principle of turning???
 

hey guys, just curious and not familiar with the technical things about planes but id like to know how does it turn? is your rc plane has 2 propellers on both sides? how does it turn or even on one propeller in front? thanks in advance. :D

Generally, an airplane's turn starts by banking the wing with the Ailerons.

But now, gravity wants to make the plane slide in the direction of arrow "A".

So "UP" elevator is applied. The makes the plane want to go in the direction of Arrow "B"

The combination of the two makes the plane travel in the direction of Arrow "C"

That's a very simple question, however the answer can be simple or very technical.

Simply stated, to turn (called a bank) you tilt the wings.

Depending on the design of the plane, that is accomplished by moving the ailerons. These are the pair of movable control surfaces attached to the trailing edge of each wing tip. (see the attached picture) They move in opposite directions so when one moves down it forces that wing up, and at the same time the other aileron performs the opposite action. So, to bank the plane to the right you would have the left aileron move down and the right aileron move up.

As I noted, that is the simple explanation but it will give you a place to start.

There are many factors that affect the flight of an airplane - RC and full scale. Since you stated you don't know the technical terms it may be in your best interest to gain some basic understanding from a book or website. One of the best books I have found is called "Stick and Rudder" by Wolfgang Langewiesche. Subtitled "An Explanation of the Art of Flying". You can do a search for it and find it for $15 or less.

There are many websites that will teach you some basics too, but as you will discover, a lot of information will be provided by the folks right here at RCU.

I note that some twin engine electric airplanes turn by running one engine faster than the other. A skidding, unbanked turn perhaps?

Jim, I have an airhogs aerobat (yes I am a grownup child with too many toys) this plane uses the twin pushers. and when the rotation
slows on the inboard wing it does seem to stall that wing and induce a bank, Nowhwere near the bank of a rudder or aileron turn.

They probably turn a lot like rudder only airplanes do. Due to dihedreal or wing sweep, the yaw will cause the plane to bank and if there is no pitch control, the increased airspeed of the resulting shallow dive will cause the trim to give the plane "up elevator". On planes with no elevator control, the airspeed controls pitch. The uptrim needed to cancel out the nose heavy CG only flys level at one air speed aka the plane's "trim speed".

On rudder elevator planes, you can do complete rolls without ailerons, the rudder rolls the plane almost like ailerons do. If you switched the aileron and rudder channel on a typical trainer and didn't tell the beginner flying the plane, about the only thing he might notice is that the plane seems to dive more than usual during a turn. A more experienced flyer would of course notice that the plane skids nose in during the turn rather than nose out. Only using elevator and rudder together results in a coordinated (non skidding) turn.
