Default RE: RC Universe abbreviations, terms and acronyms list

I was in the glider section and thought to myself it would be nice if there was a listing somewhere of all the abbreviations, terms and acronyms used on RCU. And the same day i came across this thread. The items listed below i found in the glider section and it took a little while to figure them out.

RE or R/E = rudder and elevator only
RES or R/E/S = rudder, elevator and spoilers
REF or R/E/F = rudder, elevator and flaps
RET or R/E/T = rudder, elevator and throttle
Full house = rudder, elevator, ailerons and throttle

Just because I know about it, youmay wish to add this one. Seems to fit with some of the others in your list; not exactly aircraft related, but fits with RTFM.

ID 10 T
code word used by tech support personnel said to another such wizard when they are speaking to someone highly ignorant of the product they are trying to use; they haven't read the manual, they don't understand terms, and they cannot describe their problem in any form of intelligent conversation. Pronounced eye dee ten tee; spelled "idiot"

ORIGINAL: ragris

I still have not seen (1/2 A) defined, unless I missed it. If anyone knows what it means please add it.

Back in the beginning (no kidding), model airplane motors were classed by sizes and the sizes were A, B, C, D.

Someone then decided that .049 displacement engines would start a class and they happened to be one half the size of class A.

taa daa..... you got 1/2 A.

The yellow circle means: new messages

The gray circle means: no new messages

The flashing means: hot topic!


For the faces next to the Edit message windows:

If you right click over one of those, and then select Properties, the name of the animated picture will show.

For example, s14.gif (for smile #14), punching.gif, wink_smile.gif, etc.

Thanks!!!

Regarding the yellow rating stars of any thread, Who rates them?

Do we vote for any specific thread or they are given by the RC Universe staff?

Best regards

"One place where you get lots of acronyms is text messaging. There are lots of that you cannot even keep up with all the acronym meanings, and they keep on changing constantly. Of course the common ones like the TTYL acronym (talk to you later) or LOL (laughing out loud) must be familiar with everyone but it looks like there are new ones every day."

I am suprised nodbody mentioned this yet

RF = Realflight
Then there is all of the g_ version names for realflight... g1, g2, g3, g3.5, ect
BH = Banana Hobby.
Hucking = hanging the plane by its prop, a 3d term
3D = an aggresive style of aerobatic flight, often involves "hucking" the aircraft.
Overpowered = there is no such thing.
"Old Fart" = refering to the senior members in the local rc club.
HK= HobbyKing
__ccer = refering to an aircraft with a __cc engine. EX (example) "I lawn darted my brand new 50ccer"

Hi,

For some reason, I have not received any notification of any activity on this thread until now. I checked and found the list back at post 91 (end of page 4). I hope this helps.

Fly4Fun,

Wayne
