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.
