Hobbyzone(horizon hobby) does use the 72mh radio in some of the parkzone planes like the T-28, typhoon,stryker, and some others. You can use the 72mh stuff in the the hobbyzone planes, but you have to change the rx and the servos. I am in the process of doing this to one of my Super cubs so I can use my futaba radio and buddy box with it. I'll post how it works out when I get it flying.
