Is it better to draw more or less amps? Or do they both have trade offs?

The way I see it:
draw more amps: more power, bad for battery
draw less amps: less power, better for battery

Packaging Terms

RTF = Ready to Fly

In most cases this means that everything you need to fly the plane is included. The model is built, electronics and motor are installed and a radio is provided. If it is an electric plane this will usually include a fligt battery and battery charger too. RTFs are usually, but not always aimed at the first or second plane buyer. RTFs may require 15 minutes to 2 hours to prepare for flight along with the charging of a battery. Wet fuel RTFs typically do not include the fuel.

RR = Receiver Ready

Typically means the plane is built, and the servos and control rods are installed. In the case of electrics this usually means the motor is installed and an electronic speed control is installed. This may or may not include a battery and definately does not include a radio. You add your receiver and use your radio, charger, etc to fly the plane. Typically less then 3 hours is needed to get these planes flying. Some major subassembly, like the tail, may have to be bolted or glued on, in order to make it easier to pack and ship the model.

ARF - Almost ready to fly

Usually this means the plane is built and ready to receive the electroncis. If it is a wood plane, any covering needed has been applied. ARFs may require 1-10 hours of assembly to get them ready for flight, including the installation of the electroncis, motor, and related parts. In small electric models, the motor is often included and already mounted.

ARC - Almost ready to Cover

Typically this is a wood model that has been buillt but not yet had the covering applied. Coverings such as Monokote, Ultracote, Silkspan, etc. need to be applied. At that point it is like an ARF. In some cases some final sanding might be needed or some major parts may have to be joined. For example the h-stab may need to be glued on because it would be too hard to ship with it on.

KIT - a collection of pieces

This can have a wide range of meaning but typically means you will be doing more than a little joining, gluing, drilling, cutting, sanding or whatever. In a wood kit, this may be a box of sticks. Usually there will be flat sheets that have parts cut but which have to be "punched out" of the sheets. In the case of foam kits, the parts may be major molded pieces that have to be joined.

In some kits, major pieces may already but built, such as a molded wing, but other parts may have to be cut or joined in order to build the plane.

The modeler may have to supply additional parts, such as control horns, metal rods, coverings or other accesoy pieces, in order to complete the build. Then you add your motor, if there is one, and electronics. To get a kit ready to fly can take tens to hundreds of hours depending on the size and complexity of the build. However 30-60 hours would be typical.

Laser Cut - This usually applies to wood kits and refers to the manner in which wood parts are formed out of flat sheets. A laser is used to burn through flat sheets of balsa or ply wood to form parts.

Die Cut - This is an older process where by a cutting blade formed in the shape of the part is stamped onto the flat sheets to cut the parts. This is an older but effective process, however over time the dies become dull and the crispness of the cut can suffer. How clean teh cuts are can vary leading to more sanding and fitting than is typical of the laser cut kits.

Hope this helps.

KV is a rating of electric motors. Means Thousands ( K ) of revs per volt applied.

If you have a 600 KV motor and you apply 8 volts to it you will get 4800 RPMs unloaded, out of the motor. Add a prop and that will drop, I believe.

You know I had no problems figuring out the abbrevaitons, as a beginner. The problems were with the non-airplane terms like LOL.
Still don't quite get that "bump" crap, where the entire post is just that single word.

"Bump" means the person is forcing the thread back up to the top of the forum.

You will notice that whenever someone posts to a thread, that thread then becomes listed at the top of the forum. If you "bump" the thread, this means you are forcing the thread to be listed at the top of the forum. This is one way to keep the thread at the top of the forum where more people will likely see it, and possible respond to the thread. People usually "bump" threads in an attempt to elicit a response from other people in the forum.

Bumping only works for threads that are not "stickys". "Sticky" threads are always listed at the top of the forum, like this thread (Beginner's dictionary).

What does "pylon" mean in reference to the plane. Here's the link ...

also "incidence" when refering to the wing. I'm guess the angle of the wing in reference to horizontal center of the fuse?
