I've assembled it already. Well, there is a plastic part with tiny teeth and metal spring over it. I could remove those teeth by using a file, but would like to avoid irreversible actions

I assume, one needs fancier Futaba model which supports telemetry. I've ordered also iOSD mini, going to perform some research as Motopreserve suggested. Writing down voltage under the load, after landing and consumed mAh upon recharging. After getting enough data points, i'll be able to make...

OK, apparently FrSky taranis is a popular thing here. I was a bit scared with its suspiciously low price, therefore went for futaba. Here is a link to another thread, iOSD vs mini http://multirotorforums.com/threads/dji-iosd-mini-vs-mark-ii.16564/

Opened it. Removing the ratchet turns throttle into the same kind of centered sticks, like 3 others. And removing the spring just make it freely floating - certainly something I don't want to experience. I think I'll wait a week for rails and batteries mounts and check again

Do you land at 3.7v/cell measured UNDER LOAD or on the ground? I'm thinking about DJI iOSD mini, don't see reasons to buy the full one for triple price. There was also a link to mAh meter earlier in this thread, but I don't quite understand how to read it during flight

Well, on Futaba 8J throttle joystick moves in tiny steps, compared to continiuos movements of 3 others. There is a kind of ratchet mechanism inside. So, I'm landing it by moving just one tiny step down from hovering throttle. Let's see, trying to find now any shops in Europe who sell those...

Am I missing something? Ecalc gives value about 60% only, not 80

Well, so far I assume that the biggest problem is the pilot. First flip happened when I was landing with some horizontal speed due to wind gust. Second one - when one leg went on the trail and one on the grass. But even during successful landings MR stability doesn't look so great, it rocks and...

I'm landing it with a minimum speed I can get in GPS or ATTI mode. Throttle moves usually in a little steps due to a ratchet on the joystick. I use just one step down from howering mode, so I couldn't do it slower. Yep, ordering now rails and mounts, will re-build the MR I've tried it as...

Regarding the throttle. While it is still on, even under 50% in Atti/GPS mode, copter still maintains its levelled position. So, can my flipping be caused by too fast throttle cutting down after touching the ground? (So, there is nothing to compensate any momentum flipping the machine)

Hi I have quite a wrong choice for beginner, but nevertheless.. Recently built tarot T810 for aerial photo, AUW 5.6-6.0 kg, this building log http://multirotorforums.com/threads/tarot-t810-build-log.24116/ Common problem that upon landing it tend to fall on the side or even flip, which can lead...

Flipped again during landing, fortunately on the grass, without damage. What am I doing wrong?!!

One more unclear thing I'm using Walkera Tx 5804 25mW video transmitter and Walkera Devo F4 as cameraman monitor/camera control. They are equipped with Boscam Cloud Spirit antennas. Video quality is, well.. far from optimal, let's say. For the pilot, I'm using FlySight Black Pearl RC801 monitor...

One more question. I configured my Futaba T8J according to this video How necessary is keeping one channel reserved to gains adjustment? Should I do it just ones and then use this channel for smth else? Or should I adjust gains every time when I change loading?

What is too hard? 3.3 V/cell? iOSD is on shopping list for future No, I have a direct 22V input from the power distribution board to PMU I was considering the same option, just want to check that I'm not too paranoidal :)

Sounds like a better idea, compared to removing batteries, recharging them and reading amount of mAh loaded from the charger screen. Thanks

Got my first accident, fortunately minor. At the last moment of landing, when landing gear just touched the ground, strong gust of wind flipped the machine with props still rotating. How sensitive are carbon props to scratches? Should I replace these two:

As I mentioned above, my setup is clearly overweighted (related to motors). Nevertheless, so far I got 8+ min flying time draining 2x3.6 A*h (out of 2x6 A*h) with 1.5 kg additional weight (total weight 6.5 kg)

Eskil23. I've ordered voltage meter with beeper, so I can check voltage during flight, then land and check again. Will take a while to collect enough of data points, but I'll manage. Just wonder what could be reasonable limits?

Thanks :) Yes, I'm going to do carefully research on that. Just wonder is it possible to get to the situation, when: A*h from battery are not fully consumed yet, but voltage drops below acceptable due to high load? And what ACTUALLY happens when Naza detects 2nd alarm level? Does it decrease...
