The q series is are all decent enough to fly and do have some really good points. Touch screen controls and fairly spacious consoles.
I have followed one through from the factory over the past year and to be honest it has had some problems which suprised me however a lot of these may have been increased due to inexperienced operators (even worse than me and I am no superstar).
In general though they are quite good they just seem to be vehicles that need to operated all the time they do not seem to work so well after any amount of time stood in a wharehouse.
They also now come with closed loop control and have vacuum test points on the pods which they never used to have.
SMD seem to have been listening to the offshore feedback and improvements can be seen between the various systems.
