Looks awesome!! Were they easy to fly around in there?

Will have been very easy, I fly my inspire around my living room which is tiny. Very confidence inspiring (sorry) devices. With a modicum of skill you would be able to get some great aerial shots in that sized hall :cool:

Have you got videos?

Flukester · 13 May 2015 at 17:07

I dunno, I would not fly a £1800 UAV in a hall stacked with all those lights dangling down... but hey that's just me and I'm poor lol

Anyone seen those 5.8Ghz cloverleaf antenna's someone linked before? I cant find any of the decent ones on ebay (the were metal coax cloverleaf, had a black stem)

Apparently outperformed most of the £15 cloverlead ones on the bay

However no where to be seen... Im going to need a converter too, as my fatshark goggles has one type of connector, and my vtx has another

Or will these do?

Apprently the ones I want are made by someone called gav.

Just done a 6 mile trip on my phantom 3 proffesional. had problems with gimbal and had lines going into image when was flying downwind. coming back lines had gone. come home calibrated gimbal and picture is loads better.

linky.

still had full rc signal and full video signal, range on these is amazing. recorded in 4k.

You need to calibrate your gimball down (normally 3 or so degrees) to avoid the rotors ruining an otherwise good video

Verified phatom owner flying over railway lines, houses and roads. Good job

chance to fly after work today with the nicer weather. Gimbal is now controlled by a 3 way switch. Need to tweak the settings when the gimbal is rotated 90deg down. Bit gittery.

Genuine lol

e: video is private now, but I imagine it being the same as any number of YouTube Phantom videos :/

4 yellow foam earplugs and 2 bits of plastic

Cuts out all the vibration pretty well

I think you might need to balance your props/motors dude. Video looks like the gopro was mounted to a bunch of fat birds trampolining on pogo sticks around in a mattress factory

Good work otherwise!

lol. Nice description

I've got some softer isolating rubber grommets i might try. The ones that came with the gimbal are pretty solid which isnt helping me thinks. Reduced a fair amount of the jelly effect by fitting an ND8 neutral density filter. Other videos shot in sunshine were pretty bad in places.
I'm learning more & more along with emptying the wallet quicker and i thought archery and photography were money pits

DJMK4 · 14 May 2015 at 08:54

I think I am going to swap back to my white DJI legs, think it flies much better, and make something like you made above

Only problem is the landing on white legs is a little more tricky in FPV, would either have to be very gentle otherwise it topples over, or hover and land LOS.

It's cheaper to balance your props and motors! There's a couple of good vids on youtube that show how to dynamically balance motors. You just need a vibration sensing app for your smartphone.

Basic theory is;

Props off
Put phone on top of craft
Spin up one motor at a time, clock vibes on phone
Make a mark on the motor with a sharpie or something
use a piece of VERY sticky tape or a small cable tie around the motor
Spin up motor again
<vibes that's the side of motor that needs weighting
>vibes it's the other side that need weighting
Keep moving the tape/cable tie around until you're at the point of least vibes
Mark again so you don't lose the spot
Then it's just a case of adding some epoxy inside the motor to permanently
weight it at the right place.

Balance your props first though, it's a lot easier and quicker!

gandhi · 14 May 2015 at 09:49

Generally, I don't tend to bother too much as the smaller motors and props don't seem to be too bad.

Terrible day yesterday. Batteries all charged up for lunchtime sunny flying and our sodding accountant came in for a day long meeting. Bah.

And then the blimmin g/f wanted to go and spend the whole evening sat in a pub beer garden for some reason!

Still, there's always the weekend I guess

Cheers for that. Something to keep me busy over the weekend.
Not a straightforward job balancing the props as they are self tightening. But found someone selling a CW/CCW threaded balance rod. Mucho cheap too.

Django, is it worth the upgrade to an inspire?? I have just a phantom at the moment. I notice you have 2! Greedy? Haha
