Up for sale is the 2-AXIS Quadframe gimbal V2 (also referred to as Jakub Gimbal) . I was going to use this for mapping purposes but its more than I need. I also think my camera is too light for the vibration dampening system. The gimbal comes complete with: -- Original V2 2-axis gimbal...

The authors are not saying drones should not be used and the article I linked clearly makes this statement as well. I have now read the paper and do have some concerns about their tests. Its a good first look but I would have done some things different. I can say the same about some of my own...

Just had a colleague send me this news link today: http://www.washingtonpost.com/news/energy-environment/wp/2015/08/13/drones-could-be-stressing-out-wildlife-scientists-suggest/ and here is a link to the paper abstract: http://www.cell.com/current-biology/abstract/S0960-9822(15)00827-1 Edit...

Jakub, Very interested in the InfinityMR-S but the tray has got to be a bit wider to facilitate other small cameras like the A5100 when their side access door is open to facilitate the camera trigger and hdmi converter. On the A5100 you need just shy of 125mm of clearance (see pics) with both...

Not trying to start a fight but if your not aware that there is even the potential for pop-up thunderstorms then you haven't checked the weather well enough in my opinion. The situation is certainly a little different in coastal areas where there is always the potential, especially Florida and...

You are 100% correct! Tooting my own horn a bit, but I have had to climb into a tree and strap a piece of plywood to a branch at about 35 meters and then launch my copter from there and fly through a small gap in the canopy before getting into open sky and able to switch on the GPS. Doing the...

That's why when you go to fly a mission you have to pay attention to weather for sure. I am always checking the forecast and local conditions, and closely watching the radar. In my South American work where there is no local radar I rely on satellite imagery to make sure I don't fly into storms...

I think with Crayfellow its more so the KDE ESC setup causing issues. When I first built mine it flew fine on the first flight except for needing tuning, and that's with 2 kg of batteries on top and nothing underneath. Sure I've had a few issues with my builds here and there but mostly user...

It worked great. I just got lazy with this last one. I would rather have legos all over than my copter covered in water in case of a crash.

I've also constructed a lego container with lead fishing weights inside (built so they don't move around) as dummy weight before too!

Ok, I had interpreted previous statement as you were flying with it off. Sorry. Have you measured the gimbal setup with camera and matched the water bottle weight to that. When you get around to auto tune I would do it without the gimbal, etc. and just do it with the bottle as close to the...

I use the ones from Event38: http://www.event38.com/ProductDetails.asp?ProductCode=RFD900 much longer range than SIK style linked to by JoeBob. But jDrones also has the RFD900's. Event38 customer service is top notch!

I have had a similar problem in the past and for the life of me can't remember exactly what it was. I believe it has to do with mid-throttle calibration (parameter) and the difference in position of the throttle to that. You might need to adjust the dead band around center throttle too. I would...

Man I give you kudos for perseverance. Glad you got it going but please be careful with that spinning prop situation, maybe take some leather gloves next time. I just made a mental note - don't use kde esc's. Definitely would ask Patrick at this point.

You should be able to push them out from the top side. Just might take a little gentle work.

After it was cut in half I reused the holes on the inside (left finger in pic) and drilled new holes for the outside. Used the mushroom head style screws on the outside since the battery would be on top. Second picture I just set the broken tray on top of the screws to give you an idea of what...

Sounds like your on your way to an uneventful maiden. Hopefully!

I can verify based on my build that is very similar. Have you done the motor number test procedure from the wiki? I have made the mistake of having the wrong motor plugged into the wrong slot on the Pixhawk and it did cause it to tip. When you arm the copter the motors need to spin, you can...

I think something else may be going on that is causing the flips. I first flew my nearly identical bird with 2x 6s 8Ah Multistars on top with no payload and it popped in the air just fine on default pid's but was certainly a bit unstable. Nowhere near flipping. Make sure you've done radio...

That is pretty darn nice video! Any chance you could share details of the setup or a pic of how you use the silicone chips? What gimbal? Thanks for sharing!
