What are the error messages? Sent from my iPad using PhantomPilots mobile app

I've thought of doing something very similar. Crank it back up at like 1000 feet or something. 3 m/sec, or a little faster, is about as fast as I can depend without bottoming out the stick. I doubt you could start it up from an accidental motor stopping. Trying to start it with the compass...

3.4 km is pushing it, my spreadsheet showed me something that kinda surprised me,,,maybe I'm missing something. But it takes almost as much battery to descend as it does to climb...the power consumption was about 1/2, but it took twice as long. In fact, with a stock 68 watt hour battery, I...

I'd donate mine to the cause, but I'm kinda fond of it. DJI removed my limitations. I had to sign waivers and non disclosure agreements about my firmware modifications, get witnesses, fax stuff back and forth...bottom line, I can spin up and fly on Will Rodgers international airports runways if...

The phantom and tracker are GPS receivers only....the tracker tx's on cellular frequencies, not gps frequencies, therefor, no interference, cellular frequencies are in the 2.4 ghz range, GPS is not...but I doubt they will mess with the Phantoms control frequencies either, never heard that was a...

"At any rate, it almost looks to me as if the lens hood hit the newly-mounted gimbal guard." I bet you are exactly right

You could use a small solid state relay that is switched on by the arms LED lights power supply ( DJI GO app controlled) to power anything you want. Other lights, horn, grabber, the relays "coil side uses almost no power, the load-side would be fed from the Phantoms battery Sent from my iPad...

It depends how far a weight is positioned from the fulcrum (the center of the axis motor.) 2g can be multiplied by distance. 2g positioned 2.5cm away would need to be counter balanced by 4g positioned 1.25 cm away on the opposite side. (Back of camera axis) I don't know the exact lengths...

Update,,,guess I'll find out about those power lines,,,,An Engineer from construction (I work for an Electrical Utility) wants me to fly and inspect some power lines about a mile off the main road. I told him it depended on elevation and he said he could get me within 1/2 mile if we went off...

A little over 100m, and a little faster than 50kph. That is roughly the height it has to fall to reach it's terminal velocity. No wind tunnel, but I gave it an airplanes wind resistance. (So it's actually probably lower and slower) So, your phantom falling from 6000 meters won't do any more...

DJI hires guys with scissors to patrol their NFZ's Sent from my iPad using PhantomPilots mobile app

DJI has a vested interest in not wanting it's quads falling from the skies...it can't control the quality of non-DJI batteries. Yes, it's your drone, but it is their reputation. Sent from my iPad using PhantomPilots mobile app

A P3P's gimble would probably snap with those maneuvers Sent from my iPad using PhantomPilots mobile app

I'm going to get a phantom 4...it looks so much less fragile Sent from my iPad using PhantomPilots mobile app

I wish my pickup would also top out at 200 mph, stop on a dime, and get 30 mpg...and haul my 5th wheel Sent from my iPad using PhantomPilots mobile app
