Sure. But basically, all the subjects are getting cut off.

Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

Help checking vibration graph

Hi.

I wonder if some of you could have a look at my accel graph.  I have been trying to reduce vibration on my f450 flamewheel clone in preperation for the new software when it is released.

I have mounted the apm 2.5 on 4 1cm 15mm high blocks of soft neoprene on the lower frame plate.

Are these acceptable levels of vibration whilst 2ft off the ground in a hover?




Thanks for taking the time to look.

Reading the arducopter page on logs , it says the vibration should be within +- 5
So yours look easy within that !!!!

andycap

Thanks for the reply, I was just unsure of the z axis showing -9 something on the log.

I havent had a lot of time on the forum the past couple of days but as above below plus or minus 5 is good  ~~
mine is fine a little bit over that  :beer2:

Hi Andy,
The vibes look fine,  the -9 is due to the accelerometer reading the earths constant gravitational acceleration of 9.78 m/s so -9 on the z axis is fine.





The above are from my Q650 quad running APM 2.9.1b mounted on earplugs.
Not as good as I once was, but as good once as I ever was

andycap

Thanks Tango21Delta.

I did not even think of the accel being able to pick up the earths rotational speed  :wack0 I was thinking that it was going way over the recommended value with -9 and the deviations on the graph.

I am a happy camper now.
