i have a falcon 8 since early 2011, and at first look... yes its pricey.
but when you have one, and do some work with it, you will find that it is not as pricey as you may think.
It's incredibly stable. as a mater of fact, it seems like the more wind, more stable.
once i have to fly with 40 to 65 km/h gusty winds... and the falcon handle it
then is very easy to transport, i have some works that i have to go on a motorcycle between locations and there is no problem.
it's truly a "one man show" you can do the flying and the camera adjusts... its very easy. but if you want it could be a 2 man job... it's up to you
you "feel" that is a pro system and you feel relax that you don´t have to worry with the falcon 8. your mind is only on were you want to go, and how you want your camera.
it has a fantastic feature. you have like a co-pilot telling you if there is a problem with the gps signal, the battery level, if the wind is too strong, if you have a motor fail... and so on
and it has some other features that after 2 years i haven't see in other rigs. and if you think that is the same model... it´s not. in this 2 years there have been major changes
then the people at ascending are super. once i had a problem with the black box sim card, and the falcon do not fly if there is a problem. i was on a very important work, i send a email to asctec and 15 minutes after i have the solution. you feel that they are there for you, and they don´t want you to fail also.
as it was already said, is not a multirotor for heavy Red Epic, FS-100 or canon 5D. but for most of the work you don´t need those kind of cameras. and with the falcon you can change between cameras in 30s
And now the cameras are getting smaller and better. the nex 5 or 7 and the PJ780 camcorder are now the standard and they are great cameras for almost every work.
And as it as already been said, the falcon fully operating with battery, and camera weights between 1.8kg with the nex 5 camera and 2.2 kg with the PJ78VE. i only see rigs to handle with that weight with at least twice the weight
at the end, i love my falcon. it´s very easy to use, very safe, you have firmware and software upgrade and i think that is better multicopter in is class.
you have to pay a price for all of that... but as soon as i could, i´m going to get a second falcon 8. that´s how much i like it.
