I'm wondering if I need a prop balancer. I've got some vibration. I see lots of threads with prop discussions but it's always subjective. Seems if you don't have a prop out of balance, you don't need one (duh)....but we don't really know how often people actually find their props "out-of-balance". Usually in most threads they just say something like "I use mine"...or something like that. Maybe a poll can help give a more objective answer? Maybe. I know it's not perfect, but it could reveal some interesting info. I do hope you'll participate. So please choose three of the following (one from each group) and let's see if raw data can help. Please only vote if you currently have a balancer or had a prop balancer at one time and please remember this only is for your use of a balancer for your Phantom or other UAV (drone) Choices in group A identify which balancer you have now or have used (choose one) Choices in group B identify how much experience you have using a balancer (choose one) Choices in group C identify how many times you've found out of balance props (choose one) If you have more than one balancer, please just select the one you use most etc.
