    A2 vertical speed limit - I only get 4 m/s - why?

    I will assume you are not flying a DJI Multirotor...... Are your ESCs matched to your battery voltage and your motors? Did you cofigure each ESC for the full speed range while connected to each motor?

    What will happen in 2015? Make Your Prediction!

    While unlikely to happen in 2015 I am hoping that, someday, manned helicopters over cities are banned and replaced with small UAVs, with the exception of those required to transport passengers and/or heavy payloads. Not only would this be more energy efficient but, in the event of flight...

    Implementation of V2V for swarm flying.

    8 + sbus?

    Never mind..... I was thinking of a different Futaba s.bus receiver that has less channels.

    WKM M Altitude problems

    Sounds good...... whereas there are some nice new features in 5.26 I only tried it on a build for a friend and for some reason the MR immediately crashed so I lost faith. As I mentioned before I had great success with 5.20 but then sold my MR.

    WKM M Altitude problems

    Lots of reported issues with firmware 5.26....... You won't find many, if any, complaints about fw 5.20. In my case I flew my hex for over 150 flights w/o incident, then sold it and the buyer completed over 100 flights w/o incident. May I suggest you roll it back to 5.20 and try again.

    Rotor DR1 - The Drone Mini Series.

    We all need one of the power cells that indicates a capacity 2335%........as appears in the series.

    Air Ambulance Service via Multirotor!

    What do others on this forum think of this concept? IMHO - At this time a remote landing even with waypoint would most likely result in a crash and there is the risk of hitting someone at the landing area. But it might still be possible to remotely lower and release the AED at the target location.

    Large frame ESC placement

    Yes.... seen much of your coax work before from Austria including GPS waypoint missions etc. Are you aiming for super long flight time or designing for heavy payloads?

    Gimbal problem

    That link is for a 3 axis BGC....... yours is a the more limited but easier to configure 2 axis BGC for pitch and roll but no yaw rotation camera motor. You rotate your MR for camera panning. Your product seller is responsible for providing as an absolute minimum at least all required...

    Large frame ESC placement

    Yes a production fault IMHO. I had one of my Turnigy 45 amp OPT ESCs fry the first time I powered it up for the intial bench test...... (that was one in approximately 20 that I have used over the past couple of years). I always test new electronic components as soon as they arrive...

    Gimbal problem

    Your BGC system is not revealed in your posting but could be buried somewhere in the product website and/or support documentation. If your camera is perfectly balanced on both pitch and roll axis and the power supply to the BGC is fully charged then the only remaining possibility is that it...

    Horrendous flight time!!

    Yes.... but as indicated by Rotorfreek....... a bit large for smaller MRs.

    Horrendous flight time!!

    These are all slightly larger than the 5.5 bullet which further reduces v-drop risk across battery connectors and there is no effective way to measure the inflight v-drop across battery terminals. Some of the manufacturers of larger capacity batteries are now selling them complete with a...

    Horrendous flight time!!

    If you are going to the trouble of changing out battery connectors, you might want to consider the new non-sparking connectors. A resistive voltage drop at the battery connector can also wreak havoc with MR flight reliability since it acts as a voltage divider especially at higher current...
