Hi Mikel...

I too have been looking at these with interest, particularly the way in which you can control the actuation speed and wait time per strut. This is very appealing from a Mustang point of view, as the real ones use separate hydraulic actuators that never seem to be in sync and this will mimick the action nicely. There are plenty of aircraft that this would suit.

The drawbacks seems to be :-

[ul][*] Cost. Now you have to buy the actuators on top of a nice set of retracts that are already pretty expensive.[*] Gear doors. You still need a system to actuate the gear doors. Air is the default but then you have to support both systems in the aircraft - One reason for the Lado's was to eliminate the air system.
[/ul]

Other than that, they look pretty sweet. Primarily because of cost, I am still sitting on the fence and waiting a while. I would be interested in which route you take.

Good luck!
