I am new to flying and trying to change altitude. I just received my HK VENTUS 2.3M EPO Glider and I woulkd like to know how to utilise all the channel Program Mixes that my stock HK TGY9X Radio can give me. I have tried searching on you tube and other forums but I unfortunately have been unable to get answers. I would like to achieve something similar to what was being shown on the Ventus flight review by Josh and David of flite test.

Thanks in advance to anyone who can help.
