Hi
Arducopter has Autotrim feature which allows to reduce drift in one direction.
my drone drifts to the forward-right, in Althold and other flight modes, so this feature would be useful to fix this, but the wiki mentions using stabilize mode and I am not a good pilot in stabilize so is it possible to keep vehicle in althold mode and then do right rudder for the 15-20 second duration to engage autotrim in althold?
The wiki also says for most users this procedure is not necessary. I would say all users. Perform a proper accel calibration.
Read this long boring post. Autotrim is a waste of time
Accel calibration is good but I guess the f450 is not the best frame and there might be some mounting offsets.
I fly the quad almost daily so hovering the quad in one place for a single flight to signficantly reduce drift would not be too bad.
If it doesnt work out well I can easily revert back using my backup params or just by redoing this calibration
If it works in althold I am willing to do one flight to fix this
This feature has been around for a decade but had fallen by the wayside years ago with no mention of it until recently. I remember trying it out and concluding trimming for a fleeting local condition was not worth the battery/flight time.
Use the sticks…
Ok
So I will try trimming with rc if it helps
I might compare it with the autotrim and will tell the results
Don’t use the RC trims. Because if you use any other mode like loiter the trim will still be there and the drone will start flying in that direction.
If it’s Alt hold and stabilized mode, then it’s probably just wind. Fly it. That’s the fun part.
If it’s Alt hold and Loiter then there’s a set up issue. Likely there is trim already in the RC or the RC calibration isn’t correct.
I fly in an indoors and enclosed area and hence it is an issue with the drone. This drift is not there in LOITER since the gps corrects ir
Using the sticks is what I do but sometimes I look down on the rc to see battery voltage and before I know the drone has crashed into a wall
At the time I learnt to fly my first RC-helicopters no electronic tools was available to stabilize the helicopter. So changing the view away from the helicoter was the at that time very expensive death of the helicopter. There is no need to check the battery voltage, fly always with 100 % charged battery and start a acoustic timer when you arm your drone. Set the alarm conservative so to use maximum 60-70% of your flight time. So than you have enough power to land safely
Or just use a radio that supports telemetry and can warn you that the voltage is low.
Hm, maybe he has telemetry on his radio but only on the display 
and not acoustic
Which reminds me that I should to add acoustic “rotor RPM low” warning to to my radio 
.
Flysky i6x in which even having telemetry is a miracle
Have to say autotrim has worked pretty well for me for indoor use case like yours. I guess it especially comes in handy when you can’t really calibrate the level correctly like in my case where I don’t have landing legs and the drone rests on it’s Li-ion battery pack (yeah this is a bad idea but before tuning I had taped a spongy material underneath to absorb impacts from some crash landings)
Which flight mode did you use?
Main issue is that I can’t fly well in stabilize and the wiki doesn’t mention the flight modes it can be used in
I tested both stabilize and alt hold. For some reason, it worked better in stabilize - like near perfect hover, but also sort of works in alt hold.
Thank you
I will try to test this asap
I also initially had problems with stabilize but after tuning, the copter performs well. Another piece of advice for flight that I can give you is to use two fingers on each stick. It’s like unlocking a new level of fine motor skills lol.
Saw many fpv pilots on youtube using two fingers
Didnt think it improved performance but I guess I gotta try
