    SynDrones X8 Heavy Lift Build

    With your A2, what's your vertical gain setting? Too low and it may drop and climb through maneuvering... OT, good looking bird! :)

    What is actually the best Flight Controller for HL multirotors...?

    On the A2, version 2.3. I've built and delivered appx 30 machines using this without issues during test flights. WKM, version 5.26. This is also what I use on my personal machine, a 900 sized bird designed to carry a 12lb payload. It has a WKM with 900mhz datalink on it as I haven't had a...

    A2 Regret

    Are you certain you have the appropriate items plugged into can-bus 1 and can-bus 2? I had trouble initially with the GPS puck plugged into the wrong can-bus...

    A2 Dilemma

    My only loyalty is to my customers. I'm selling them a complete turnkey unit, and I use only components that I'm comfortable selling to them. After all, if their unit crashes for whatever reason, they look to me not DJI, or OS, or Exceed, or any other companies components that I use. I'm the...

    3s vs 4s with e300 hexacopter

    I fly 4s, using a 5000 mah pack, I get appx 12 minutes carrying the H3-3D, video downlink, and 2.4 Datalink on a Hexacopter with the e300 system. I tested it with 3s, and it flew, but I could tell it didn't have the power, and the flight times were horrible.. I have a buddy with the flamewheel...

    A2 Dilemma

    I'm now on a third A2 in 3 weeks on 3 different builds for three different customers, all working as advertised. All 3 units were purchased at different times over the last few months (had a 2 month hiatus while we moved our shop to a new facility). 2 were on 900mm Octocopters, the latest on a...

    Noob with unresponsive ESC's/motors using WKM

    Your throttle isn't backwards in the radio setup, is it? If looking at the slider in the assistant program, low throttle should have the slider all the way to the left.

    Question for E300 owners

    I've installed the e300 system onto my own design Hexacopter, did not worry about balancing the props. With 3ea 4s 2200 mah packs, my weight is around 2700 gr, flight time appx 15 minutes. Here's some onboard video straight from the camera. http://youtu.be/6XyGl9K8ZO4 I think the props are...

    DSLR capable multicopter around DJI Naza

    I don't think it's the weight necessarily that causes issues, it's overloading the capabilities of the airframe. For instance, here's our 900mm Hexacopter with appx 4 lbs of payload, for a total AUW of appx 15 Lbs, flying with a Naza w/GPS. Seems to work just fine...

    DJI WKM Octo problem with 5.12

    Successfully flew an octo, using traditional Rx, "I" formation, on 5.12a, on Saturday. Tested the RTH switch and IOC POI. A few gain adjustments and all worked perfectly for a flight of appx 15 minutes. I previously crashed this Octo when I allowed the batteries to run down a bit, setting...

    Pics of one of our latest Octo's with mount from Helicamsolutions.com. She weighs 14.8 Lbs with 2 ea 4s 5000 mah batteries and can carry up to an 8 lb camera. Flight time with just the 2 batteries is 10 minutes+, it is possible to add 2 or 4 more batteries for extended flight times.

    Were to find large copper washer for power distro

    Dang you guys. I thought I had an original idea with using a washer. :( I have used a large brass washer, steel washer, and copper rings made from soild copper wire, soldering 10 AWG wire to them. So far I haven't seen any issues with EMI or such.

    Has anyone tried using O.S. motors for multis?

    YES!! We are using the OS 30 Brushless motors on our line of Multi's. So far, reliability has been a non issue. We're swinging 13X6.5 props with 4s packs.

    DJI WKM yaw issues.

    Lazy ESC's or a motor with a bearing problem can certainly cause this, or other issues such as trouble holding position in one aspect such as forward or back. As a test, try swapping it with a different leg, say one that spins in the opposite direction to see if it has any effect. Then try...

    Customer's with actual truthful issues I can deal with, it's the trolls/haters/potstirrers that make it difficult. It's especially sad when some mods are the ones trolling!!
