"We are using a Rover Base for the accuracy RTK GPS, but the system is not always easy. Although the system now has accurate positioning, the way points accuracy is an issue. The radius cannot be set below one meter (although somehow I got it work to…"
"Dear Yan,
interesting experiment and seems to work. your approach is interesting too. Can we have a conversation soon. Consider this also useful for our project. Also based on reversed use systems. Best Winfriedrijssenbeek@gmail.com "

Dear All,we are working on a serious project and aim to have triple redundancy in the control; one of the ways of doing this is purchasing a high end system. Our imagination is however whether it would be possible to use eg 4 pixhawks that can be…
"Nice things on your blog!
Yes we got the comments, but that is OK. if you have no experience, you might worry. Think your little 4 prop plane is interesting!"

"We have done all studies and tests before we did the craft. Indeed it performs as anticipated. We have ca 6.7 kWh of battery capacity to lift it 10 min. We need a range extender: now there are many options: ideal would be fuelcel, but not sufficient…"
"Flight time with batteries in 12 motors config is estmated at 10 min, if we choose lower disk loading it can be 15 to 17 min. So definitively need a range extender. We are working on it!"
"It can be both depending on the function. We have a series of applications in mind. A sports version is only one and will take time.. Best Wnfried"
We succeeded 2015/06/25 with a test flight (craft strapped with 4 ropes) with a 80 kg payload. It only used 8 of the 12 rotors! Next,we want to give you a glimpse on how it will look in future (part with canopy) Hope you enjoy. And for all the…
"Sorry height?"
"Dear Greg that is correct to a certain limit, what would be the minimal rescue hight?

"Dear Tony, great to hear from you. We will follow that path FAA 14 CFR part 27 and do the PFHA. This will be in the step after proof of concept. We feel that you might have interesting skills and knowledge. If such craft would be fully airworthy and…"
"dear Bart currently as designed:
Specs: payload 80 kg,
Dimensions LxM 3 by 4 m but 2.2 by 4 if folded. H 1.5 m
Flight time 10 min batteries, one hour with range extender, expected speed estimated 25 to 30 km/hr.
Full weight 150 to 160 kg
After…"

"Dear Tony, EASA you are correct, FAA we doubt. We think that it can be within FAA regulations. The market is 2 fold: piloted one , and RPAS for different applications like agriculture, surveillance, ambulance, military, we are in discussion with…"
"Dear Frederic, the advantage is that it is more compact 3 by 4 m, more easy to control and handle and lower cost if electric storage becomes better. Completely programmable. Indeed propulsion efficiency is lower as compared to a single rotor, and…"
"Not yet, we had conversations with them in an early stage. We aim to have redundancy by 1) 12 separate power and propulsion systems 2) next to have 3 independent control systems (as with commercial aircraft; there are professional systems we want…"
"It is in the structure or in the rectangular section to reduce weight of cables and reduce losses. The Hybrid version will contain a 35 kW generator set."
