Bob Eisenman Posted August 2, 2018 Author Share Posted August 2, 2018 A bit off topic (FPV drone racing) but I wanted to try hovering the Cheerson CX17 drone (camera) in more optimal lighting. Quote Link to comment Share on other sites More sharing options...
steve454 Posted August 5, 2018 Share Posted August 5, 2018 (edited) This channel has many reviews of drones and quadcopters. I used to watch it more when I was flying my Syma X8, a cheap clone of a Phantom with no GPS. Had a lot of fun going up about 200 feet and doing slow rotation with the camera recording to a micro SD card, then watching the video on the computer. My only GPS quadcopter was a Cheerson CX-20, which crashed when a prop came off, after that it wouldn't fly right. https://www.youtube.com/channel/UC90A4JdsSoFm1Okfu0DHTuQ/featured Edited August 5, 2018 by steve454 Quote Link to comment Share on other sites More sharing options...

Ground scan stabilization makes for a stable hover. CX 20 is a big one! 1 Quote Link to comment Share on other sites More sharing options...
Bob Eisenman Posted August 8, 2018 Author Share Posted August 8, 2018 @steve454 Motion sensing drone auto correction ..... A thought. BoofCV: If you use an Android phone and it can run 'BoofCV' from the app store it has a bunch of demos of computer vision. This one is called KLT pyramid tracking. Motion between video image frames becomes displayed as a line from points on the tracked object. The length of the line is magnitude of change and the direction is as shown by the line. Perhaps ground sensor assisted drone auto hover using ground image detection and processing uses something similar to cause software-directional-change input to the drone resulting in a stable hover over a place at a given altitude. Plus GPS input as well! Quote Link to comment Share on other sites More sharing options...

In the air is a model with a prop diameter of about 10 inches. 1 Quote Link to comment Share on other sites More sharing options...

Are you sure, that seems an awfully small prop for a 4-stroke motor? It would have to have a motor of less than 0.40 cu in to be as small as 10” Even the little foamy biplane I’m flying below has a 12” prop: Quote Link to comment Share on other sites More sharing options...

It could easily have been a few inches larger. When starting it with his hand his 4 fingers were smaller than the section of prop he was turning. He jumped back with each attempt to start it (6 or more turns). I took a rough guess at the prop size based on his hand size as seen from the distance in the video. Here it is on the ground (P51 Mustang?) The wind sock is a 'for real airport sized' one. The clubs website in Facebook is https://m.facebook.com/Plumislandrcflyers/posts A jet flew before it. Nice video of you and your flying field...the runway is a bit short though. 1 Quote Link to comment Share on other sites More sharing options...
Bob Eisenman Posted August 10, 2018 Author Share Posted August 10, 2018 I sent the Yuneec Breeze up to 150 feet just after sunset. 2 Quote Link to comment Share on other sites More sharing options...
ir_fuel Posted August 17, 2018 Share Posted August 17, 2018 This is an FPV drone :p EMAX Hawk 5 on which I installed a self-designed GoPro Session mount. This was a test of that GoPro mount. I'm not an expert flyer This is without stabilisation as you can notice 1 Quote Link to comment Share on other sites More sharing options...
Bob Eisenman Posted August 22, 2018 Author Share Posted August 22, 2018 Great video clarity! Big flying spot! Most of what I know comes from 'quadcopter101' https://youtu.be/pK4esYLAvH4 That jet looks like it's landing at 1:24 in the video....maybe near Brussels? I'm still struggling to fly gates with 'freerider'. Quote Link to comment Share on other sites More sharing options...
Circuitmage Posted June 19, 2020 Share Posted June 19, 2020 Found this thread on here and thought I would share my first FPV drone video. It's 10 mins long, with each battery running about 3 minutes, so be prepared...but if you want to see what I do with my TinyHawk2...enjoy!
