"Hi Tim
Wow, congratulations! Well done, what an achievement!
Great to know what distances can be covered by a small electric plane.
Best regards
Reto"

"I didn't check this website way too long and just noticed now that this T3 contest is running.
Great entries of David with the flying wing in 221s and Rob with the heli in 281s. Congratulations!

"Looks nice. But is definitely not new:
2010 Transition Robotics won the Cool Idea! award and was featured in Make Magazine with the QuadShot: http://transition-robotics.com/pages/projects
2011 the QuadShot was a successful Kickstarter Project.
2012…"

"@Theo: No doubt, the 200QX is a cool quad. You are comparing two completely different machines. The Bebop is a flying camera including highly developped picture stabilisation, FPV and GPS features. To me a real drone. The 200QX is an aerobatic…"

"Cool concept.
I have been thinking of separating hover and propulsion motors for quite a while. The additional weight and the deteriorated aerodynamics are challenging. How to you intend to minimize drag of the hover props in forward flight?
These…"

"Great idea, excellent design and convincing realisation!
Several years ago these guys developped a quadrocopter for backpacking use:

Your coaxial approach has a perfect form factor. Flight time, maneuverabilty and…"

"Hi guys
I recommend to follow this advice:

Comprehensively explained, well-founded, thoroughly tested in all conditions and hard to…"

"Over two hours is very impressive. I think that confirms that 30 min should be easily achieved, even with 1kg payload and 40km/h forward flight.
My best idea for a vertical precision landing of a fixed wing aircraft is a rope landing. This can be…"

"You are right, there is not much information around concerning performance of multi-rotors in forward flight. I see two reasons for this:
- Most multirotors are used for hover flight. Forward flight is not a typical flight pattern, especially not…"

"A well designed VTOL will fly faster and further than a conventional helicopter. E.g. the Osprey flies about 50% faster and 50% longer therefore about double the distance of a comparable helicopter. But it suffers serious stability problems in hover…"

"I think a steep or ideally vertical approach is valuable for your application. For parcel delivery you will typically land in urban areas with lots of obstacles, not in wide open areas. Therefore I like your idea of the deep stall into the wind. The…"

"When descending in hover mode the wing gets reverse airflow. If the plane wants to correct its flight path to the front, it will pitch to the front, like a quadrocopter does. But the wing will create a force to the rear. Same in the opposite…"

"The Wingcopter should handle wind better having the airframe horizontal when landing. Just point the nose in the wind and you should be fine. I am also interested to learn about their real flight experience.
Another issue to consider is descend…"

"I like your approach "simple is beautiful". Simplicity is the silver bullet to reliability.
In stabilized mode the QuadShot acts exactely same as you describe the VertiKUL. Both having a full feature autopilot on board they both fly even completely…"
