Beware if you are in Spain

Posted on April 9, 2014 at 10:34am 23 Comments

With thanks to Patrick of GrupoAcre in Spain for sending this to us.

Yesterday we came to know (by news) that the Spanish Air Safety Agency (AESA) has suspended “All UAV Operations in Spanish Airspace” and further has declared that all operations, which are not conducted on a “Radio-controlled…

Hey there G - Hope your trip went smooth...
Thanks again for all the flying - and donating your airframe to the cause. Been speaking with Stuart a lot more... He's fast!! Quadro-chopper still is not on the table in front of me- but Ill give you a shout when it is- and post some pictures.

not too many repairs to be done to your craft- just changing the wheels really and thinking about molding a new nose for it..

Again I'll post pictures when anything happens..

Till then, enjoy the sunshine I guess.

No problem. I will take you up on the offer then next time I am in SA + I will try to bring my plane out and get some long duration flying in so I will need some pointers on good locations to fly.

Gary, what's the current state of your "Airframe 1 in FlightGear" project? Let me know if I can help you with the aspects concerning UAV Playground.

Am looking at assisting drug enforcement on the Seychelles. We are busy acquiring a Bank License there and need to assist the Island folk with other infrastructure. They have a huge drug problem evolving and their sea is vast and have 115 islands although we would only need to concentrate on those surrounding Mahe. The yachts are the problem donkeys.
What do you think?

Hi Gary

Looks like you had a good turn out for your RCAP event. I have been toying with the idea of arranging an informal event here in Southern California for autopilot users but worry that Patrick would be lurking in the bushes to report us all to the FAA.

Your new airframe looks good. Any plans to make it available for sale?

thanks for your response Gary. I was starting to think I was all alone out here. Please send me an email on with details of your system. you can check out our website for more details about the work we do. We opperate on large estates for the likes of Tongaat huletts and illovo. 12 000 ha is a fairly normal size that we will have to cover in a week to 10 days, so we need a system that can handle a lot of work. Look forward to hearing from you.
kind regards
