    Pixhawk flight modes

    Not that long ago I flew a lot of giant scale fixed wing 3D. One often uses several rate and mode switches on a transmitter for that kind of flying. A friend of mine always liked to have me try out his planes. Unfortunately he preferred having an engine kill switch to shut down the engine...

    Why aren't there any smaller X8s?

    Since I am not an engineer of any sort I have to pose questions instead of providing empirical data. What I found was the X8 was more stable in any amount of wind, and could fly stably in more wind than the quad. The two frames are only about 10mm different in size. Using the same equipment...

    Why am I running HOT?!?!

    That Vulcan plate soldering is a cast iron beatch! I did one too and they are difficult to do get a good bond at one point without disturbing the bond at another point. PDB designs are something that could really be improved upon to minimize or eliminate soldering. There is no need for them...

    Pixhawk flight modes

    I don't know why but I try to always arm, take off and land in Stabilize mode unless I'm doing an RTL recovery. I do those at times just to see how accurate the GPS positioning is for the day. I learned the hard way not to take off in a Loiter type of mode, basically landing once in Loiter and...

    Pixhawk flight modes

    Since I don't completely trust any flight controller, when using Pixhawk, or any other FC, I set GeoFence or equivalent for any flight to be the maximum distance I feel up to walking to recover an aircraft, which isn't very far. Doesn't matter if it's a first flight or the 100th flight. The...

    Tarot 680 or 810

    6188g with 2 Tattu, 6s 6200ma flight batteries. 6264g with a single MaxAmps 6s 12000XL 100C battery. 5313g with one Tattu 6s, 7000ma flight battery. The 7000ma battery weighs the same (875g) as the 6200ma. Go figure.

    Why am I running HOT?!?!

    You should be able to use the 12" props with no problems. My initial thoughts are the ESC's are not what they are cracked up to be. Barring that, look at all the wire connections and wire sizes and assure everything is right with those. Might try changing out the XT60 connectors for EC-5 at...

    3DR Sight Gimbal for SOLO arrives at Bestbuy.com

    Bart, You last paragraph very strongly describes what happens when tech companies, heavily populated with young engineers, lack the ability to have vision beyond pure numbers. What you end up with is engineers trying to build a product for themselves, using the language they typically speak...

    3DR Sight Gimbal for SOLO arrives at Bestbuy.com

    I completely agree. They have some incredible products and services in the development pipeline. Hopefully the early Solo situation will not be a lasting concern.

    Why aren't there any smaller X8s?

    The 3DR X-8 has worked flawlessly for me for well over a year at a size of ~530mm. No vibration issues for gimbal served video at all. Flight time between the X-8 and the similarly sized 3DR quad is roughly the same with the battery sizes called for. Both can lift well over 800 grams of...

    coaxial different motors top and bottom

    With the FC working off of gyros and accelerometers it should not matter if the motors are matched or not. The FC will increase or decrease current based on what the the aircraft is doing. I'm with Bart in thinking it would be worth trying on a test frame, tethered of course. It could turn...

    Tarot 680 with Pixhawk

    I am so glad to hear you say that:) After all you've been though I can think of nobody more deserving of a smooth and event free flight.

    Tarot 680 or 810

    I get ~15+ minutes using Sunnysky 380kv motors, 40a ESC's, Vector, and some real bottom dollar Foxtech 15x5.5 carbon props, dual Tattu 6s 6200's, a bunch of FPV stuff and ballast in the gimbal at the moment. I have a Sony a6000 that will be going in the Arris as soon as I complete all the...

    3DR Sight Gimbal for SOLO arrives at Bestbuy.com

    I very much agree with you. Most buying a "consumer drone" (I REALLY hate that term) do so for "a quick fix". Cable Cam and selfies distinguished the Solo from the Phantom for most of those people and some of them really think that kind of aerial imagery is the hot ticket. Many limit...

    3DR Sight Gimbal for SOLO arrives at Bestbuy.com

    Over at that "other" site there is a massive level of attacks/slurs, slanders, and disparagement being made against the Solo, 3DR, and the users by people that appear associated at various levels with DJI. It's absolutely vicious. Most of it appears to revolve around newbie errors with new...

    Tarot 680 or 810

    Sorry, I can see how that could be confusing. So yes, using 15" props on the standard length 810 arms and frame plates, using the kit provided mounts and positioning the arms on the frame as the "instructions" call out leaves just about an inch of clearance between 15" prop tips. The props I'm...

    Tarot 680 or 810

    I have an 810 and the motor/ESC mounts are indeed aluminum. The frame is quite rigid using 25mm booms. It's a good gimbal platform but you have to plan your lower plate(s) to accommodate the selected gimbal, and batteries. You may want to purchase an additional lower plate. I think you could...
