Lifting capacity?

Started this discussion. Last reply by Michael Pursifull Oct 12, 2011. 6 Replies

I tried to search, but are there any lifting capacity graphs (flight time and battery calculated in) for the 3DR frame with the 880Kv motors? If not, what is the lifting capacity with the 880Kv…Continue

I have a small problem with the ArduPilot when I put it in both FLY_BY_WIRE_A and FLY_BY_WIRE_B,  the rudder goes almost full to the left, not all the way but say 80%. The rudder still works both…Continue

"Ardupilot is ok with Tek Sumo wing. Just don't make that wing heavy. I've tried that, now ardupilot is on EPP FPV, and Tek Sumo is for FPV only."

"Hi Great to see some aerial video from home!! I will be home for 4 days from the 25th of march, maybe we can get some flying done together, I even have several planes laying around, you can have some of them if you want to. Kim"

The last journey of my EasyStar

I recently bought a GoPro (HD Hero2) for my EasyStar, but managed to crash it before I could mount the camera. But I just had to see the HD footage from the sky's, so I glued the EasyStar together again. I throw it in the air and immediately felt it was tail heavy and banked to the left. I trimmed it a bit and managed to fly it reasonably well, I still never got comfortable whit it. I still got some great footage from the flight for you to enjoy. Sadly this EasyStar never got to fly properly…See More

"Sure. Everything is a balancing act. If you can make that 300-40g payload lean towards the 320g side, you can get about about 50% longer flights with a 4400 mAh using the jDrones frame and the 850Kv motors, than if you go with 3DR/880/5800mAh. In…"

"But 1380gr at 100%, does that mean that I have to subtract the weight off the frame, electronics and motors from the 1380gr to get the max payload wheigt?"

Lifting capacity?

I tried to search, but are there any lifting capacity graphs (flight time and battery calculated in) for the 3DR frame with the 880Kv motors? If not, what is the lifting capacity with the 880Kv motors and a pretty much standard 3DR frame (I know a standard quad doesn't exist, but you get the point). Hope anybody knows, thanks.See More

My first "major" crash!

Posted on August 17, 2011 at 10:15am 10 Comments

I have never had a major crash (except some stupid nosedives) until today.

After the first waypoint ArduPilot suddenly decided my EasyStar was to high, and before I could recover control it disappeared behind some tress.

It was quit a loud bang when it hit, whatever it hit.

Lucky it wasn't dead, so I could track the plane from the sound of the engine.…

Replay XD1080

Posted on June 14, 2011 at 12:30pm 14 Comments

Maybe this camera I found on the web would interest fellow aerial photographers.

 

It apparently doesn't weigh more than 85g, can take up to 1080p and it looks like a easy camera to fit on a plane compared to a bit more bulky GoPro.

Fant deg her på diydrones og lurer på om du har arducopter? Jeg prøver å kartlegge antall piloter i Norge for
å skrive en artikkel om dette.

Også skal vi i løpet av året organisere en arducopter / uav dag og du er kanskje interessert?

Hei, eg har dessverre ikkje ArduCopter, men eg har planar om å skaffe meg ArduPilot forhåpentlegvis snart.

Men det høyrtest interessant ut med ein ArduCopter/UAV dag, så gje gjerne ein lyd om du veit noko meir om det.
Eg kan forresten vere behjelpelig med ei eventuell nettside for informasjon og kunngjeringar for dette formålet via firmaet mitt på www.zwarte.no. (Det utfører eg gratis isåfall.)

Ang. artikkelen din er det eit selskap i Hardanger som kan vera av interesse for deg, nemlig Panorama Hardanger. Eg er usikker på om dei brukar ArduCopter, men dei har bla. anna filma Ekstremsportveko på Voss for NRK med forskjellige UAV'ar.
Er dette ein artikkel som hamnar i norske avisar forresten?

Lykke til med artikkelen, mvh Peter-Hans de Zwarte.
