Tarot FY 680 and a bit Hexacopter

Just steal from Ian's house  :P

Lol very nice Marcin :)

Well the vibrations looked fine inside, after an initial outdoor flight ( in high wind ) it seems like its jello hell lol

I also had a problem with my pitch servo vibrating on the gimbal, any contact would set it off. After a while I found I could stop this by applying pressure to the pitch servo. I whipped it out and mounted it to the outside of the gimbal not from the inside, problem solved :)

So another living room test flight showed no vibrations again. Waiting for the wind to die down for another attempt.

So that's your radio controlled method of doing the household dusting is it ??

PS Lots of Tarot parts here if you get stuck with China - this is in Taiwan - takes 3 days for them to fly stuff to Coventry, then only 3 weeks for Customs to clear them !!

Hehehe, I don`t know about dusting, but it gets rid of rubbish :)

Here was another forced indoor test, just to see if gimbal was better after I reworked it. Needs a tweak to the roll gain I think, but was more concerned with vibrations

And yes, right at the end when it sounds for a split second something going through the props ................ It was :) It was white, paper like, with writing of some sort on it :) Not sure what it was but early reports indicate Donna has not missed it so it couldnt have been too important :)

its certainly getting there now bud, with such a big bird inside the house, there's a lot of turbulent air blowing around, lets hop it wasn't your tenancy agreement papers.  :laugh:

Had it out for a first proper flight today. Just trying to get GPS to hold, that failed but Jim mentioned something that I had overlook ed so will try again tomorrow.

This reply is sort of a note for myself more than anything.

I had the timer set to count up and just did mild flying waiting for the lipo alarm to go off and land to see how long my 5000mah 4S would give me.

Instead, no alarm went off, but out of the blue my Hex landed all by itself with no input from me. I immediately though bugger I`ve killed the lipo because I had low voltage protection turned off. As it turned out when I got back it was in fact on, so it had landed itself.

The values were :

Total flight time before auto land : 7:20
On landing 37% of lipo still remained
Cells were 3.8 3.77 3.78 3.8
Charger put 2845ma back in leaving 1155ma available

2845 gave 7 mins 20  ( 440 seconds ) so 6.5ma per second
1155 left means an additional 2mins 57 seconds  ( 177 seconds )

So in theory :) 10 mins 17 flight time leaving 20% of a 5000mah 4S

So I still had 0.1v to loose from each cell so I could drop my low voltage value by 0.4v I have reprogrammed this for the 0.4v and will try again, with lipo alarm still on and see how much longer I get while still saving 20% of the lipo`s capacity.

Adding the second lipo will not exactly double it of course, but I would think 15 mins is no problem.

Nope sadly not, jello still there :(

looking good.
gunna order one of these when chinese new yr finishes..hopefully the brushless gimbals be out then..

Finally sussed out the GPS drift problem from yesterday thanks to Jim :) .

PK got wind of the success and an offer to film at a skate park for a promotional video so decided to pop over. Of course I hadnt even tried mounting a HD camera so had no idea how much of the jello would be seen on a GoPro.  Paul came down with his GoPro and we went out so test it.

Few points :

This was not a flight, it was to check jello

Some of the movement was because I was giving strong movements pushing the gimbal hard, Paul wanted to film 3rd person to show the throws the gimbal was fighting against.

I pointed the Gopro up to see the arms on purpose.

anyway, just a test, no stabilization used, just raw GoPro, not bad for a £20 gimbal I say :)

Looks pretty well sorted now.

Great being able to tilt the gimbal up and down manually from the transmitter.

Wow you've got to be happy with that - nice one.

[g.collins]

That's flying great Ian, I love it when a plan comes together, I see your a pincher, I'm a thumb man, feels weird if I pinch.
;D G
