Hey guys,
I was just wondering if the labels on the motors throws the balance off.
The other day, I installed Graupner E_Props, and removed the labels from the motors.

What a big difference it made ! I couldn't believe how smooth and quiet the Phantom was afterwards.
I should have done one thing at a time, to test, but it made sense that a label that doesn't encompass the entire circumference
would effect balance.

Eventually, I would like to set up a motor testing station with a laser pointer to balance them properly .
Any input on setups you guys use would be appreciated.
 
well, I imagine that the graupners made 99.9% of the difference.

But yes,. since the sticker only encompasses a portion of the motor, it has a minute influence on the motor balance.
tho so little it probably doesn't really make a visibly discernible difference..
..but i can't hurt!! so may as well remove 'em! (I did) :lol:
