Amazing models that look very scale like, and yet clearly no attempt to
make to scale some of the details you'd see when it's on ground. The
propeller mast and it's doors, and the landing gear are what I noticed.

Most (not all) of these RC planes large enough to launch a dog/small
child in use prefab generic (mechanically proven) self launch hardware/
installations... along with generic retract wheels, operational
release hooks, airbrakes etc. Evan as such, these models are fairly
expensive, but with authentic scale hardware would start rivaling
costs of the real deal.
