Hi, Karl!
I still don't know what TX you are using! Is it MULTIPLEX (Which one?) or is it Futaba, Spektrum ...?
Above all: there is no difference in all the Easy Gider version concering programming as long as they all use ailerons.
For the EASY Glider (no matter which version) you need to program two servos für aileron (left and right!). There should be a respective wiring inside the Easy Glider - two extending leads to the receiver on two channels. Make sure the little plugs are connected the right diretion to the RX!
If only one wingaileron works try to plug it to the other lead - just to prove the leads are ok. Is the servo in the other wing ok? Try to test that.
Of course, two servos for ailerons need your TX being programmed to it. You have to choose a tempate for that - in most cases "glider" or "sail plane" should do. If your TX does not work with templates it should be possible to assign two servos to aierons. Mind that the servonumbers MULTIPLEX uses might not correspond to the setting of your TX/RX. MULTIPLEX usually has this setting: 1 ail left - 2 elev. - 3 rudder (gear) - 4 gas (motor) - 5 ail right. Futaba, Spektrum or Graupner differ from that!!! I don't know their setting by heart. there you con see why I need to know what kind of TX ist is. Try to post a picture.
