Let's speculate on the functions!
I think this model will have 4 multi-directional switches like the 42113. The first function will be motorized rotors, obviously, and this function can be only switched in one direction. The description mentions two winches, so I think they will be the next two functions.
That leaves one motorized function undetermined. I can think of three things that can be motorized:
- Landing wheels. According to the clips on YouTube, this aircraft can fold its wheels slightly
- Rear ramp. I'm not sure if this function exists in the real aircraft, but it would be unusual if it doesn't.
- Cyclic pitch.
I think the cyclic pitch will be motorized so that this set can be an improvement over the previous aircrafts. The other two functions can be manual.
