Originalmente inviato da luca.masali  si chiama mode 2 proprio perché è arrivato dopo il mode 1, ed è stato introdotto per vendere nuove radio.
Se hai voglia di approfondire, questa è la storia:
In the olden days, there were no ailerons, just rudder which controlled both yaw and roll. Before Digital Proportional radios, all channels were controlled by push buttons or toggle switches, with one switch for yaw/roll and another for pitch. The controls went "Bang-Bang" from neutral to full travel and back to neutral.
Pitch control was on the left side and yaw/roll control (rudder only) was on the right on the theory that RC flyers could not move one hand fast enough to simultaneously imput pitch and roll/yaw commands, you would have to take your fingers off the elevator switch, and move them to the rudder/aileron switch. Some radios even had three seperate switches or "channels" for each control, push one for up, one for neutral and one for down, and thus a "ten channel" radio would allow you to achieve left/right/neutral, up/down/neutral, and four throttle settings by keying ten differnt switches.
The cheapest two channel radios, mostly for surface models, continue to be set up this way, a "side to side" stick on the right and an "up and down" stick on the left.
When Digital Proportional radios hit the market in the sixties, and gimbal control sticks were introduced, roll/yaw control remained on the right and pitch remained on the left because that is what the most experienced flyers were used to. Gimbal control sticks however also added the function of two controls on a single control switch, so, since roll/yaw was traditionally controlled by the right hand, it stayed there and became the aileron stick, with throttle added. Elevator remained on the left and rudder was added to make for "full house" or "four channel" control. Thus the original control mode was "Mode I".
Later, it occurred to someone that it would be better to emulate full scale airplanes and put the ailerons and elevator on the same stick, and since most people were right handed, the right stick was chosen, and this second control mode, or Mode II was born.
Many competition flyers however, chose to keep the original Mode I set up, and many current competitors do the same. Their theory is that they have more precise control using one hand for roll and the other for pitch. Some of the top flyers thus continue to use Mode I for this reason. |
