@sloscotty, i think with "betaflight attached" he meant the configurator. From what i understand he already runs betaflight on that FC.

Ahh...OK, I misunderstood.

Actually arming the craft and using the live flight controller to control things will do all kinds of strange things if the craft is tethered.

Thanks Unseen. I had rather suspected that.

(21-May-2017, 05:46 PM)fftunes Wrote: Yes. When pinned to the ground, the slightest bit of noise (or rc command jitter) can/will add up to some error eventually, to which it will react by lowering certain motors when you are commanding full throttle. And since it can't correct that error, those "correction calls" will become stronger and stronger. If the quad was in the air, you could expect all motors to run at pretty much equal rpm readings.

As unseen said, to test motors, one way would be running the motors from motors tab in the configurator without arming from tx - this would prevent the PID from becoming active and commanding motors down (or up if not at full throttle).

Another way would be, to use tx to command throttle but set all PID to ZERO so they have no effect at all, in order to allow all motors to go full throttle. You can use a second profile in betaflight to not erase your previous settings (in PID tab of the configurator).

Thanks FF, that is a good tip.

As far as I know the centers were all set at 1500 during the initial set-up but that is not to say I have not accidentally moved theTX trim at some point since. I will recheck those later today.

I am familiar with the 3 profiles however what I would like to know can these be selected by using a TX switch? I know you can change them in flight with stick commands but I would prefer switch control. I do not think I have ever seen a reference to controlling profiles via a switch.

Once again everybody thanks for your help. I really do appreciate it.

Regards,

KK

(Unfortunately, I can't help him much with Hero questions like "how to zero heading".)

Slo the full title of the Hero is such a mouthful that I can never remember it but here it is as copied from the MultiWiiCopter web page;

[b]PARIS Sirius™Air HERO•32 r2 BetaFlight BorisB - Sbus - METAL case - Controller Naze32

I do not have the GPS module unless it is built into the Hero which I doubt.

FF, yes I did mean the configurature and no I will not attach it after your warning.

Wow! Was I ever off-base! Well you know what they say - when one ASSuMEs things...please forgive.

On a different note.

In the very beginning when I knew absolutely nothing about quads ( as against my current standing which is almost nothing) I purchased 
 a HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA) which was to my surprise a "+" configuration controller as against a "X" config which is what I really wanted.

Is there any way to re-program that FC to an "X" config FC?

I did fly with that FC and it really worked well but the "+" config made it really awkward to fly with.

Slo if you are worried about the bold type in the Hero posting please don't.  When I  pasted the hero title all other text after that was in bold type and try as I might I could not find the text format control.

You have nothing to cringe about,

Anyway I have already used up all of my crawl under a rock emoticons

Sadly no, you can't change profiles by switch (yet). And you can only do it while disarmed.
However, using stick commands, it's quite easy once you know, especially when you're using mode 2 transmitter, mostly every reference you find will be for mode 2. What helps is having a beeper, it will beep according to profile number that you changed to. FC LED will also blink.

You could put these stick commands on switches by simply creating mixes theoretically but it's not so practical since it would take for example 3 two-way switches... or some other way of complicated tx programming (for example 3-way switch to select mix + temporary switch to execute) but imho it's not worth it.

PS: only way i found to fix text formatting, is using "quick edit".

FF, as is my wont I always do things the hard way so as you might expect, I fly Mode 1 hence my dislike of stick commands.

I will see if I can convince myself to learn the Mode 1 stick commands.

Oh well then, yeah for mode 1 and mode 4 the profile stick commands are very uncomfortable, that's true...

I memorized the actual functions to change profiles like:
"throttle low, yaw left, and
- roll left => profile 1
- pitch forward => profile 2
- roll right => profile 3"
Just repeat saying the above to yourself until it "sticks" lol

Thanks FF however I am a bit puzzled.
They are all routine flight commands.
Is there an additional trigger command to denote you wish to change profiles or is the fact that the quad is unarmed the trigger command?
I am guessing that it is.

Yes, exactly. All the stick commands only work when the quad is disarmed.
