"Could you do me a massive favour, and repeat the test but without the quad motors or booms? Simply the clean airframe with same battery and payload? I would love to see the difference made by the additional drag and weight caused by the VTOL…"

"This is surprisingly good, and pretty thought provoking. I can imagine using it also to plan paths quite intuitivley."

"Wow Martin, that's a great idea! As you just said above, you could fly a real drone with just telemetry and no video feed, that's pretty innovative. It would greatly improve "return to home" operations."

"Could you have a multirotor tethered to a big rover? Fields always seem to have tractor tracks through them, you could drive down those. Rover could have a generator on board to keep flight times high, or just a big bank of cheap batteries. The…"

"Can someone please enlighten me, why did airbus do this? Clearly it was nothing to do with technical design, it was totally to do with social engineering or marketing. What did they gain from this?"

"Something I don't understand - you complain about lightweight components costing a lot of money ... then you go and use 4 legs = 4 times the material cost. And you don't exactly go slimline, it looks like you could stand on that thing without…"

"How does the target lock work? Computer vision? Or calculated from gimbal angle and distance of target from sensor?"

"I'm really pleased you are extracting the QX1's potential. If it can be interfaced nicely with a drone then this cam could become simply the best drone cam available, because it's minimal, cheap(ish) and high quality.

I don't like using wifi on…"

"What I meant was the c.g. changes as the zoom moves the internal lenses around. Since you don't know what I mean, you obviously aren't experiencing this problem which is great for you :]"

"Looks great, lovely project.
Does it stabilise OK when zoomed in/ zoomed out? I'm asking because the centre of gravity changes, which made my gimbal very sad indeed when I tried something similar."

"Aha, this is the best reason I've seen so far for getting an airspeed sensor. Free energy!
Looks good Sam, I'd love to try it but I seriously doubt the thermalling capability of the Phantom flying wing.

On an loosley related note, have you ever…"

"Haha, hi Sam.

I'm not old enough to be wise, but the mandate is true! One must not share technical data via powerpoint!

I chickened out of the airspeed sensor because of the eye-watering cost - £41 !
I will buy the cheaper analogue one, but only…"
