We use quite a lot of jargon in this hobby - TLA's and the like - and I've noticed a few posts in the past where forumites have asked what something means or for a more technical definition to aid their understanding.
 
I've found myself that, even when I vaguely know what a peice of kit does, I still can't find out what the acronym stands for despite searching on google. As an example, I had no idea what a UBEC was when I came to model flying, and I didn't know what ROG meant when I first heard it mentioned either!

Maybe a little obscure but diesel as in diesel engines and all other things compression e.g. 
ether
IPN = Iso propyl Nitrate 
Amyl Nitrate
contra piston

The glossary is starting to look very impressive - well done David for all the hard work behind the scenes on this one.

 Not obscure at all, Tim
 
Diesel, and Compression Screw, should definitely be in
 
Another couple of generic i.c. related terms that coud be included are Mixture, and Idle
 
Fully agree with Allan and BeB - very impressive work!

I ask folks for their definitions as I don't really have the time to chase around seeking such so if you can do a google search or something then that's really appreciated.

I thought it a great sign of the times that the diesel engine definitions were not included straight off!  Its an interesting thing to compare the glossary from age with the similar thing from another!
 
Done thanks David

Couple of errata in DP1's post add 12:44:
 
under "Compression bar" the second "reduced" in the final sentence should read "increased"
 
Should we add after the definition of "Flick" the statement "This method of starting using unprotected fingers is not recommended" or words to that effect?

Thanks BEB!
 
Ref the advice about flicking, we are not here to assess risk is my feeling.  Further, flicking with a rubber thing on is not easy at all.  its just hard to get a "feel" for the engine without bare hands.

Just a few more - I guess we are nearly getting there with this:
 
Power Panel - a small instrument panel usually mounted on the side of a flight box (q.v.) which contains useful facilities such as; a fuel pump, power outlets for an electric starter and glow plug etc.
 
Servo-Slower - a device which is usually located between the receiver and one or more servos which causes the servos to move to their new command position in a much slower manner than normal. Often used for scale effect on undercarriage retract servos and on flap servos to make re-trimming with flaps deployed easier. 
 
SMART - useful mnemonic to help pre-flight checks - should be carried out immediately before lining up for take-off. The items are:
 
S - Switched on transmitter .
M - Meter showing good tranny voltage, correct Model selected.
A - Aerial fully extended (35MHz), or aerial aligned correctly (2.4 MHz).
R - Rates selected correctly. Range check was OK.
T - Trims set correctly.

Point taken on safety David - and fine for the "old hands" but I'm just thinking that this is mainly aimed at beginners?

BEB, fair point.
 
We cannot however recommend against bare handed flicking when flicking with a rubber thing on is worse because it (a) causes loss of feel and efficacy and (b) makes one clumsy and MORE likely to drop the running model. HOWEVER, we might add something like "flicking , like many things in modelling, is a skill that is often more difficult than it seems and is fraut with risk.  Obvious risks include being hit with a running propeller whilst less obvious risk included severe cutting of the fingers along a sharp prop blade if a hydraulic lock is encountered.  It is recommnded that a modeller wishing to flick a prop for the first time seeks guidance from an experienced operator (preferrably one with ten fingers)"

Control check: The last thing a pilot should do before take off.  Stand behind the plane and move all the controls, one at a time, to ensure that ALL the operated surfaces move as designed and in the correct sense.  Rudder stick left / right, rudder left / right. Elevator stick up / down, TE of elevator up / down. Aileron stick left , left aileron up , right aileron down. Aileron stick right, left aileron down, right aileron up.  Blip the throttle -  forward stick faster. Flaps, equal movement.  NB just waggling the sticks to see some movement is a useless activity and does NOT comprise a control check.

Another erratum in my own post on Diesel engines. I mentioned Otto cycle engines in the same breath...it aint necessarily so, as they say. Best delete ref to Uncle Otto.

Just a small correction (and a pet thing of mine) The A in SMART is Antenna, not Aerial, an Aerial only Recieves, not transmits....

Nah! Antenna is american Aerial is British - they both do the same thing - it's just that they have a problem getting the e in the right place
