  • Bad Raven: I think a lot of us will have seen the published (leaked) training instructions to police officers on FPV, which was both incomplete and incorrect. Only the Little Hitler types will be comfortable treading any of that path!

  • Reman: Thought for the day - If a knowledgeable police officer stopped you and saw that you had a "600mW" VTX on your quad he'll get funny about it, But would even a VERY knowledgeable officer know what they were looking at if the same VTX had a professional looking label under the heat shrink that proclaimed that the VTX was in fact a 25mW unit?  :hmm:

Micro gradually self levels ( pitch ) in acro mode
« on: October 04, 2018, 19:18:41 »
Hi
Am somewhat new to betaflight.
Have a slight problem , as per title.
Seems to be in pitch mostly , is slower than angle mode self level .
Model is a stock snapper 7 , with crazybee fc, 703 brushless motors , on dsmx.
Laptop has betaflight 10.4.0. Shows firmware BTFL 3.5.0 , target CBFR , and cpu load 34%.
Things I've tried ;
Switch off accelerometer.
Put acro (nowt) / angle / horizon on a switch and enabled show-mode on osd.
Upping I term drastically  (110) then also P & D terms.
Google.

Strange thing is that my tiny whoop ( brushed ) from about 2 years ago ( on cleanflight ) had the same issue ! The only notes I have from it are the pids which were high ( I term at 110 ) , and I absolutely can't remember how I solved the issue / was it that high I term ?
Must have been a fairly simple fix for me to have found it.
Any advice gratefully received.

Typically, although it feels like it is levelling, what is actually happening is the quad is very slowly pitching back, this is generally because the fc is reading the tx signal on pitch as being off.

Recalibrate your radio, then, props off. Power up while connected to configurator, and the radio on, go to the receiver tab, check what mid throttle on pitch (and whilst you are there, roll and yaw) reads, they should stay on 1500, if not adjust the sub trim on the radio so they are. If they move about a bit, add enough deadband to cover it

Well that sorted it !
Many many thanks.
An easy to follow solution , and you even managed to describe the symptom/ problem better than me.
