RE: First RC plane
The included TX/RX combo is really only for that plane ( he MAY be able to purchase another RX, but there is no model memory in that TX, nor anything beyond channel reverse )...
I'd advise that he put that plane away, and learn on another, preferably with the help of an instructor. ( No Buddy Box with that one... )
After he's soloed and had an instructor check out & fly the Cessna "trainer" for him, should he even attempt to fly it, and then only in the presence of the instructor. The instructor can get him out of difficulty and save the plane as he acclimates to it.
That's not to say it is a "bad" plane... actually it flies pretty well and looks quite good in the air ( I've flown it for people who've arrived with it in tow... ).
It uses standard sized components and batteries too, which is a plus.
But "Beginner" here as advertized is not a "complete novice" as is the OP.
You can see in the video that the plane scoots around fairly fast, and it doesn't come in as slowly as a real trainer.
