Clarence Casper replied to Darius Jack's discussion UAS Certification UAS Certification Certification Certification in ArduCopter User Group
"Darius, You have jumped to an extreme conclusion, today FAA regulations span a range of aircraft types, from commercial transport to general aviation, to experimental.
As an example, the electronics in my Piper Arrow are vastly different from the…"

Clarence Casper replied to Bill Harrison's discussion Looking for input - tethered Quad platform to fly communication antenna
""Any thoughts on the Naze being able to maintain level hover despite wind or movement of the operator on the ground?  We are not running a GPS and don't want to."
Trick is to be able to measure tension angle vector of antenna relative to drone,…"

Clarence Casper replied to Darius Jack's discussion VTOL Copter Plane Catamaran Hybrid in ArduCopter User Group
"What is the advantage over a fixed floating electronic sentry, with wireless link and solar battery charging?
Perhaps a tethered blimp, if you must fly?
Probably best to transmit raw sensor data and do real-time image processing at home base.
Around…"

Clarence Casper replied to Dennis Megarry's discussion APM Pro with E800's on Tarot 650 Frame, motor issue..
""I tried moving the servo wires to a different motor and the problem occurs on the new motor and the original works fine"
What do you mean by servo wires?
If you moved the PWM input to a different ESC/Motor pair, the problem is not ESC/Motor. But…"

"I have enclosed the text of the FAA press release, as a pilot I subscribe to FAA releases, the important part is registration is free for the first 30 days.
Following is the FAA release:

Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
"I'm sorry Martin, which "basic circuit knowledge" are you referring to?"

Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
"I agree, but if you do go parallel, make sure you use a battery monitor/alarm on both batteries.
If you need redundancy, go with a coax-quad, with one battery driving the upper motors and one driving the lower motors, as an example."

Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
""as being wired in parallel both packs have the same terminal voltage"
Correct, and that voltage will be controlled by the strongest source, i.e. the good battery, and current will flow into the bad battery, from the good, just like it would from a…"

Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
"Yes and no, during normal operation, both battery packs resistance increases as they discharge, failure modes are another story, from an informative battery site;
"There are several possible failure modes associated with the complete breakdown of…"

Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
"No, you would not have enough current to sustain flight as most current would be going into the failed battery, unless the cell failed open. You would need isolation circuitry to save the flight."
Oct 17, 2015
Clarence Casper replied to Aussie in AZ's discussion 1 battery vs 2 batteries that equal the same mah?
"If you lose one cell in parallel batteries, the good battery is going to try to charge the bad battery, the overall voltage will drop to whatever the the lowest charge voltage the bad bad battery can develop under that charge, in any case the…"
