VGs- Example of VG to allow root to stall first, to prevent wing drop at low speed, could be tried in a RC model

VG are pretty common for chuck catapult gliders, if any one remembers building the Yellow Bird (kitted by Aurora in India) it has a thread leading edge which is a Vortex Generators. I had a fair size chuck glider built ( Proteus designed by John Buskell) from plans where the wing had a 90 degree drop of about 1/16 from HPCL. This was a prime example of VG's

there is a confusion regarding the Word 'Sortie', in fact this word came into proliferation in a Cavalry Attack,One Cavalry Charge was called a Sortie, (read 'The Far Pavilions'). this word means

1. An armed attack, especially one made from a place surrounded by enemy forces.
2. A flight of a combat aircraft on a mission.

The term has been adopted from the French word  "sortir", meaning "to leave" or "to go out" with a specific purpose.

In the English-speaking world "Exit" is used to denote the way out of a public place; in the French-speaking world it is "Sortie". (see image)

Disclaimer
A lot of people even today call it, 'sotri', this post is to clarify the same

Going thru various sites I get to see terms like v-tail, tailerons, elevon, stabilators etc. Are these different controls or is it different name for same type of control wherein two halves of elevator is mixed to function as either an elevator or aileron?

High spirits we have: gravity we flout.



Stabilator = complete horizontal stabilizer works as elevator (all flying tail).
Tailerons = elevator (generally a stabilator) split in half and each half can mover differentially to perform roll like ailerons do.
Elevon = Type of control generally used in flying wings and v-tail. In this configuration the same controll surfaces are used as elevator and aileron.

SLS,
Huh? still confused..
Elevon - is similar to elevator + ailerons  - right? Seems to be the same as tailerons as per the explanation. So what is the difference?

Stabilator - rudder working as elevator Huh? How is that possible ?

Any diagram or picture to help understand? Till then  Bang Head

The only difference is, elevon is on the wing and taileron is on the tail.

No, I said complete horizontal stabilizer working as elevator instead of just a part of it.
 
Also do read these wikis
http://en.wikipedia.org/wiki/Stabilator (this article also includes taileron )
http://en.wikipedia.org/wiki/Elevon

Feel free to ask if you still have any doubts Thumbs Up

Thanks SLS..

BTW, not sure how the reputation thing works. I thought of giving you a + for explanation, but somehow even after I added a rep, the count remains the same

If you get mixed up between Port and Starboard, here is an easy way to remember - Port and Left both have 4 letters.

In fact there is an interesting story about the origin of the word POSH (high class). In the good old days when sea travellers journeyed to the United States from the Continent, the rich would book Port side cabins on the outward journey to safeguard themselves from the icy winds that blew over the Antarctic and came in from the North. On the return leg while journeying back home, they would book Starboard side cabins. All this cost money and could only be afforded by the rich and thus the term POSH originated - Port Outbound Starboard Homebound!

A convoluted way to remember which side is port:

Port means port wine. Port wine is red. Red is the communist party. That's left

@VC - POSH was good trivia

I also now understand that there is a reason behind having a red light on the port side and a green on the starboard side...

http://en.wikipedia.org/wiki/Port_and_starboard

so is the same scheme applicable to airplanes? I see a number of people doing it the other way round on airplanes. Putting green lights on the left wing and red on the right wing for night flying. I am hoping someone from the community can help reason that.

It should always be Red on the Port / Left side and Green on the Starboard / Right side. Same as Maritime vessels.

@sushil_anand - Sorry sire, but I could not understand passing is always port to port. What is "passing" here? and is this only applicable when a vessel is approaching port? Request for help in understanding

Hello everyone
I found it tough for me to find all the meanings off these esc's, lipos, brushless, brushed, tx, rx etc.
But now after reading many beginners guides I know some of the meanings of some rc related stuff.
but I found it difficult in the beginning to do this so for those who are starting in this hobby (like me Wink ) I am taking the iniciative of starting one RC dictionary of RCIndia.
Here it goes

ESC - Electronic speed controller. It is a device which is used to control the speed of the motor.

LiPo - Lythium Polymer batteries. It's one of the most popular batteries used in the RC world.

Brushless motor - Brushless DC Motor does not operate using brushes. Only the outer cans of this motors spins. These are way more efficient and powerfull than brushed motors.

Brushed Motor - Brushed motors are less powerfull and efficient than brushless motors but they are very cheap.

Tx,Rx - Transmitter, Receiver. It is an device which transmitts signals and the receiver receives them they are binded using an bind plug. They react upon our stick movements.

Servos - These are devices which control your control surface like rudder, aileron, elevator, etc.

Experts please correct me if I am wrong and can add more things if they want or know

Indeed. Good initiative Nitesh. However, please make an effort yourself to get the definitions perfect, rather than depending on others to edit them, or the whole purpose will be defeated

Control Surfaces:

Throttle- In electric planes a electronic speed controller is used to to control the speed of the motor hence the plane.
             In fuel planes a servo motor is used to control the speed of the engine. It is connected via a push rod to the throttle hing.

Ailerons- It is a pair of movable surface(left and right opp. to each other) located at the outer edge of the wing. When used it cause               
             the plane to roll to its left or right. 
             Right role is caused when left aileron is down and right aileron is up.
             Left role is caused when left aileron is up and right aileron is down.

Elevators- These moving surface is hinged to the outer edge of the horizontal stabilizer. It controls the pitch of the plane.
               When we give up elevator, the plane nose rises/climbs.
               When we give down elevator, the plane nose drops/dives.

Rudder- Rudder is hinged to the outer edge of vertical stabilizer. It controls the Yaw of the plane.
            Left rudder cause left yaw.
            right rudder cause right yaw.

Flaps- These are located at the outer edge of the wing on each side b/w ailerons and fuselage.
          Flaps are lowered when landing.
