"Try a x 16 as shown in the pic. We did one for a military customer years ago. Meets your weight and payload requirements. Let me know if you interested and I can send you the files."

Jeff Zika replied to iskess's discussion Redundant Systems
"This appears to happen without a GPS lock in all modes except stabilize and manual. Just flies right into the ground. (lost GPS lock a few times last week)"

Jeff Zika replied to iskess's discussion Redundant Systems
"I did some work in this area last year. We never built the system designed but it should work. We decided to go with redundant receivers, one connected to the APM and one not. The key was to use a PowerBox receiver failsafe system. All the servo…"

Jeff Zika commented on u4eake's blog post Crossing the English Channel (France-England) and back autonomously
"This has been tried, and using an APM. Couldn't do it do to the French. They ended up doing a flight to an island that was the same distance. . It was all on TV done my James May (Top Gear). It's all on YouTube.

Oh, and they did it with a glider!"

Jeff Zika replied to Vince Hogg's discussion De-shaking, editing frustrations gopro.
"There is a workflow required for Virtualdub deshaking and you are doing on a few of the steps. These are what we do:

1. Convert the video to divx or avi raw from out-of-camera format using WinX HD Converter.
2. Run Virtualdub/Deshaker process with…"

Jeff Zika commented on lot's blog post Quad copter flying for 4-8 hours
"Ok, these "look" like E-Flight 52. Even if they are as large as the 160 there is no way this thing is getting more than 20 min flight time (E-Flite Power 160, 10s4p6000, 20x6, 500g frame weight, 11kg GW) Other setups can get as much as 20kg GW with…"

"50lbs lift capacity? 1.5m frame width? 100m range (with satellite, maybe???). Who are they kidding?

Now I've been designing multirotors for a while now and NOTHING with only 4 rotors is going to meet these specs. Law of diminishing returns...

Can…"

Jeff Zika commented on Chris Anderson's blog post ArduPlane home page
"Ok here is a weird one. On long tracks between waypoints greater than 64km apart, approx every 5 minutes the autopilot goes offline resulting in a hard dive, random roll, and throttle to idle. It recovers in 1-2 seconds, stabilizes the aircraft, and…"

"Try this. Rough but close enough. No object file (thus no livery). Flight model only.

"Thank you for all the quick responses...

Like I said, I am evaluating several different systems APM just being one of them. The open source model is preferred so we have access to the source code for changes, at least at this point.

"Ok, this is the first post to Arduplane group so please bear with me. 

We are evaluating and testing autopilots for a high speed target drone, as in 200knot + and up to 10000ft alt. I have been working with an APM1 running Arduplane 2.4 in HIL mode…"

Here is a test video from a new folding, packable waterproof quad made from alum and off the shelf hardware store components. The speed controllers are cooled by mounting on an alum plate that forms the base structural component of the design. The…
