- : After absorbing all the above information I still have some questions:
- :
- : - Radio: If somebody *WANTS* to stay with polyhedral gliders do you
- : still suggest to buy a 4 channel system, or a simple 2 channel AM
- : system is enough?
-
- I have Futaba Conquest FM 4-channel radios. I love 'em, but you must
- realize that there is _always somebody_ on the net who has a contrary
- opinion. Buy a radio. It will be okay. Or not. That's the way life
- is.
-
- : - Kit: Can I use STANDARD SERVO-s in the 2 meter planes???
-
- Lots of 2-meter planes can use standard servos (like Futaba S148's).
-
- : Wing loading is a key factor? Lower wing loading stays up longer?
-
- Don't worry about it. Lots of _really_ high performance sailplanes,
- besides being expensive, are relatively heavy. Ideally, you want an
- airplane that will fly slow, fly fast, and turn well. My old Olympic II
- _will not_ fly fast, unless you don't mind shedding wingtips. On the
- other hand, flying slow with more sophisticated airplanes requires
- spoilers or flaps and therefore more radio channels.
-
- : - Hi-Start: There is very little talk about hi-starts in the FAQ file.
- : Any instructions on how to use them? Which one to buy? 300 feet or
- : 800 feet versions? Can I operate it alone?
-
- Find someone else who flies. Ask for help. Use their hi-start. Short
- ones are great for practicing landings. Bigger airplanes need more
- oomph. Once you've launched a few times you'll have no trouble doing it
- by yourself.
-
- : - Covering: Kits listed in the FAQ file do not contain any covering.
- : What can I use to cover them? Monokote (and alike) is/are the only
- : solution? Can I use Japanese paper with tightening lacquer?
-
- Monokote comes in a lot of colors and isn't hard to use. I recently
- tried Oracover and was impressed. Nobody uses silkspan and dope any
- more. ;)
-
- : Do I need the heat gun, or the sealing iron is enough?
-
- A heat gun is cheap and makes the job a lot easier. Seal the edges with
- the iron and shrink the stuff between the ribs with the gun (on built-up wings).
- You can get by with just the iron on sheeted surfaces.
-
- : - Misc: Besides kit, radio, hi-start, covering, iron, epoxy; what else
- : do I need to get started? FAQ mentions '$60 for a 2 meter glider and
- : other supplies'. What are those other supplies?
-
- A good knife or two with lots of spare blades, a small razor saw, a plane
- (I greatly prefer my Master Airscrew over the X-acto), and a sanding block
- are just about bare minimum. Several different sanding blocks with different
- grits are very nice (180 grit on one will almost substitute for the plane).
- I have an aluminum T-bar block 12" long that I really like. It's easy to make
- your own by glueing sandpaper to something. It's nice to have lots of
- different shapes and sizes. Oh, and several metal straightedges in
- different lengths can make your life a whole lot easier. A triangle or
- two for making things square. A couple of packages of clothespins to
- use as clamps. A few small C-clamps when you need more pressure. A
- roll of waxed paper. Scissors. You'll collect things as you go along.
-
- Have fun!
