    Tiger-Motors U8 + 28x9,2 props

    @srbell, Yes, this is the Riegl Frame. @Waladi It will be flown with 8S50000 up to 8S100000 (so 1,4 - 2,8 kWh on board). If you fly at high altitude you can switch to 10S or 12S. Actually I do not know how these square tubes are manufactured, I only know that these tubes have been made for...

    JR Ninja X? Looks like a Variable Pitch HL Quad?

    If propellers have different angle of attack they produce different torque on the frame -> yaw.

    How Do We Fix Stupid?

    All you do is, you draw the attention of people to these videos, whatever you think of them, there will be others inspired by them and new videos will come (just because you watches, discussed and shared one of these videos). DO NOT WATCH, SHARE, QUOTE, DISCUSS,... SUCH VIDEOS. If there is no...

    DJI Inspire 1, What's the Verdict?

    This is described in the release notes of the last FW update. If you are within 20m of the RTH-destination, it will just land and not do RTH best regards Ferdinand

    DJI Inspire 1, What's the Verdict?

    I am using a Gigaset QV1030, but it is too big to fit, which I solved by modifying the tab-holder. best regards Ferdinand

    DJI Inspire 1, What's the Verdict?

    At my tab this is just a setting ... You have to connect the tab (with the wire) after starting the RC-TX, otherwise it won´t connect. The IOS support is as it is, but it is not official so far, but there are updates (inofficial ones). I don´t think you need a tab at all, but I have not tried...

    DJI Inspire 1, What's the Verdict?

    @Quinton, You have to activate USB-debugging on the Andriods. Also you can enable/disable OSD on the HDMI-out best regards Ferdinand

    DJI Inspire 1, What's the Verdict?

    @Quinton, There is something wrong with your battery, you will have to contact your dealer/support. Really sorry to read that. And yes what I use is a power supply where you can adjust the voltage and limit the current. If you recharge with the charger it comes with it is about 75min, with...

    DJI Inspire 1, What's the Verdict?

    If the voltage is too low, the battery will not get full, if the voltage is too high the battery will burn. Also charger use CCCV (Constant Current and if the target voltage is reached Constant Coltage), you just the the voltage via selecting the number of cells. This battery has just a sightly...

    DJI Inspire 1, What's the Verdict?

    The connector is the one the battery comes with, there is a extra wire that comes with the Inspire which is meant to charge the RC-TX from the Battery, so I just cut this one. The "charger" that comes with the Inspire outputs the 26,3V (which is 4,383V a cell) so it is natural to use that...

    DJI Inspire 1, What's the Verdict?

    You can reload them with a powersupply where you can adjust voltage an limit current. DJI says 120W ist the limit that is about 7A, here it takes about 45min. But you need to be precise about the voltage (26,3V) best regards Ferdinand

    DJI Inspire 1, What's the Verdict?

    I´ve build really a lot of copter until now (from 10" to 30" propeller), but the Inspire is somewhat relaxing. Take it out of the box, nothing to tinker just flying, battery recharging and flying again. What time you spend in video-edition is up to you. I had to balance my cam (needed 2...

    What will happen in 2015? Make Your Prediction!

    I would watch out for larks and wasps :D However, this is about predictions, if you predict something almost clear, people will say, "well, that was easy, or they will even not remember, ...", but if you predict something completely crazy, completly unthinkable, and this comes true, people will...

    What will happen in 2015? Make Your Prediction!

    Europe will enter a period of deflation, US will follow. Greece and Spain (not Italy) will leave the EUR, Oil will be back to < 30$ a barrel. Markets (dow, dax, ...) will crash to unthinkable lows dow < 5000, dax < 2500. ok, you mean precictions on multicopter ... people will continue to fly...

    Large frame ESC placement

    I am just experimenting, sometime flighttime, sometimes payload and sometimes both is the result. But typically the aim is to carry some payload for some distance and some time. The more one of the numbers grow the more difficult it becomes. So to drop an number, 30min with 8kg payload and...

    Large frame ESC placement

    Copter big enough? All of my copter are build with ESC on the booms some of them are really big. Never had a problem (that does not imply that anybody else will be safe). Big copter are big because of the propellers used, if the layout is somehow correct the bigger the copter the more...

    Ideas for this year's Group Build?

    If you do a 10" (propeller) setup you can do an "allinwonder", basic fpv-quad, basic quad for AV with GoPro, and a racing quad Of course I like the 80tons carrier most, but I would call it "80tons medical asisstence carrier". best regards Ferdinand
