Similar question: I'm just about finished building a vac system and am
thinking about bagging my first wing. How do I bag a triple taper (Shumann)
wing? The surface has got to really look bad if I fiberglass wrap every
transition like Olly was talking about after the bagging. OTOH, aligning
Just got the short kit from DCH for the Sagitta 900. Are there any
tips/improvements for this sailplane??
Thanks --- Jack Dubich
Yes, The bearing loads on the tube for the wire joiner of the flying stab
are more than the surrounding wood will take. Eventually the stab will start
to wobble
I just bought a 20' crappie pole in Sears for $20. One could use it for
thermal indicating streamers or the five sections would make nice tail booms
for every size sailplane from hand launch to crosscountry.

I looked in the back of the kite catalog I received yesterday and
As a basic know-nothing on this topic, I'm confused.
I can understand how one type wire may have more resistance and require a
higher voltage to get the right temp, but power? Power relates to heat
output and should be sensitive to factors like cutting speed, wire length,
material being cut,
Carbon fiber rods are available from various kite suppliers like In to the
Wind Kites and Gone with the Wind Kites. They come in 48 inch lengths and
various diameters up to 1/8 inches. There are also thick walled carbon fiber
tubes available in larger diameters. The carbon fiber is very strong
For about a dollar you can make a fusible link that will protect your wing
from folding on launch. It consists of a snap swivel, a welded ring and a
few inches of monofilament selected for the desired breaking strength. The
snap swivel connects to the ring on the end of the launch line and the
Yes, there is the rub. You have to know how strong the wing is by testing
one to destruction or asking the manufacturer. If the manufacturer doesn't
know or won't tell buy some other product. Then use the next smaller size of
monofilament. Not all full house 2-meter wings are the same strength.
The main thing is the angle between the wing and tail. Their relationship to
the fuselage reference line only determines how the fuselage lines up with
the airflow and that determines how much drag the fuselage produces if it is
misaligned by about plus or minus 3 degrees. Because the fuselage
The Airtronics RD6000 allows you to switch from one program to another in
the air by the flip of a switch. This feature allows you to try out a
modified program in the air at a safe altitude. Even more important, it
allows you to put different flight modes on each of the switchable programs,
Title: Re: [RCSE] push rod install tricks?
Put the two push rods casings in the tail boom and see what size balsa fits between them with a little clearamce. Find a stick of soft (light) balsa the right size and wrap the push rod casings to opposite sides of the balsa stick with thread. You can
A friend of mine, Jim Scollen has built an Olympic II which he wants to fly
in Nostalgia competition.
He has built a strong spar that will take a zoom launch but, the wing tips
are not torsionally rigid enought even though they are covered with 21st
Century film. They flutter on a hard launch.
I think you may be playing with the wrong parameter. The wire temperature
should be set to produce the maximum number of threads trailing the cut but
not so hot that it produces an orange peal texture to the cut. When you get
the temperature right leave it alone. I cut at a much higher speed with
Hi Gang,
I have been flying gliders for over 30 years. I have heard of many
unwritten guidelines for flying. Like at contests, "Never fly over the Pit
area". I am taking an informal poll: "What ind of guidelines have you seen
used in all the years of your flying?
Thanks in advance.

How to build a "home built" wing with equal strength and lightness of a
hollow composite wing?
Any ideas?

Hi Erik,
You can come close to the strength and lightness (but not the accuracy) of a
hollow molded wing with the following type of construction:

There is no need to complicate the vacuum bagging or any other epoxy process
with alcohol. Epoxies are available in a variety of viscosities and some are
water thin. Aircraft Spruce and Specialty, Aerospace Composite Products,
Composite Structures Technologies, Fibre Glast, Fiberlay, and marine
Just hang a weight on the brake arm. About 8 ounces should stop the drum
almost instantly. If you don't have a brake on the drum, get one. Branding
the forehead with a "K" for klutz will help identify the kulprits.

I just bought a Spectrum with an RG15 airfoil. I was told it was an
S3021. Basically an obechi over white foam 104 inch wingspan. Nice
fiberglass with Kevlar strip t-tail fuse. How will the RG15 fly
compared with the S3021.

There was an article in R/C Soaring Digest a while back, detailing the
construction of a hot box from aluminized insulation board. The board was
taped together with aluminum duct tape. The box sat on the workbench over
