Yesterday mornings flight resulted in me getting mooned while FPV. This is a cropped image, I was a good 20m from them...

I was maybe 1/4 of a mile away in a hidden car park, so the shock of seeing the Phantom must have caused this reaction. :)

Not Hengistbury Head is it?

Why did he keep accelerating after crashing? Didnt think that was a good idea

I do that too, and cutting throttle completely when just a little just a little blip would have got me out of trouble, especially so when FPVing. I reckon half the props I've broken have been down to spazing out then it goes pear shaped:(
 
Few photos from today, My poor Phantom looked like a toy. S800 with gimbal, retracts, ground station and NEX5. F550.. , Some 6.8KG homebuild ....the sound larger UAVs make is crazy.

The guy in Yellow vest had just finished BNUC-S, so had flight manual, cones to keep people away and had notified Bournemouth ATC of the flight :). Even with the sign people still came over :(

Hi all,

I am thinking of raiding my DHI Phantom v1 (Naza-m 1) and transplanting everything into a F550.

What do I need to do ? Obiviously I will be using 6 rotors now, will be using stock phantom remote control, so just using the phantom receiver, will be transplanting the status LED but NOT the 'directional under arm' LED lights (want to save every ounce)

Any advice, most appreciated :)

Wanting to do it as the phantom carries my go pro and gimbal, as well as GPS tracker and a water bouy.......it flys for 5-6 mintues so im heavy weighted, a couple more rotas and a 4S battery would balance it nicely IMO.

Thanks :)

Will be using new:

- 1 x DJI F550 Quadcopter Frame
- 6 x 30A OPTO ESC
- 6 x 2212 Motor

and just using the current 9" carbon fibre blades I already have.

Anything i'm missing here or will need to fly the coptor?

Any word on this fellas?

Nice Flukester. Did the guy say what the BNUC-S was like? I've got my course in 2 weeks.

Hiya

He said the actual course was quite easy. Just fly around a bit and demonstrate failsafe RTH. The actual flying test was all in GPS mode. I think much of the exam a lot of stuff he swotted up on wasn't used like navigation etc.

The hardest part he said was the flight manual that he spent months getting together. I don't know how much work that was... I guess it varys depending on how good you are with things like that. They do provide a template flight manual on request. (which he only found out after making his own)

Every flight he makes though all has to be logged, and at all times has to show in his actions that they are safe, hence the cones / signs and call to local ATC.

The S800 though was amazing, I hate to think how much it cost, even the gimbal was double the cost of my entire Phantom setup. Almost felt my Phantom had no place there... but like he said with a gimbal the Phantom is easier to deploy fast.. the S800 took ages to setup.
 
I notice that it's possible for a Quadcopter to fly with a failed motor but take it DJI don't implement this algorithm, looking at videos on YouTube. Any chance of them doing so in the future?

Also, I'm looking to get a video switcher and a new controller now (FrSky Taranis) for my P2. Do I need to install a new Rx or would the Taranis pair up with the stock Rx and allow me to control other stuff OK? I'm quite happy digging about and cabling stuff up now. :D

BTW FPV is much more fun with the new camera - stunning picture quality for the resolution. :D

Maidened the S800 EVO yesterday



Pano shot from the Nex5

S800 Panorama by Rilot, on Flickr

I was testing the FAS-100 current sensor and it's pretty accurate. I flew for 8:30 and according to the sensor used 6580mAh of juice. When I charged the LiPos I put back 6610mAh. I'm flying with 2 x 6000mAh packs so flight time of 12 to 14 minutes is where I'll be. I didn;t want to fly to 80% on the first few flights as I wasn't sure about the accuracy of either the FAS-100 or the iOSD voltage monitor. Now I'm happy with them I'll fly to 80% next time.

What camera and mode are you using to produce the panoramas?
Click to expand...

Camera:

Sony Nex5 - Sony 16-50mm f/3.5-5.0 PZ lens
Mounted on a modified X-Cam X140bs gimbal
Shot in manual mode (shutter @ 1/100 and aperture @ f/8) but I messed up the metering which is why the sky is washed out. Next time I think I'll shoot in aperture priority mode
I take a shot, rotate the craft, take another shot, rotate the craft etc. then stitch together in Photoshop CC

Gimbal ordered today for Phantom, a whole £47 from China, gets good reviews also.

I'm still not able to justify the cost of an H3-2D, especially with the H3-3D around the corner. I'm tempted to try a different gimbal but a bit put off by them not necessarily being plug and play...

Would that gimbal you posted work with a P2? How would you mount it and how would you power it? Looks like it wants a 3S feed? Also, can you control the tilt with the remote?

I have one of them Flukester. It works really well for the money but I had an issue with horizon drift and eventually replaced it with an H3-2D as I preferred the way it integrated with the Phantom.

Ahh cool, glad it's ok... for that kind of money it's not bad I guess. I'm going to try and lighten the Phantom, trying to save the expense of a Phantom 2 :)

If you want contact of a guy with same setup as you whos done BNUC-S just shout, he's a fountain of knowledge :)


edit: what do you mean by horizontal drift ?
