If you can make the plane stop in mid air and go backwards that's called 4D (and requires a variable pitch prop).

What Happy said. Plus any time you are flying (in control of the aircraft) when the wings are stalled is 3D flying.

You need greater than 1:1 thrust to weight ratio and lots of control throw and large control surfaces.

Where can I find a good definition of "Park Flyer"?
What does "Sloper" mean?

A park flyer is a smaller plane usually under 2 pounds, and can be flown in a relatively small park. A sloper is a big glider usually thrown off a big slope, and motorless.

It's a bit broarder than that,
a slope plane is a NON powered plane (glider) that uses wind updraft from a land formation (cliff, buildings, hills) to gain lift, as oposed to a "thermal" plane which is a glider that uses updrafts from metralogical conditions to gain lift.

'generaly' a slope plane will have a geater wing loading than a thermal plane.

then within slope planes there are MANY diferent sorts, you can use a thermal plane, PSS, DS, etc, etc

ok smarty pants. who cares about pss ds thermal metralogical bla bla. let's keep it simple.

I think slope and sloper are also applied to variants of ARFs that don't have power or landing gear. At least, that's how GWS does it. They have several different SKUs (er, variations) of a given plane: RTF, NPS (no power but LG), Slope (NPS minus LG). They might be getting away from the slope variant.

BEC vs UBEC

7. What is a BEC?

BEC stands for Battery Elimination Circuit. This is often a built in feature of the ESC which eliminates the need for a separate battery to power the receiver and servos. The BEC takes power from the main battery pack and reduces it to about 5 volts, and then sends it on to the receiver via the red wire of the ESC receiver plug. A BEC will commonly have a maximum amp rating of 1 to 3 amps, and this is usually stated somewhere on the ESC, or on the ESC instruction sheet.

8. What is a UBEC?

UBEC stands for Universal Battery Elimination Circuit. The UBEC is a small electronic device that is used to power the receivers/servos of a model if the ESC being used does not have a built in BEC, or if the BEC of the ESC is inadequate to power the number of servos being used. The UBEC is connected directly to the main battery pack of an electric model, the same as the ESC. In fact, the power input wires of the UBEC are often spliced into the power input wires of the ESC. The power output wires of the UBEC have a receiver connector on them, and this is usually plugged into any open channel of the receiver. If the ESC being used has a built in BEC, that BEC must be disabled when using a UBEC. To disable the BEC of an ESC, simply disconnect the red wire on the receiver plug of the ESC.
