Top Flite Magnetic Prop Balancer from the vid:
Thanks to all of you that recommend this amazing prop balancer. This thing is magical. I was skeptical at first, but now that I've been using it I realize what I've been missing out on. My previous balancer did a so-so job, but once I threw my Graupners, APCs, and Gemfans on the magnetic balancer I was completely surprised. Not a single one of my props was perfectly balanced.
I'm getting the hang of this and still am trying to work through some hub balancing issues, but this thing is incredibly sensitive. In some cases I feel it's too sensitive :)
I promise not to bore you with too many more vibration videos as I'm almost to a place where I'm happy. I have one more coming out that is an updated vibration dampening material comparison and then I can move on to more exciting updates.
If there are any other prop balancers out there that you recommend then please post in the comments below.
