"Why does QuadShot have bad descent characteristics in hover mode?"

"Okay, nice to know! Thanks ;-)Wingcopter is very cool indeed! I like their video where the plane takes off in the forest and flies to an open field. Very maneuverable. I'd like to know how well it handles wind..."

"We were indeed familiar with QuadShot and Atmos. However, QuadShot has ailerons, VertiKUL has not. Atmos has two tilting props, VertiKUL has not. Absence of servos and tilting mechanisms was for us a basic design feature to have higher robustness…"

"Okay, your talking about final descent in hover mode, sorry.
Well although at first I thought this is better, I'm not so sure. Because this is not a stable situation... if the wind turns the wing a bit (quadcopter yaw) it will turn in completely,…"

"The image processing, or automated landing altogether wasn't my part, but I'll ask my collegue about it..I didn't know about the 'red balloon finder' yet, very cool!Thanks for the ideas about dealing with wind! However if you point the wingtip into…"

"And yes, a big downside of this concept is that it doesn't like wind. Especially for hovering and transitioning, because the wing is then perpendicular to the air stream. Indeed, maybe by aligning the wing with the airstream during landing it…"

"Landing was actually a separate thesis. Unfortunately there was no time to integrate it on VertiKUL. Precision landing on the platform you see was achieved with a 450 Flamewheel and indoors. Accuracy was about 5cm, if I remember correctly, based on…"

"It accually weighs 4.8kg with 1kg payload included"

"Good remark, but the reason is simple: a real tailsitter does not allow such a easy parcel insertion as this one (see video). Also a tailsitter normally still has control surfaces. One of our goals was to have a transitioning VTOL that has no…"

"@Daniel: this was a thesis project for Cyriel, Maarten and me. There is still a lot of work and next year new students will continue working on it together with Bart. However commercialization is not at hand, yet ;-)"

"@ Rob: do you mean how stable is it? We've flown only up to angles of attack of 40degrees, so under the still under the stall speed. The reason for this is because its cruise speed is about 70km/h, so to fast to keep track of in our small testing…"
