Hmm you have 2 switchs and one knob on the left side. I think you mean the two toggle switchs.
One switch is marked unless you have a HH gyro it doesnt do anything. If you have a Head Holding gyro it is in normal or rate mode when its in the down postion and in Head Hold when in the UP postion.
The other switch is for Idle up. Unless you are ready to fly stunt leave it in the down postion. When it is in the UP position it sets your left stick so that it is at full power, full pitch when the stick is full forward and full power NEGATIVE pitch when at the back or down postition (used when flying inverted for example). To cut the power and no pitch is right in the middle. This is in the manual but not discribed, good to ask BEFORE you flip that switch in flight[X(].
You also have a switch on the right side marked TRN its for training, NOT anything to do with a simulator as someone suggested on another thread.
A cable is hooked up between your radio and a another just like it designated the "Trainer" He lets you fly by holding his switch in the up position (notice its spring loaded) IF you get in trouble he can take over by simply releasing the switch which will remove control from your radio and transfer it to his.
Oh btw the forum would not let me post that attachment in MS word so I had to use notebook. If you copy it and paste it to your word processor program it will ok and not have the mile long sentances.
