About Me:
My background and education is in software engineering. I'm also co-owner of a small business that does product development and manufacturing, global sourcing, and retail sales on Amazon.com.
Please tell us a bit about your UAV interest
I'm interested in software and hardware development for anything that flies.

"No, sorry, I haven't worked on the ArduPhantom in months. Moving on to other projects."
"It's been a big problem for me with the DJI Phantom ESCs. It's impossible to get them to all start/stop spinning together at the same PWM threshold. Which makes it easy to flop over on takeoff or landing."
"Hi Chris,
I've put an APM in the case of a Phantom 1 (see http://diydrones.com/profiles/blogs/arduphantom-apm-arducopter-in-a...), but Phantom 2 may be more difficult. The Phantom 1 ESCs can connect directly to the APM outputs, but I believe the…"

"Thanks. A bit disappointed that the Spline in V3.2 isn't nearly as smooth as my original SplineNav 0.3, but hopefully the devs will refine it over time. "
"The latest release has spline segments in Auto mode, but they don't seem to work very well yet, so for now I would still suggest installing my SplineNav 0.3 from GitHub."
"Sorry, dunno how that happened, fixed."
"Seems like the issue with trees can vary a lot by tree type. Needle trees like pine don't seem to have much affect, but broadleaf trees are a much bigger problem, perhaps due to the high moisture content of their trunks.

"Hi Roger,
I made my ArduPhantom from spare parts, no conversion, so I never had an actual Phantom LED. I used regular LEDs from Radio Shack, wired directly to the APM's LED pins with a voltage drop resistor on each."

"Hi Kumaresan, I'm not familiar with the Arduplane code, but it seems like it should be possible. To see the changes that make up SplineNav you can go on GitHub and do a compare between SplineNav 0.4 and Arducopter 3.1. That will show you each line…"
"Hi Roger,
No, I did not calibrate the stock Phantom ESCs, the stock calibration seems to work fine.
However you'll probably need to increase MOT_SPIN_ARMED and THR_MIN to something like 175 to 185.
Regards,
David"

"Yes, I've seen plenty of videos already, it's what started this whole thread after all.
Also, the problem I'm having is mainly behind trees; flying behind buildings isn't as bad."

"I'm using Circular Wireless SPW12 antennas on both Tx and Rx. Unless I want to go far instead of flying around close to myself, then I use the Circular Wireless HELIAXIAL12 on the Rx side."
"I guess it's possible, but considering that it works just fine behind small buildings and it works fine at large distances, I don't think it's a setup issue. The reason it doesn't work flying behind trees is that all the trunks and branches cause…"
"So I went ahead and got the latest 1000mW Lawmate 1.2 GHz transmitter and receiver. Through-trees performance is better than the RMRC equipment, and I also get an extra minute of flight time, since the tx only weighs 25 grams vs. RMRC's 72 grams.…"
"Hi Zidlov. Great to hear about your SplineNav test. No, SplineNav doesn't affect the behavior of other flight modes, so it must be a separate issue."
"Well, it hasn't been tested on Pixhawk, but it should work. Let us know your results!"
