PLL or Phase Locked Loop is the synthesized module, meaning there's dials on the back to select any channel in the band your using, in our case theres 50 72mhz channels to choose from in North America.

Yes you can select ACRO or airplane mode in the interface, the other differences are that the throttle action is smooth, not ratcheted and the switch layout is slightly different. Its fine for airplane flying, thats what I use to fly many planes, in fact, I prefer flying 3D with the smooth throttle, the clicking, to me, is a nusance.


Its a great radio, you'll love it.
