In this episode of Flite Test, watch as the team shows you an amazing aircraft built from scratch! This isn't a plane, and this isn't a helicopter. Its an Avatar Gunship!

Hi guys,

James here from the UK, aka BUZZVIEW. I have just joined your site, but have been following your exploits for some time. Fantastic work from you chaps! Your enthusiasm is infectious and your engineering skills brilliant.

Regarding the Avatar gunship project, I have an idea that might help with the stability issue, specifically when accelerating and decelerating. What might help is having a movable tailplane; i.e. an all moving stabiliser linked to the the forward/aft vector of both main rotors. By that I mean, as the aircraft decelerates with the main motor's combined thrust vector aft of the vertical thrust line, the stabiliser would tilt down, producing fairly high drag and a nose-down pitch moment to counter the induced pitch up moment from the aft thrust vector.

A good example of this is a real Blackhawk helicopter. As the helicopter decelerates you will see that the stabilator automatically deploys in order to counter pitch up, enabling the pilots to continue to have a clear view ahead and below. Conversely, as the aircraft accelerates and transitions from the hover the aircraft will want to pitch down, so the stabiliser will need to move to a 0 degree pitch.

A tricky bit of engineering, but maybe you could interconnect the the stabiliser to the froward/aft main motors servo?

Keep up the amazing work.

Cheers for now,

James
