    Phantom-3 on test

    It seems to be very much better than the 2 series. The response to disturbance is really fast. I flew it yesterday in 25 m/sec wind. It needs regular calibration it seems. That could be to do with me having transported it near to metal objects in the back of my car. It took three attempts to...

    Phantom-3 on test

    @SleepyC I know where your coming from. You need a very good reason to risk a 5 kilo machine anywhere these days. Working on a music vid. with it at the moment both inside and out, also using it as a hand held steady cam. This is an awesome tool to have in the bag.

    Phantom-3 on test

    Got mine direct from DJI and it's great, Clearly they have listened to what we wanted and done a great job. This is the results from it's first two flights straight out of the box. OK the Sony 7s is better in low light and the GH-4 is a better stills camera. But this is not a 5 kilo machine and...

    Align Multicopter Align G3 tuning

    Align have also released a new APS-M signal wire set. About time too as the original ones were crap. I have now proved beyond doubt, that my recent crash was due to a faulty cable. When you peel back the rubber sleeve you will find a nice stress raiser in the form of a dollop of glue to hold...

    Align Multicopter Align G3 tuning

    Your balance may be the problem. There is a need to take up the slight movement in the side arms. Don't let them sag against the stops. What lens are you using? The secret to getting it to perform correctly is in the calibration. As a general rule I run the start up three times before it settles...

    KK Flight Controller KK2.1 Tricopter

    Dan The thing to remember is that the vane is basically not a rudder but a means to create a yaw torque rotation around the rear motor so the blade area must only be aft of the motors axis or it will just self cancel the input. i.e. one half of the blade will act in opposition to the other...

    I now have the high voltage conversion working OK. As a general comment I would say that with the 2.2 firmware the P values need to be reduced a bit from the recommended settings.

    KK Flight Controller KK2.1 Tricopter

    Hi Guys I have done some work since I posted this video and was able to get the KK board working really well. What is surprising to me is the endurance. With a standard DJI 220mah 11.1 battery I am seeing around 20 mins flight time. The model has changed slightly with a smaller vane. but...

    New control concept

    Hi Guys The trend at the moment seems to be towards radical new designs. In an attempt to revisit my interest in the tricopter idea, I dug out one of my old designs and had a rethink on how to improve the yaw function. The tricopter should in theory have better energy conversion because the more...

    I have now tried the HV adapter and found that one needs to reduce the P gain significantly. Most vibration issues that cause jellow are in fact not vibration at, all but high frequency oscillation from too much D and P gain. Anyone else found this? I would say that the Calibration algorithm...

    @Shelipso I found that the 20mm lens (Mk2) just comes within the standard adjustment range. It is a short pancake lens. I am using 8 and 10,000 mah batteries. in the standard holder. I can't wait to try this voltage booster as when I tried to use my 14-140 lens I did see a little shake. I tried...

    Guys I did the comparison between the carbon one piece supreme and found no difference at all, the folding ones work fine. You can balance the standard props with a slightly modified rotor blade balancer adapter. BTW Kite surfers in Cyprus don't fly below 20 M/sec. The 20mm lens is equivalent...

    I added a M480 to the fleet this year and was very impressed by the quality throughout. I have just upgraded to the 2.0 and 2.1 firmware for the flight controller and gimbal and can make the following comments. The stability of the model in high wind is probably the best I have ever flown. The...
