Bigger and better "Extreme accuracy Prop/Rotor balancer"

I got the "Extreme accuracy Prop/Rotor balancer" from Hobbyking but did not find it particularly accurate...

I designed this to match the part you put the prop on. Works heaps better. Also large enough to make balancing a bit easier on bigger props.

Size of the magnets i used: 12 x 2.9 mm

( Product number on HK: SK-2050 )

Oh... Sorry for all the fillets. I will try to controll myself next time! =)
