A Tarot 680 Pro I built a couple of years ago - flew great, but suffered a devastating crash when loss of radio signal caused the motors to shut down as I did not have the failsafe enabled.

Welcome to the world of quadcopter problem solving. From my experience, your best bet is to troubleshoot down to the LRU (line replaceable unit) and then replace. Start with replacing the F.C. and work from there. Hold onto the item you're replacing in case that you guessed wrong and the thing...

I searched and from what I found, I suspect that public access is available only via tours: https://www.nnss.gov/pages/PublicAffairsOutreach/NNSStours.html I could not find anything else about Yucca Flats in particular other than it is one of four test regions within the Nevada Test Site...

When I did my test flight of my homemade Faraday cage surrounding my vtx, I didn't mention that I had control issues. I had intended to fly a short mission, letting the autopilot fly the aircraft while I watched the video on my monitor. But as soon as I switched on the autopilot, the copter took...

Just a comment or two: I used to live in Az. (Fountain Hills), though that was before I got into this hobby. Be extremely careful about flying in any parks as most do not allow drones as they are a noise nuisance as well as a disturbance to wildlife. Watch out in particular for Maricopa County...

If you are having lots of noise coming from ESC's try wrapping your transmitter in lint trap mesh.

I had the same thought! But then I ws wondering how would he retrieve the video? For awhile, it is inverted as it descends, then later, when close to the ground he hovers awhile before landing - amazing endurance, especially considering the temperature!

In the last two days, I've read about an amazing altitude achieved by a DJI Mavic: Then, today, I read that a Russian guy topped that - 33,000 ft! https://www.diyphotography.net/this-guy-flies-a-small-hobby-drone-up-to-33000-feet/

Uh, guess that was lost on me.... :cool:

What's with drone pilots in the UK? http://www.thedrive.com/tech/19417/airplane-drone-near-misses-in-the-u-k-have-more-than-tripled-in-two-years

I really need you guys to keep working in order to help subsidize my retirement! ;-)

The color is, um, special...

the last couple of times I've flown my elev-8, I've had problems with two flight modes that require GPS/compass: Loiter and RTL I recalibrated the compass twice now - the latest time, I compared the compass heading as shown in Mission Planner with the compasy on my iPhone and there was only a...

You have idiots in any group. It is unfair to make generalizations about a group based on the actions of one or a few individuals. I'm speaking as a "Bad Hombre", who was born in Mexico and came to the U.S. when I was a baby, grew up and got an education here in the U.S....

Here is video of my efforts to improve FPV video quality - got a little better performance with a circular antenna on the quad, but still not good enough. Also, Loiter mode still isn't working...

So, I had a scare yesterday. I wanted to fly my quadcopter that has an fpv camera and vtx installed on it. Attached to my transmitter is a monitor/receiver/dvr - wanted to record the flight on the dvr, but shortly after takeoff the video got choppy and the monitor blue-screened. While I was...

When I was in jr high, I briefly considered dropping a couple of tubes of "Bangsite" into a manhole that was in the street near my house and then putting a road flare near the opening. Fortunately, I didn't have the guts to do it!

When I was considering which branch to enter, I always wondered about the marines - did basic training make them crazy or did the marines attract crazy people? I decided to steer clear. Spork, I think you made the right choice!

I have agonized over the same thing. I intended to study and get the technician's license, but didn't follow through. I now have two aircraft each have a 600 mW video transmitter and I have rationalized that as long as I'm not interfering with anybody no harm no foul. But how do I know if I'm...

The cannon looks to me like the kind that uses calcium carbide. As a kid, I had one that looked like that. It came with powdered calcium carbide that you put in a chamber at the top. The cannon had some water and when you depressed a button, a small measured amount of carbide fell into the water...
