Multirotor, multicopter and quadcopter discussion - The Drone thread

Thanks :)....Put gopro in auto photo mode 12mp (0.5 a second). Flew up and done a slow look around.

Then chose around 9 of them each slightly further panned around. Then used CS6 wide lens correction tool and manually defisheye each one and leveled the horizon.

Then from within adobe bridge selected them and went to 'tools / photoshop / photomerge' and let CS6 do the rest and finally adjusted contrast etc. It's not perfect and I'm not happy with the size of boats in foreground or the sun washing out photo, but came out ok.

I believe lightroom 5.2 handles the defisheye much easier as it has a gopro profile

edit: here is the full size photo, over 7000px wide

The GoPro lens correction profile is a function of Adobe Camera Raw 8.2. You can grab a beta from adobe and they do a version for CS6.

Re: Tripcopters - what's the benefit over a quad bar buying a few less bits? I'd have thought they wouldn't have been as agile or as stable as a plain quad.

One less ESC and motor, and some prefer the yaw control over quads. They are very different beasts in the air. Check out RCExplorers Tricopter builds, stability really isn't an issue and tricopters make great FPV platforms

can you control yaw in a quad?
Nevermind, read the wiki

X4 arrived just now and it's an excellent piece of kit. Having a bit of a problem getting it to hover steady and not drift in a direction. Adjusting the trim helps but can't get it spot on, i.e. steady hover with stick neutral. Any ideas or am I just asking too much of it?
 
It should not pull to much... Have you run the gyro cal before takeoff ?

put your trims back to zero....put it on dead flat surface. Hold the left stick to bottom right and waggle the right stick left right left right etc till the hubsan lights flash

If it still pulls try the trim again

It's best to do gyro cal before every takeoff or after crash

I just tried it, left stick to bottom right side. While holding it there, waggle right stick side to side, blue lights on hubsan blink

Takes no more than a couple of waggles
 
Do you need to do anything else first like its on power up or just at any time with the X4 and control switched on and the X4 sat on a flat surface?
 
No should be fine can do anytime, as long as both powered up. Very weird

You could try the cal in expert mode, so push down and click right stick so it says expert. (Power light will flash red green) ...Then try the cal. Don't forget to push down on right stick to put in normal mode again
 
could I be missing something on "mode 1" and "mode 2"? I notice different ways of doing things depending on the mode but seem to have missed any explanation as to what the modes are and how (if?) you switch between them.

I'm clearly having a think afternoon :) :D
 
Quite a nice vid of the phantom here. Liking the bit with the Ariel Atom :)


Unsure of how to embed the youtube vid? :(
