Ok I just increased the arming range. Please update the FW and try again

Also please post the pic of the GCS when your channels at 100% rate and Pitch down + Roll left. I have no serial PPM RX and need some point about its range to tune the serial PPM receiving module properly.

Yes, it works.
Channels at 100%

Thank you.

Anyway it will be safer to scale up the serial PPM channels rather than increasing the arming range. I`ll think about it later.

So I'll be waiting for your results..

It's flying.
And that not so bad.
I would say, in acro-mode the p-term is too low.
In stabilize mode it wobbels a little bit.(fast)

How can i level stabilize mode?
For me it's hard to fly a not good leveled stabilize mode.
Acro no problem, because i fly all my copters unstabelized.

And i had to reverse yaw-gyro.

what did you mean saying low? Is it sluggish and not so manoeuverable?
Assuming a little wobble in the level flight I suppose the D is too high for you. Decrease it for 20%. And increase the "RC rate" in the GCS to gain more control from the TX.

To level the stab mode just press the level button in the GCS. If your quad drifts anyway, insert something under the quad leg of that direction and press level again. Also you can use the TX trimmers in usual way.

I must test a little bit more.
Sluggish? Not really (i think).
It does not hold the direction.
But it was only a short flight.
Next tests on sunday i think.

One a clock in Omsk?
I wish you a good night.

And i go and drink beer!!

duh! I forgot that.. increase the yaw rate to 1.5 or so. The 0.5 is ideal for my tricopter with the tail servo. My friend with 800 quad was happy with 1.5.

When using LM1881 syncsep, you need to invert the hsync signal, or invert the logic in TIM9_IRQn for PE5 high/low check. Not sure if this was mentioned anywhere.

You are right.
Today i tested the OSD. But there was no OSD.
I have doublechecked the wiring. But it seems to be OK.
Then i added a 7404 and everything OK.
Thanks!!

Sorry Oleg.
No flight today. And i think the whole week.
It's raining and it's windy like mad.

GPS Works!! I've changed it to 10Hz.

Hello.

Are there any plans to support a Sonar?

And isn't it possible to create a leveling-window in GCS with level-button and simply arrow buttons to tune the stabilize mode?
Then you can do a inflight-leveling with your wife. And it's no longer boring for her.
I think it's more simple than land level land level and better than using the trimmers.
I think, if we use the trimmers the acro-mode no longer fits.

I just found better solution:

You're flying your quad in acro mode and set the trimmers to fly it as level as you wish. Then you land and press 'neutral' in the autopilot setup. That's all. In every modes your quad will be trimmed correctly. In acro mode your TX trimmers will work as usual. In stable mode the board will 'simulate' your trimmed values.

By the way, you'd better not pressing LEVEL while flying multirotors. The level calibration takes about 2 seconds and your quad may kiss the ground in no time.

I do plan to support sonars later.

FW update 2.0.1827

Implemented things described above:
Firstly takeoff in acro mode, level with the trimmers, then land and press 'neutral' button.
Also it should remove the yaw rotation speed asymmetry.

I've never thought about pressing the level buttun during flight.
But you are right. Maybe the wife.

If it's not raining this evening i will test and report.

Hey Oleg.

Do you plan to implement a LM1881-fix in the software?
Or should i solder the 7404 on the board?
I don't care.
At the moment it's a "free" wiring.

Just came out of the garden.
And i must say it's flying well in stable mode.
In acro mode the copter everytime wants to fly in one direction.
Sometimes left, sometimes forward ..... and so on.
So can't exacly tune the acro-mode to press the neutral button.
Only trimming.
Vibrations? Copter to small?

Now it's raining.

And i have a Problem with the GCS and the resolution on my 10" Netbook.
I can't see and press the buttons under the Frame Type.

Marcus

PS: I think i must open a Youtube Channel and make some Videos.
