Multirotor, multicopter and quadcopter discussion - The Drone thread

My new toy iv had for a week after having 2 phantoms, And loving it :)

Had to down scale the size of these pics

Looking good :) looks like a beast


Anyone know if those USB simulator cables from HK or ebay will allow me to use Phoenix RC with my Taranis ?
 
Oopsy

Was really looking forward to a nice session yesterday evening; Warm, sunny, little wind. Batteries all charged up. First FPV flight managed to lose the quad. Dropped it doing a pitch roll in some long grass. Took me 20 minutes to find the thing.

Thought I'd do a bit of LOS and was trying those big loopy rolls (more like a barrel roll than a flip) yeah, not quite enough altitude....









1 snapped arm, 2 broken props, 1 destroyed FPV antenna, 1 crumpled battery.

Outch, keep the altitude up when doing rolls :(



Use your RSSI signal strength on the radio to take you nearer to the quad location, RSSI going down, your heading in the wrong direction, RSSI increasing, going in the right direction, RSSI around 80 warm, 85-95 very close I find.

You would be surprised at how handy RSSI is to locate a 5-15 meter radius around the quad, assuming the RF signal is not lost, its handy when taking goggles off and you have no idea where your quad is.

also if you think your props are not fancing down in mud, give the throttle around 5%.

I am able to quikly find mine in grass using above methods

How much is that going to cost to fix up?

As a last resort, it's an easy way to cook ESCs :p Assuming the battery survived that still connected, lost model beepers are quite good. I had mine set to blip when disarmed (5 seconds of no input disarmed it) using APM, but I don't think this is possible with 32bit controllers?

As a last resort indeed.
 
Unfortunately, it had spat the battery so I had no video link or RSSI when I lost it, and as it was FPV upsidedown and back to front when it went down, i had only a rough Idea where it had gone!

Normally I use a dayglo green battery strap, so it's a bit easier to find, but I left that home, idiotically.
 
Yep,

Doing that tonight! weather too nice not to. I have a couple of spare arms, so all good there. The battery was cheap, props are expendable. I'm most upset about my antenna. It was a very good and expensive one, not readily available on these shores! But still, you live and learn! I've just bought some new ones. These are encased, so much less susceptible to damage.

They're also on really stiff cable, so bend and hold their shape!

Not a cheap antenna fix then, :p

I found some more cool foam in work today, still toying with my FPV foam housing idea. This would actually be pretty cool for the front of it. It holds the camera in well.

that would fit pretty nice in my 250, with a housing I would be able to fit the main bulk of it in this housing, and then just have the wire leading to the vtx and antenna at the rear.

After replacing the motor on my Hubsan it seems that whilst it now takes off once more, the writing it already on the wall. After reaching a few feet (and after a few seconds) it begins to drift to the left dramatically. Adjusting the trim sends it flying to the right during takeoff and ultimately has no effect after a moment or two, the gyro looks well and truly knackered.

Reading around it seems this is fairly common with the Hubsan depending on the batch. I'll get in touch with the seller but not holding out much hope due to my having replaced a motor and crashed it a fair few time (not majorly mind you). I could replace the board myself but for the price and effort I could spend a bit more and buy it new, or upgrade to a cheap FPV (Syma or similar) model instead, and see if that side of the hobby interest me also. Sadly for my finances, I'm fairly certain it will :D

Alas, for the time being, the Hubsan is flyable in expert mode with a great deal of attention, but in normal mode will drift left even with full stick to the right. No amount of calibration or resetting can help me now :p.

Heh, got my micro stuck up a tree lunchtime. Had to abandon it to the gods of FPV until this afternoon :( Thankfully it was still there, and some plastic pipes lashed together and much swearing later got it back. 4 and a bit hours later, with the FPV still running, I measured the battery voltage (fearing it had run the lipo to death), it was showing 3.65v! Gotta love Nanotechs :D
 
i have sold my quad and going to ship it in original packaging. what courier can i use because it contains 2 lipo battery. im wanting to insure the package. thanks in response ;)

What quad did you sell? why did you sell up?

If anyone is getting rid of any 8 channel FrSky RX's let me know

I would say use whoever hobbyking use, but I cant remember what they were sent as, most of the courior websites will tell you what you can and cant send, check the sites.

Haven't been flying at all the last 8 or 9 days, finally have my quad built but only one battery that is big enough to fly the thing, i will have to order some more when they are in stock.

Im going to see what weight i can cut as it is sitting at 740g and i want to add in some cobra 2204 1960kv beasts. As heavy as it is it has some real punch but even my 2200mah battery that is rated for something like 130a discharge is landing warm:eek:

I have moved to a new pid controller in clean flight now and it feels so nice, it is pidc 2 luxfloat, the quad feel so connected on every axis, i have a quick vid of my tuning attempt on pidc 5 but the quad feels so sloppy and you can see it doesn't look right, pitching its nose with out any input and drifting off axis a lot. I do get some nose scraping on the grass at pretty hairy speed which i was pleased with. Ill upload shortly.


Pid controller 5, sloppy and being pushed around by the wind.

Ur Round Next - great machine. Is/was on my want list, but with the Phantom 3 very similar I might go for that, when I can afford it.

Also Im missing out on flying my Vision, the weather is great but the K-Index is very high. I know some people say dont worry, but I do :)
