Oh look...3DR just got $30m in capital, and plan to invest in their plant in...Tijuana, Mexico.

Use ecalc.ch for working it out. - ESC choice is dictated by input volts and the maximum amp draw of the motors - Real world Amp draw figures can be considerably different to those stated - Be wary of just using amps; The MN series have quite low maximum watt ceilings (circa 300W). I know from...

Just watch the vid...wow it's way out. one cell was 4.34v! And the drain was uneven too....hmmm. My maxamps drain at 0.02 within each other across all cells, and only drops 0.1 under load.

Holy moly.....that's heeewwwwjjjj! :frog:

2 x 6000 will be notably heavier than a single 10000, and redundacy failure is a small risk - I've never heard of a cell failure in the air. You're likely to introduce chances of failure with double the connectors, a Y cable etc. I have 2 x maxamp 10900's, and they are *expensive*. But good! I...

Indeed. I've got the 2 axis, and out the crate the vibe balls are too soft (lots of lateral shudder), and pitch is an utter bastard to tune with a standard Nex5r with 18-50. High pitch, low amplitude vibes (feels like buzzing) destroy any clarity the video has. Getting it balanced was the easy...

Yup. Very bright, very hot and the controller is pretty big. Needs a channel on the Rx - bit annoying if you run static lights and don't need to switch stuff off and on. Also - while there are enough outputs, some will flash only.

Very sharp quality! What's your setup? (Iso, lens, shutter speed etc)

It's running off a 12v gryphon hyper Polaris with a ferris on input wires from the 6S. I use the same bec in my other 6S quad with an identical Martinez but a gopro gimbal not the ASP. Runs perfectly well and also runs my FPV glitch-free which is why I went with it again. So 3S, I guess. Dirty...

If the BEC was dirty (Gryphon, so not cheap rubbish), wouldn't it affect roll too? Roll is nailed. RF should be low too, as I have tried powering it with only this BEC attached to the PDB. A poorly wound motor sounds like an interesting proposition. I might try swapping the motors around - if...

On your side too. With a proper checklist and maintenance, you shouldn't be crashing at all on APM (pilot errors aside). I have flown mine all year, and the only (minor) crash I had was the transition from 2.9.1 to 3.0.1 and the compassmot requirement (which I failed to modify my craft for...

I know it's tongue-in-cheek post, but I'm not so sure. The DSLR's aren't really coming down in weight, so the true professional will still need them. And even if a RED lost 50% of it's weight, it would still be heavy. There's also the general flight dyamics; if you want video in windy...

It's all irrelevant if your gimbal is not optimised. Even small vibrations/buzzing from the motors will blur the image. A gimbal with *zero* motor or external vibration with a $200 camera will give better video than a buzzing gimbal with $10,000 of optics aboard.

+1 on ghostrider. One additional note: in colder weather (it's -5'c here in Switzerland), the voltage under load will drop further than normal, especially if you "juice it". Don't be tempted to ignore the 3.5v alarm - land as always. Your flight times will be shorter, but you'll be looking...

Ok, I'm running an out the box RCTimer ASP (RCtimer martinez controller, v49), with a nex5r, standard lens. It's fed from a 12V BEC (Gryphon). I've got roll totally locked in; no vibes, instant response, no lag, no over-compensation. On the tracking screen (front page of the tool) it barely...

The phantom became self aware. It realised it was a Phantom. Self-destruction was the only sane way out. :nevreness:

I ran a APM2.5 based quad with and without a 5' dihedral. It made chuff-all noticable difference to the flight characteristics, or to loiter. Battery life was - for all intents and purposes - identical. I'd like to see someone try it on a V4 though (eg TBS disco)...

Is one of your motor arms twisted? Or is your CoG off?

Wow...that's completely spanked. looks very similar to the symptoms I had when I my RC's RSSI went beserk. Luckily, my APM2.5 saved the day with a smooth RTL ;-)

This guy is an idiot. A CEO almost gets himself arrested over a $50 battery? And those are his negotiation "skills"? Good lord, my 5 year old daughter could do better than this.
