X650 V4 MT3506 Funfly 18A 13x4.7 prop. YS-X6, 3S

If you try to lift off slowly if may flip.
You have to lift off quick.
Slowly raising the throttle will do this

ys X6 problem (2 min 51 sec)

Note I have scrapped this frame due to vibration issues.

I can have a look at you hj file too.
Please post a picture of your system and a video.
This will help a lot with troubleshooting.

i think some quantity produced with some hardware problems, recently this problem can be meet very often .

Agree, mine is flipping very easily in take off in man mode 1, and i always do fast climb to the air. When it's in the air it flies fine. Actually i take off always in gps or atti mode 2 as problem for me is only at mode 1, and my copter is balanced as perfectly it's possible. I think it is a kind of bug and should be listed to bug-list too.

Yes i know and i'm confused how you do it.

I 1st give a bit of throttle to see which way it is going to tip, and then as I take off I adjust and get it into the air quickly. Difficult to explain, but I have used this method on all the FC's I have flown, as they all tend to tip one way or another, until you get it off the ground. I just think it is too slow in the other 2 modes, as the motors rev up.

When I start up, first time for the day, I'll take off in manual mode 1. It feels slow to respond to stick, so I throttle hard then flick over to gps auto hover mode before nearly stacking it. It's as if it's a bug. If i land, start over in mode 1, works perfectly. Perhaps I need to go into gps hover mode first before taking off in mode 1

Live in northern ,
what is your frame ? 650V4 too ? and what motors and props using ?

My RC (Futaba 12FG) seems to be very touchy now in particular left or right. I only need to just about touch the stick and the aircraft will go in the correct direction...but at what speed. Consequently when the stick is released the aircraft will continue in the chosen direction for just a little longer before it settles down to a halt. The control does not seem to be as nice and smooth to operate as it was before a recent crash/rebuild. I guess I have done/set-up something incorrectly but I cannot see what it could be at this time...anyone got any ideas ?

Regards

David.

I saw in some post they set the esc to start up as 'hard' and not 'soft', maybe that will help someways.

Hi guys, the latest FW and GCS updates are normally posted here http://www.rcgroups.com/forums/showthread.php?t=1697842 and here http://www.zerouav.net/kefu.aspx. I do see that on their Chinese site they have a later version, and in English, but that site is geared for their Chinese market and the FW and GCS is different, so I would wait until they post a version on the two sites mentioned.

I have sent them an email asking what is happening.
