This morning, we had some calm air for a change, so I took my Tarot 650 Sport out to the field for an endurance flight test. This is a large copter, weighing around 3KG and powered by a 6000 mAH 6S lipo. I've estimated my expected endurance time, given current draw for mid throttle setting and...

I'm not sure what you're asking as the term "controller" has been used to in the following contexts: Flight Controller, R/C transmitter. IF you are asking about a flight controller, then there are plenty of them out there - all should work, but not all offer the same functionality, so it depends...

You didn't mention if you are watching video from the aircraft via a monitor or googles - if that's the case, you need to be aware of significant latency introduced by the GoPro cameras which can get you into a bind. If I'm shooting video while flying the aircraft manually, I do not bother...

For those who believe that life is flat and not spherical ;)

I SERIOUSLY doubt that the email came from the IRS - they do not send unsolicited emails. I would be VERY wary of any email purportedly being from the IRS claiming that you owe money. They send conventional (snail) mail to you.

Sorry if I came on a little strong... I thought you were serious about your initial remark regarding RTL, and in retrospect, I think you were just being lighthearted.. In my own experiences RTL has saved my bacon (as well as aircraft) several times, and I always make sure that it is one of the...

Here's a video of a short test flight:

I had been flying my Tarot 650 Sport quad with 13"props and decided that since I have T-Motor MN3520 motors, I'd go with 15" x 5 props. I ordered then a LONG time ago and they finally arrived from China. Here is how it looks now: The aircraft weighs 3.1 KG AUP (6000 mAH 6S lipo and a small...

RTH is for sissies? Are you kidding us??? You got your aircraft back, didn't you? What's better - being a "man" and losing your aircraft, or worse - having it crash into someone/something? Sounds like you have no compass display/OSD?? Even so, simply doing a 180 isn't going to help you unless...

No, that's out POTUS.

This is a smoking deal! If I hadn't just dropped $400 for a Parrot Disco I would buy this! somebody is gonna snap it up...

The takeoff looked good. I suspect that there was something wrong with the GPS/compass and when the pilot switched to autopilot, it eh aircraft toilet-bowled into the building. Perhaps he should have first put the aircraft into a Loiter mode, which requires working GPS/compass - it it holds...

Does it matter? I suspect not.

Good luck with that - doubt that customer support will be very responsive!

Don't know. If the GPS/compass was not calibrated properly I don't know if collision avoidance sensors would have helped much. I think they should have programmed a waypoint very close to the launch area where it drone would loiter in place for a few seconds - this would confirm that the...

Okay, it's not a quadcopter - looks like a hex with dual motors on each boom: https://dronedj.com/2018/04/02/russian-postal-drone-crashes/ Looks to me like it toilet-bowled at high speed - wonder if the compass was properly calibrated.

When you said "Perch like a bird", I expected something like this:

Yeah, it is a foamy, but there isa lot of tech in it as well - flight controller, gimbal withcamera, etc.

Heard of the Parrot Disco? It is a flying wing that has some pretty cool features, but many were put off by the price. But since DJI has dominated the industry, Parrot became one of the casualties, and has discontinued the Disco. But there are vendors out there that have Discos in stock and are...

Well, I've given up... Adding caps didn't help much and after trading emails with a couple of E.E. buddies, they have convinced me that I need to shield the three wires going from each ESC to its respective motor. This could be done by taking some coax, cutting along the length and stripping out...
