Nice Review

#5 jfdpl686 Sep 14, 2012 01:03 AM

how does the trim system work? I see 4/20 but I don't get it. My LB has left drift and I ended correcting it with subtrim, so got me trying to find explain information about the trim... can you explain me the trim setting? Thank you.

For a 3 or 6 axis gyro you are not suppose to use any subtrim or trim from what I have read.
Some people do though and it seems to be OK.

I don't know how the trim system works, good question.
They show it in the PDF owners manual on page 19 but don't explain in detail how it works. See picture in thumbnail.

Isn't it something? I've been researching about the trims. When you set it to 0/20 then the mechanical trim don't work. My theory is that the value given is the number of steps each time you move the trim, so if you move it once to the right, then your trim is 4, twice is 8 while if you set 1/20, then your trim advance one at a time. Like the Tunirgy 9x.

I will research more.

I used the subtrim in my LB and now I get it to hover almost perfect, but if it's not advisable, I will remove it.

I'm new at this and now following all your gides, I have the V911, LB and my challenge is the mini cp which I just finish setting and have to try.

I really appreciate all your post helping people learning like myself.

A big thank you to you!

Tom, can you check one thing on your Devo 10. Set the sensor voltage alarm on the 2nd sensor (main flight battery) and fly the LB and the Hoten with 3 packs back to back (i.e. without turning off the TX). On mine, the alert kicks in very early (at about 3.9, 3.8V even when it's set at 3.5).

If I then turn off the TX and rebind it runs as I would expect.

It looks like there may still be some bugs in the Devo telemetry code - would be great if you could make a second opinion.

Your welcome.

It is, I have been searching around also and can't find anything.
If I find something I will let you know.
Your theory sounds like that is what the trim system does.

If your LB is working well with subtrim I would use it.
The general rule for a 3 or 6 axis gyro is not to use any subtrim or trim
but I see many people using it without any issues. I have tried it also
and it worked fine.

I would check for you but I only have one battery for the Hoten X.
Also I have different settings for the Ladybird and Hoten X so I would have to re-bind to fly each one.
I have my sensor voltage alarm on the 2nd sensor set at 3.5V also.

I just had a thought... maybe it's not the sensor but the countdown timer which is buzzing!
Of course when you're looking at sensor view you can't see the timer... I bet it's that!!
Same buzz of course so hard to know!

I just found this. It explains what trim system does.
Also see my post #9 above.

That sounds like it. They should have made two different tones so you can tell
which one is which. When I was flying I was thinking how can I tell the
countdown timer alarm from the sensor voltage alarm. I have both of them on.
You have the sensor view on so you can't see the main screen to see the timer.

Thank you Tom, It looks similar than the explanation of the Devo 10. Not really indicating that those numbers are "steps". I had terrible times understanding the manual and ended up writing one to help me.
