Nowadays, The FM transmitter is very safe, one in the very long while I have seen sone one who uses it. Therefore, the FM transmitter user does not have to worry about the interference as it used to be, after the invention of 2,4 GHz transmitter. This is the four-channel transmitter: Throttle, Aileron, Elevator and Rudder. This transmitter can hold the memories of four models numbered from one to four. You can’t name the model’s name, you should make a label, and stick it on the back of the transmitter, for example. Model 1 : Piper Cub. Model 2 : P-51 Mustang. The trim switches is mechanical ones. You should always keep them at the neutral for all your planes. Move them back to the neutral position after you have trimmed them on the maiden flight(s). The trimming that you have done will be stored in the memory. The process is called: TRIM-MEMORY It is fully explained in the manual. There is one picture for TRIM-MEMORY, you can read to understand. Repeat this process if you have to trim again. This set will be enough for two airplanes. Two receivers and eight servos are used. New receiver switch (you do not need if you setup for the electric plane). If you have a FM receiver with the different channel number. This transmitter can be set up for the V-tail, or delta wing plane. IT IS VERY ECONOMICAL FOR THE NEW STARTER. THANK YOU FOR LOOKING.
