Camera angle too extreme to land -
#1
Simply put, while experimenting with more extreme camera angle, likely about 60 degrees...I noted that upon lending, the ground was not longer in the picture.  This ended with people flying in all directions and destruction on a legendary scale!  Actually, it ended with a few broken standoffs and our favorite fern being trimmed, but otherwise no damage.

The question, I really enjoyed the increased angle of attack in normal flight.  KT-Mini was really able to stretch legs and sing through the air.  The only issue was in attempting to land.  Short of a gimble system, how do we land when we cannot see the ground any longer?

I know that people with extreme angles land near something tall, like tree. Tall object will still be in the field of view, and basing on it you can determine and control your speed and altitude.

I'm flying with camera raised ~30 degrees, which makes it hard to fly slowly before landing (I often don't see enough objects on ground to determine speed and altitude) - I rely on OSD attitude indicator, which accuracy is ok when flying slowly.
Feel like constantly chasing perfection. Once you think you almost got it, see how far you are really.

Thank you!  That makes a lot of sense. Need to choose a few landmarks to kind of position things.  I have had my camera at about 30 to 35 degrees since I installed it and was trying something new.  Installed a 2.1mm lens as well, slightly wider FOV and it is the same as what is on my Swift Micro 2.  The loss of ground was something I failed to consider when I took off  Dodgy I really liked the way it effected my flying, having the angle that intense, but I feel like I should relax it a little and maybe ground test it first.  Buzzing the fern was not the hi-lite of my flying today!  To make it worse, we had about 15 people at our home for a meal and I think it is the only time everyone was looking in the same direction when I boo'd!   Tongue

I've recently bumped up my camera angle, but not quite as much as you. I fly at about 45 degrees now, maybe a little more depending on the quad and how much I can tweak the angle. One of the reasons I didn't use more aggressive camera angle was because of some of the problems you both are mentioning. Being able to land with a higher angle I think also requires being able to hover and fly slow at a higher angle.

The good news is, it's not much of a stretch to get used to hovering with the increased angle, and going slow comes naturally after you get the hover back under control. If you were to spend one or two flying days working on hovering here and there or an hour or two on simulator you should find that you can hover, go backwards, slow down, etc with less angle... It's a matter of spacial awareness without being able to see your point of reference... you have to be able to hover, and then to imagine the ground below you lol...

FOV is a huge help as well, and tall object to reference is a good idea as well... I might try bumping up another 10-15 degrees to give it a try this weekend.

Do a quick 180 and fall backwards to land, you can look down and use throttle to brake while falling backwards.

I second that!

I will try the practice with hovering around objects tall enough to help stabilize me. I will also practice the 180 as it seems like with the two things together, camera angle may end up being a non issue. Thanx everyone!

I've been learning the same thing. Here is JB's take on it.

Flying: Talon 6S 6" 2407s 381g no bat, Martian 3, 5" 2205s sooo heavy + gopro session 5 573g AUW, Aurora 5" 2205s 280g no bat, Druckbaer 3" 1404s 172g AUW 3S 550, BQE Megapixel 2.5" 1107s 139g AUW 3S 550, BabyHawk R 2.5" 164g AUW 3S 550 (stock except microeagle, CRSF, 2.5" arms) and maybe 3 more, for now...

McDee, this is perfect! I like the idea of sliding in to a landing Smile

Taking a flag with you also helps.
I tend to fly on wide open meadows quite a bit and it help to create a tall reference point.
Check out my videos @ www.youtube.com/Marcelfint and let me know what you think!

when i fly with a lot of up tilt i just do some very sharp orbits close to the spot i want to land and when im around a foot off the ground i just drop the throttle, takes a bit of practice but at least you can see forward

did see this to late maybe, it is all about practice and feeling, as @fint say search for a reference point like a tree, let's say there are 3m between ground and the first boughs are there, so you know you have about 3m to the ground. Fly to the tree hovering on the 3m high and then lowering the throttle and slowly sink town. The hardest thing will be hovering on the high but with a tree, you have always a reference point on top which you can see.

You will see doing this for a couple of times will improving your landing skills fast and you copter control too.
Fly deep, fast and crash - repair and then repeat! Welcome to the Game of Drones ;)

Far fetchead: attach a servo to control camera angle, and have a three-position switch choose between "Warp Speed", "Cruising Along", and "Landing Time!"

Prob. not feasible on smaller builds, but maybe something worth considering when building slightly larger?

I looked into a changeable camera angle and came to the conclusion that developing the skill to fly and land with a steep camera angle was a worthy pursuit. An automated camera angle would detract from a pilot developing these important skills.

Here is the latest thread on the subject, I posted links to the method Propwashed used for their solution in the thread. http://intofpv.com/t-automated-fpv-camera-tilted-angle
