thank you Jerry
I think someone tried a ground plane under the gps and it stopped the toilet bowl effect. A better 3d fix. Not sure who tried this.

Sorry for the late reply I missed that post.

Yes it looks OK except all the values you have as 50% (+and-) should be 100%. Each column should have a max of 100%. In the case of the X configuration the pitch motors are all the same distance from the pitch axis and the roll motors are all the same distance from the roll axis. Hence they should all be 100%.

Test it on the bench with all the props removed. Throttle up to 25% throttle and move the vehicle in each axis. You can hear individual motors speed up and slow down and it should match what you expect.

Both manuals were the same on rotation. I don't know if it could be my gps calibration or if I'm doing something wrong in the computer software.

Read them again, the motor numbers are not the same. Good luck.

I had a similar problem with the yaw or rudder in Acro Mode on TX.
Touching yaw to the left the craft accelerated a lot at same time that rotate.
Touching to the right did not accelerate... but did not rotate! I got a big crash due to that.

At the end changed to Heli Mode and all controls worked as it was supossed.

I can't remember where I read that it was necessary to be in Acro Mode but it did not worked well for me.

All of you, guys, fly in Acro Mode in your TX setting?

Can you tell what FPV gear you are using.

Fredde
gear is pretty standard fare:
gopro2 hooked up to 900mhz video tx (really dislike the fisheye...can't wait to change that)
fatshark base goggs
sandisk dvr (better/more reliable than my aiptek)
haier 7" lcd

i don't know about the captain, but people say i make funny faces when i fly fpv (i guess that's what you call full immersion, lol)

i have gotten a few comments saying that i am brave for flying big like that, but i am not. the truth is, i have spent many, many (too many?) hours building different helicopters (starting with a traditional single rotors on glitchy 72mhz). i have made my mistakes and try to learn from them. there are no "good enough" solder joints or wire routing on this build. it is a pain in the ass and i have to force myself to take my time, even do things twice, three times, but i cannot have any doubts when i put this kind of multi in the air. sure, i will throw together a quad for some park flying or to try the FC of the week, but before even contemplating a flight like this, i logged over 50 problem free flights (meaning zero issues, zero crashes, zero w t f's?) and made notes and recorded milestones. i could have gone another 1/2 mile out safely because i had already achieved a 3/4 mile flight. you will notice my flight is just over 3 minutes. i could have loitered around the ship for another 2 minutes safely and still have enough reserve to come home. but i felt i got the footage i needed and yes, there is still pucker factor. if there wasn't, it wouldn't be an adrenaline rush.

so, when i was trolling around the city on my day off and saw that ship in dry dock, i just imagined my field over the water in front of me, knew my Y6 was flight worthy, and i said, "yeah, i can do that."

How many guys here are using the voltage failsafe for the Wookong? I have not been using it but might start -

I don't because I don't trust their BEC... but you can remove the red wire and use it as voltage sensing only...

it's working well on my naza but I had to fudge the number so they worked with real numbers I was getting from my telemetry...

I have it set to the LED flashes when I have about one minute left then I set the auto land voltage so low that it will never kick in...

I am, and I love it. I've tweaked it to 7 minutes of flight time on a 5000MAH 4c battery. (I have a very heavy craft). Works great every time and I use about 80% of the battery.
