some more info on coaxial rotor setups

While a coaxial model is very stable and can be flown indoors even in tight quarters, such a helicopter has limited forward speed, especially outdoors. Most models are fixed-pitch, i.e. the collective pitch of the blades cannot be controlled, plus the cyclic control is only applied to the lower rotor. Compensating for even the slightest breeze causes the model to climb rather than to fly forward even with full application of cyclic.

and fixed rotor pitch in general

Poor wind handling immunity is another limitation with fixed pitch RC helicopters. Most fixed pitch helis have a very hard time when the wind picks up because the rotor speed is so slow compared to collective pitch helicopters. This can result in being lofted up high in the air when even a small gust of wind hits your bird.

We can see by the model below that there is possibly a swashplate controlling the lower rotor, but no pitch control.





TLR the matter is, that this unit will not be very controllable or stable in windy outdoor environments, like on clifftops where you might want to take selfies, tops of mountains, bridges, outdoor areas like the opera house...

so its an inside toy only..
