Hence the reason pilots license required, that alone is going to weed out many.:tennis:

Follow the Nasa guidelines on soldering or crimp connections, and it's not an issue. http://workmanship.nasa.gov/lib/insp/2%20books/frameset.html

This says it all! "I appear to have uncovered a rats nest of intermittent signals between the Herk breakout board and the Herk itself" '

It's funny how the two top posters, one with an actual commercial business in the film industry are NOT using Herk boards.:tennis:

Don't think so. KDEXF-UAS75HV KDE DIRECT XF UAS ESC, 75A+ HV x8 $1,168 Not cheaper!:tennis: K

Nope , don't need experience with that board to know you don't have any redundancy with a single combo board as you do with single esc's with logging capability. It's common sense.

What ever you think dude, single esc's are a much better config than that over priced piece of garbage.

Get rid of that herk board, that thing is an accident waiting to happen.

Gary, I wouldn't worry to much, these lipos are fine. User error mostly. Mine is holding good IR numbers.:tennis:

What brand charger are you using? If it's charging them to 4.4 volts per cell, that's your problem. 4.2 absolute max.

5 to 6 volts with built in driver, with or without signal wire...but when all are connected to your receiver signal they all flash in sync. In the last video i posted they are random, because transmitter wasn't powered up. I use a 6 volt park bec to power them.

I can see them in full sun with dark sunglasses. The first video was at 5 volts, here's a shot of them today so you can get an idea...... I know the strobes are over 400 lumen flash.

Strobons, red and green with white strobes front. Single white strobes rear, miniscule draw. Can be seen for miles. http://flytron.com/light-systems/185-strobon-xl-navigation-strobe-red.html http://flytron.com/light-systems/99-strobon-navigation-strobe-light.html...

Was the crash cause the esc motor sync issue?

Not a good idea...you want to keep esc to battery wires as short as possible, extend the esc to motor wires if you need more length. Solder and heat shrink everything, the only bullets used should be the battery connection.

No SimonK here either.

No not really because it fly's locked in at about 1.4 but jitters in fast flight and has vibes from frame in the video from my gimbal in anything more then calm wind. Video is best at 1.2, and at 1.9 you can really start to see the jitters, but know where near uncontrollable. I can strap my...

I've been testing gains and so far 1.3 to 1.4 works best. I have 15" props coming today and wanted to see how high i could go. Wayne , same boat here with rigidity ....bird doesn't get crazy on either end of the gain settings. My logs at 1.9 and 1.5 pitch and roll, height and yaw 1.0. 1.9...

You would remove a lot of weight and unnessary wind resistance by removing those butt connectors and getting the motor wires inside of the tubes. Cut those rail tubes shorter.
