"This is a flight I did a few years back at 60 Km/h airspeed.
If you dig back a number of posts, you will find my parameters.
I don't have them on this computer, I've sort of stopped flying :-(
I always wanted to try the autotune for aircraft, never…"
""First, I noticed that in qgroundcontrol when setting up my pixhawk, there is no profile for the talon's v-tail design"
And that is why I suggest you move over to Mission Planner :-) Spetrum DX 8 is quite adequate for controlling a Talon. ."
"Hi Forrest,
Do you think that maybe the main processor is just ignoring the data stream from the ppm encoder ?
My quad since about a year ago intermittently didn't want to arm, but in the field, and I didn't have a laptop to monitor.
Back at home,…"
"Mmm, I also had an RC not respond, fortunately on the ground, on APM 2.6.
Turns out the PPM encoder intermittently goes funny, and does not pass through RC commands.
Fortunately mine happened on the ground, and manifested itself as unable to arm.
I…"
"Unless you have audio feedback, it ain't gonna work.
Or might.
Until things goes south, then there isn't time to look at dots, AND the plane.
Get one of the Hobby King type mode changers, you won't regret...."
"Although I've done zero flying myself lately, I've had to assist a friend with his Talon.
I attach my revised document, and original param file.
Hope it helps......

"If I may, I'm going to expand on post a year or so ago :-)
GPS signals reach the earth surface at extremely low levels, in fact so low that they are under the average rf noise level.
Clever mathmatical trickery allows your receiver to extract valid…"
"Well, then you are already doing better than me.........Almost :-)
I can probably do that with 15000mAh 3S, old 3548 900 Kv motor, two GoPro's, 12x8 prop, and it launches easily in no wind......
What speed are you flying at?
With 23000mAh you should…"
"Yeah, that is my call, on a 3S pack you will be drawing 7 to 9 Amps @ 60 Km/h airspeed.
Not too sure what you have in the nose, I had to put 3x 4000 or 5000 mA/h 3S packs to get the CG right.
Most of my build pictures are here somewhere on the…"
"Hi Hugues,
I'm no expert on electric motors, and I don't like eCalc either :-)
As I posted earlier, my setup works for me, but then, I only fly with two GoPro's
I use Turnigy motors and 3S packs, that way all 12V cameras and other electronics etc.…"
"Hi Michael,
My Talon with wing extensions has a 3548 900 KV Turnigy motor, 12x8 prop, 12000mAH 3S battery pack, and even no wind hand launch I do standing still.
I have a APM 2x in it, launch in manual mode, with full up elevator trim.
I found that…"
"Hi, you have made a fundamental "Basic" mistake.
"Loiter_Unlimited", excludes anything else from happening.
In plain English, you told the aircraft to loiter until the end of times, when in auto.
Do manual take off, manual loiter, then auto task."
