Trung Nguyen replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"The antenna you linked to does not specify whether it is SMA or RPSMA connector.  The RFD 900 requires RPSMA.
That antenna is a simple monopole.  It typically needs a ground plane to work properly.  I doubt you will get anywhere near the range you'r…"

Trung Nguyen replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"Does anyone have a link to firmware version 2.4 (mentioned by Ken earlier)?  I've found links to version 2.4 for RFD900+ and RFD900u, but the RFD900x section is grayed out/no links.

Trung Nguyen commented on moglos's blog post Anatomy of a 425km Flight
"Big congrats, Moglos!  A great achievement not only in powertrain optimization, but in support planning.  Almost 8 hours is a long time to keep ground equipment powered.  (unless you have the luxury of flying in your back yard)  Is there a reason yo…"

Trung Nguyen commented on Gisela & Joe Noci's blog post Dipole style antenna for 433MHz
"Hello Joe,

I have seen some dipoles (and yagis) use tubes as elements rather than solid rods.  What advantages or disadvantages are there?  (besides improved rigidity)  Would the same length to diameter rules apply?  Would the tube OD be used for t…"

"Congrats Rob.  Funny I find it cool/novel to watch a heli autonomous flight video.  They definitely don't seem to get much love."

Trung Nguyen commented on Marco Robustini's blog post Endurance tests with "APM:Plane": over 3 hours archived with "Mini Talon"
"Marco, are you referring to your plane's big brother?  It has proven to be one of the (hobby) air frames well suited for long range flight.  I am not sure if it is the best for long duration."

Trung Nguyen commented on Marco Robustini's blog post Endurance tests with "APM:Plane": over 3 hours archived with "Mini Talon"
"Nice job Marco.  My first endurance test a few years back was in windy conditions like that.  For much of the flight, it resembled a kite.  What made you choose 11 m/s?  Is that the min power V for the miniTalon at that weight?"

Trung Nguyen commented on Sam Tabor's blog post Ardusoar cross country X-Plane simulation
"Sam, I know the feeling.  Work was very busy for me as well, but I'll have to find the time.  I only have APM derivatives, but thought the Pixhawk's digital air speed sensor may be of use for thermalling.  I was very impressed with the stability of…"

"Hello Sam, it's almost flying season here.  How did last summer go with your Ardusoar code?  Were you able to get it compiled for Pixhawk?"

"Nice to see your talon flying.  How is the mobius gimbal working?"

Trung Nguyen replied to Edgar Scott's discussion Autonomous Flying Wing in ArduPlane User Group
"If you haven't flown a flying wing, I would suggest getting some stick time on a low cost, highly durable one to start with - then add APM, etc.  An EPP model, such as suggested by Stephen, is very durable.  I might even suggest a smaller one to sta…"

Trung Nguyen commented on Gary Mortimer's blog post US drone registration rules to be announced today (Monday)
"This is a little confusing.  The link to this page is highlighted with "NEW ITEM".  Did they change their minds?

Trung Nguyen commented on Trung Nguyen's blog post Phantom FX-61 Flying Wing 114 km Flight
"A guy at my field flies the FX79.  The fuselage is much bigger (wider).  I am not sure how much more practical room it provides, since I have not build one myself.  If I get a chance, I'll take a closer look next time."

Trung Nguyen commented on Trung Nguyen's blog post Phantom FX-61 Flying Wing 114 km Flight
"Hi Arga.  Like iskess said, it would be pretty tough to squeeze all of that in the FX.  I posted a photo of my internals on page 2.  It was a mess.  With that much battery, you'll have to mount them pretty far rearwards to hit the CG - this is with…"

"Stanley, are you using PWM input or PPM to the APM?  Do you have aileron control?"
