) for a hangar. One question is the expected lifespan of the
fiberglass panels.
If anyone has direct knowledge of this brand in actual use over an

PIK 20 D owners, can you give me some advice regarding how to
lubricate all controls? My rudder pedals are pretty stiff- I have to
press pretty hard to move the rudder. Is there any way to lubricate
it, or is that normal? Also, I have a problem with the horizontal

I have heard from time-to-time that Sun Tiger sunglasses work well for
soaring.  Since I fly within 30 miles of the 1/10th busiest airport in
the world, anything that will increase my chances of seeing another
aircraft is something I want to take advantage of.  It also turns out
