The helicopters are all obsolete.
the Kalt Enforcer ZR no parts available
The Schluter heli star, maybe a few parts available, that heli hasn't been made for nearly 20 years
The Bell 222 UT , looks like it may have a Schluter heli in it, maybe a Junior 50 or a Scout 60, Schluter did a 222 Fuse and I think it was for the Jr 50.
the two Jr 622 radios are ok they will get someone started on flying helis and planes but that is about all
The JR max 4 is just a 4 channel radio, fine for a trainer plane.
The plane looks ok from the pics.

Total package I would not give more than $300 to $400 for it
