I saw this a couple years ago thought i'd post once again:

RC Definitions


ANGLE OF ATTACK - Direction from which you are hit after setting up a nice mid-air with your clubmate's new plane.
AUTOROTATION - What your car does on icy roads.
BALSA - What dreams were made of.
BERNOUILLISM- Name of an antique sect regularly discussing religious problems(the weight of air, the speed of air, the 'mystic' reconnection of air)on rec.model.rc.air. Auto generates flames. Often revendicates vote for splitting to alt.religions.sect.Bernouillism.
BLIND NUT - Judge at a pattern contest.
CARPET FIBER - When others are bragging about their high-tech composite planes and you have only the Gentle Lady you built on the floor of your two-room apartment, mutter quickly (under your breath), "YEP, THIS BABY'S REINFORCED WITH carpet FIBER!"
CIRCLE TOW - How to point someone in the direction of the scoring tent when you have both hands holding your plane together until the quick epoxy sets.
CRASH - Quick method of removing radio and engine from a model to fit them in your new one.
CENTER OF GRAVITY - Point in which G-forces,dedicated to separating wing from fuselage, do their stuff.
COMPUTER - Device that enables you to make mistakes at the speed of light.
CYANOACRYLATE - Special glue, designed to instantly glue fingers to balsa structures.
CYANOACRYLATE - Also : Special glue, instantly curing when parts are misaligned, will hardly (if at all) cure when parts are correctly aligned.
CYANOACRYLATE - Also : Substance used to make eyes water profusely at critical points in construction.
CYANOACRYLATE - Also : Stuff usually dripping on your clothes, turning them into armor and you into a modeler knight.
DEAD STICK - Two of these can be found on your transmitter after failing to properly charge your batteries.
DEAD STICK - Also : The Yucca your aunt gave you to clear the air in your shop after 3 months lack of water.
DOWNWIND TURN - Sensitive item that, when posted in REC.MODELS.RC.AIR, will generate threads of 100 entry's and up.
ENGINE - Device designed to make noise. Will suddenly stop making this noise when beyond glide-in distance.
EPOXY - The stuff that has replaced the balsa after the flying season.
FAIL SAFE - Option on PCM radio's that allows a pilot to choose whether to crash near him, or a long way away.
FIREWALL - Removable part of fuselage. Comes off on landing.
FLARE - What someone has when they're good enough to show off.
FLARE - Also: Beginner's luck.
FLYING WING - To be seen after too tight a loop.
FUEL TANK - Plastic bottle, designed to leak when placed in totally inaccessible locations.
FUSELAGE - Optional interconnecting structure between wings and engine.
FUSELAGE - Also: Receptacle into which the R/C pilot stuffs money in the hope that his plane will fly better.
GLITCH - What you holler when you pull up elevator while flying inverted at 10ft altitude.
GRAVITY - Force of nature designed to reduce aircraft to their component parts.
LANDING GEAR - Structure to separate fuselage from runway after landing. Does not always succeed in doing so.
LANDING - Comes in multiple forms
GOOD - The plane comes in contact with the ground, and all bits are still there. (rare form)
AVERAGE - The plane comes in contact with the ground, and most bits are still there. (most common form)
BAD - The plane comes in contact with the ground, and all bits have grown in number but diminished in size. (common form)
LUCK - Comes in multiple forms:
PLAIN Very sparse on your side, but plenty with your flying buddies only they refer to it as SKILL.
TOUGH This is what you usually have. Your flying buddies refer to it as lack of skill.
BAD Same as TOUGH.
GOOD What you need the most.
MEAN AIR CHORD - That nasty minor eighth note caused when your wings snap on launch and whack together.
MIXTURE SCREW - Device to meter too little fuel to engine at critical moments.
NOSEWHEEL - Implement used to remove firewall.
O.S. - Initials of the two words that an r/c pilot says when he loses control going straight down.
PROPELLER - Rotating knife that cuts holes in the air, which the aircraft falls into, thus propelling the aircraft.
PROPELLER - Also : Handy tool to cut away excess skin on knuckles.
PROP NUT - What Glider pilots call Power pilots.
P-51 MUSTANG - What beginners use to learn to fly.
RADIO- Expensive electronic device to randomly alleviate overcharged batteries.
RADIO GLITCH- Documented Electronic occurance, causing immediate and irrepairable loss of control.
RADIO GLITCH- Also : The source of any crash when there is a possibility of someone else's radio in close proximity to the plane.
SWEPT AREA - The only part of your apartment not covered in balsa dust.
WETTED AREA - After Rex the Wonderdog finds the swept area.
TAIL-DRAGGER - R/C pilot who has spent an hour looking for his plane in a forest. See also glitch.
THERMAL - Mythical occurance of rising air usually where one's sailplane is not.
TRAINER CORD - Handy device for electronically instilling false confidence in rookie pilots.
TREE - Implement used to separate Wings from Fuselage. See also "glitch".
SINK - Non-mythical meterological event stimulated by rc soaring contests.
SNAP ROLL - After a nice hard G roll, something SNAPS(usually the wing).Aerodynamic ability will slightly diminish.
STALL - Score Gravity: 1 , Mr. Bernoulli: 0 .
TIP STALL - Offering several minutes worth of unrequested advice to a nearby pilot instead of taking your turn to launch off the winch; used when sink is
in the air and contest points are at stake. See 'sandbagging'.
UPWIND TURN - Same as DOWNWIND TURN. . . . NO it isn't ! YES it is ! NO it isn't ! YES it is ! NO it isn't ! YES it is ! IS NOT ! IS TOO ! IS NOT ! IS TOO ! IS..... etc. etc. etc.
WING - Device that, due to it's airfoil, allows air to flow faster over the top, thereby allowing you the opportunity to pour excess funding into the resulting low-pressure area.
WING AREA - What you get more of in the car by leaving the wife at home.

those are great.

here is some general aviation ones.
