"All the drones pictured are fixed-wing.  They probably look like a competitor.  Any rotory-wing craft attacks documented?  I could see perhaps a multi-rotor attack, but what about a large heli?  During the 15 years or so I flew larger helis (600 -…"

""The three-judge panel said that safety was obviously important and making hobbyists register "may well help further that goal to some degree ..."So registering - and paying $5 makes things safer? That's a child-like idea.  What the FAA was…"

"Remember the receiver module can't do anything without an antenna.  For quality dynamic positioning the antenna is going to be much bigger than this receiver module so you don't really reduce size and weight much for a typical drone application.
Now…"

"Basically these results are achievable with any RTK system.  I took a look at a 90 minute session between two Ublox M8T receivers - different model Tallysman antennas, 1 meter baseline, ideal receiving conditions, kinematic RTKLIB processing, but…"

"Anyone who has been into sUAS for a while knows of UNAV.  They were always the low cost leader - and all that goes along with it.  To describe the guy as grumpy seems apt.  Maybe curmudgeon would be better.  Since I was into rotary-wing I never…"

"What you linked there is just basic outline material.  Nothing substantive at all.  Nothing from the FAA.  There was supposed to have been a "comprehensive risk analysis" done.  At least they could share it with us.OK, the FAA actually doesn't do…"

"@Tony Kenward
None of my college degrees say aerospace engineer.
Do you have a point?"

""March 29- After a comprehensive risk analysis, the Federal Aviation Administration (FAA) has raised the unmanned aircraft (UAS) “blanket” altitude authorization for Section 333 exemption holders and government aircraft operators to 400 feet."…"

"The first thing I thought of on seeing this is some pics I have of manned helis carrying these type of sensors.  They are on an older PC which I don't have assess to right now.  But, this is pretty much an ideal use of a gas RC heli as vibrations on…"

"@GuyJust out of curiosity where did you get the 84kg weight for the Shadow?  Reports I've seen say it was 170kg.  Just a math mistake or was there a version that light?I don't think anything about this incident really transfers to civilian flight of…"

"Really?  The August 15, 2011 collision in Afghanistan?  A military operation where the small craft weighted more than 150 kg?  That's applicable to civilians flying < 2 kg craft?  Imagine the damage if it was a DJI Phantom?  Then the C130 would have…"

"Model aircraft have been around for a very long time.  Guess where they were typically flown in the past and still are to an extent today?  At the local airport.  The number of airports where this was done in the US alone definitely goes into the…"

"These studies certainly aren't worthless.  While they may be "back-of-the-napkin" approximations they are down right rigorous compared to anything the US FAA has ever done.The idea that small drones flown in ways similar to traditional model…"

"You can always find people to tell you what is more dangerous.  It's the type of aircraft or power source they are least familiar with.  There's some truth to that because it is for them.  It doesn't always hold for others though.  Sure you can come…"

"Wow, a flashback to the 1990s.  Gas helis were pretty much the only rotary-wing choice then.Heli autopilots have always had pass-through modes.  It's almost a must for someone who flies helis manually as they need to be able to revert quickly to a…"
