Default RE: Looking for a good first sailplane


ORIGINAL: SnitGTS

Thanks for your help guys! I'll check out the sailplanes everyone recommended and go from there.

I've seen some videos of guys flying sailplanes and some of them had a real hard time landing them, I saw that they had both the ailerons pointing up but I don't remember seeing flaps down on them. Either way, I'm assuming they used a computerized rc transmitter for that. The Hitec 3 channel I have currently definately won't handle that, anyone know of a good controller out there for relatively cheap that I can use for my entire fleet? I'm planning on getting a variety of planes and maybe a helicopter and I'd like to get one controller that I can use for all of them. Again, thanks for your help!!!

GETTING STARTED IN GLIDERS
by Ed Anderson
aeajr on the forums

Thinking of flying gliders, but you are not sure? That is how I was.

I started with electric parkflyers with no interest in gliders. Then I met
a group of guys who fly gliders. After watching them for a couple of
months, in between my electric flights, I decided I had to try it. Now I am
hooked. I have 6 electrics, but I also have 12 gliders. I love to fly the
electrics, but it is the gliders that I think about all the time.

By the way, for all practical purposes, gliders and sailplanes are the same
thing.


TWO KINDS OF FLYING WITH GLIDERS/SAILPLANES

Thermal Duration - Lift is provided by warm rising air.

A thermal is a column of warm rising air that occurs when one section of the
ground warms faster then other sections. As the air raises it draws in
more air. Think of a very slow moving tornado. Not exactly
correct but close enough for first approximation.

Slope Soaring - Lift is provided by wind hitting a hillside.

The rest of this discussion is about thermal duration gliders, but if slope
soaring is of interest, here are some links that will introduce you to slope
soaring. I enjoy slope soaring often and, on some days. I slope and
thermal. Those are great days. Most TD planes can be flown on the
slope, so after you learn to thermal, the same plane may also be able
to introduce you to slope soaring.

THERMAL DURATION GLIDERS/SAILPLANES

HOW MUCH DOES IT COST TO GET STARTED?

For about $200 you can be in the air with a real sailplane, a real radio
and a real great time ahead of you. If you already have a radio, it can be
even less of an investment.

If you get a RTF package like the Great Planes Spirit Select, $150, it comes
completely built with the radio system fully installed. This was my first
sailplane.
http://www2.towerhobbies.com/cgi-bin...I=LXVK55**&P=7

While you can hand throw the Spirit, it is really meant for hi-start
launching. Add a hi-start for about $60.
http://www2.towerhobbies.com/cgi-bin...?&I=LXE636&P=7
There are better hi-starts out there, but this one will get you into the
air.

That is all you need. In fact, with this combination you could enjoy a
lifetime of soaring and never need anything else. No fuel, no battery
chargers, no extra flight packs, nothing! OK, you replace the batteries a
couple times a season, and maybe you replace the hi-start every 5-10. This
is a very inexpensive form of RC flying.

As much as I love the Spirit, the Multiplex Easy Glider has become
my number one recommendation for new glider pilots. Unlike the Spirit the
Easy Glider is made of Elapor foam. It can take a real beating without
requiring a lot of repairs. I have flown one off a hi-start and a winch.
It flew very well. Beginner mistakes that would send the Spirit to the
repair table would not break the Easy Glider, or would only take a few
minutes
to fix with some CA glue.

The Easy Glider is available as a kit for $79, but now they offer it as a receiver
ready package. This is pretty easy! $129

Buy the plane, put in your receiver and flight battery, set up your radio,
balance it and you are ready to fly! in essence, this is your radio with a
RTF plane. I think receiver radio set-ups are going to be a huge hit!

Of course there are lots of other wonderful planes available to help the
new pilot get started. The Gentle Lady is legendary for getting new
pilots into the air. I won't list them all. I focused on the Spirit and the
Easy Glider because the are very good and are packaged in a way that
allows you to very quickly and very easily get into the air. If you love
kits, or want an ARF, these and other planes are readily available.


RADIOS

If you decide to buy a radio, I would recommend at least three channels
for the R/E gliders so you can add spoilers later. They cost as little as
$60 including the servos and receiver needed to complete a kit or ARF.
There are lots of choices in 3 channel sailplanes, often referred to as RES
planes. RES stands for rudder, elevator and spoilers.

The Spirit and the Gentle lady mentioned above are 3 and two channels
respectively. There are competition RES sailplanes that cost over $700,
so this class of sailplanes is not just for beginners.

The Easy Glider requires a 4 channel radio, but if you have the budget, I
would recommend a computer radio with 6 or more channels, to open more
options for the future. These start at around $160 including servos and
receiver. The Futaba 6 EXAS or the 7C, the Hitec Optic 6, the JR 6102
and the Airtonics RD8000 are examples. These are not "true" sailplane
radios, but for $150-$300, including servos and receiver, you have a radio
that has several model memories so you can program several planes. You can
fly a full house sailplane, including ailerons, rudder, elevator and flaps,
and have some computer assisted mixes to help you.

Of course you can spend over $500 to get a good sailplane radio, so budget
will dictate what you get. The message is that you can get started for
very little money and invest when you have the money and when your ambitions
grow.


TRIMMING YOUR NEW PLANE

Even the RTF packages will need some adjustment, balancing and trimming,
so be prepared to do a little trimming and balancing. Read the manual that
comes with your plane

If you can spare $25, I highly recommend this video to help you with your
set-up of your glider.

Performance Tuning for Gliders
http://www.radiocarbonart.com/Pages/perftunemain.html
There is a review of the video here:
http://www.rcgroups.com/links/index.php?id=5010

This is a fantastic video that everyone should get! It is from Radio Carbon
Art, a company that makes RC Soaring videos. I have several of
them and they are all excellent.

All I can say is that this may be the best $25 you could ever spend, if you
enjoy flying gliders. It is so full of valuable information and simple tips
that, having seen it, I ordered my own copy. He talks about how
tuning will impact both thermal duration and slope soaring gliders.

You might think, from the title, that this is about racing or competition,
but it isn't. He takes a common ARF, a Spirit Select 2M, and takes the
plane through a series of steps to get it to fly its best. He tells you how
it flew when first assembled, what he found that could be tuned, and then
does
it.

If you don't have someone to help you set-up your plane, get this video.


LAUNCHING

If you go with a pure glider, you will need some way to launch
your glider. You can get a glider with an electric motor, but I prefer the
pure types which I refer to as sailplanes. You usually launch these with a
hi-start or a winch.

Almost everyone starts with a hi-start because they cost under $100, they
are small, and they easy to transport and store. You can enjoy a lifetime
of lift hunting with a hi-start.

Personally I find hi-start launches a blast. The plane goes up like a jet
launched off of a carrier. When it leaves the end of the launch, it just
floats off the line like a sailboat on the ocean. Or you can "zoom" off the
end and gain even more height.

What is a Hi-Start

Rather than go into detail here, let me refer you to a couple of
article on hi-starts and learning to launch your sailplane.

LEARNING TO THERMAL

A thermal is a column of warm rising air that occurs when one section of the
ground warms faster then other sections. As the air raises it draws in
more air. Think of a very slow moving tornado. Not exactly
correct but close enough for first approximation.

Here is a great video on thermals. I highly recommend it!

The Secrets of Thermal Soaring
http://www.radiocarbonart.com/Pages/...ermalmain.html

Once you have your glider trimmed and you are the master of the
hi-start, you will find thermal hunting both challenging and rewarding.


COMPETITION and the EASTERN SOARING LEAGUE

You may have no interest today in flying in sailplane competitions,
but let me tell you that they are fun! You don't have to be a master
flyer. I flew my first ESL competition after only a few months of soaring.
I entered with a 2 meter wood sailplane. I had such a good time I
was hooked forever and I made some great friends.

When you are ready, the Eastern Soaring League sponsors thermal
duration contests up and down the East coast. Working with local
clubs, we help new flyers get into the fun and comradely of contest
flying. And there is no better way to improve your skills than by working
with more experienced pilots. So when you are ready to get REALLY
GOOD, the Eastern Soaring League will be here to help you advance.


SUMMARY

Sailplanes and gliders are just pure fun to fly. You can start with kits,
ARFs, receiver ready or RTFs as I did. For about $200 you can be
in the air, hunting for thermals and having a great time. No fuel to buy
or clean off. The only battery you need is the ones in your transmitter
and your receiver. Flights can range from 2 minutes to many hours. It
all depends on how good a hunter you are. Every flight is an adventure!



Sailplanes are Wonderful!
