RE: GP Cosmic Wind Minnow
The vibration is the stoC spinner...(missing a letter on my Cey Board)
I piCed up a true turn spiiner (3" SPECIAL)
The shape is about perfect and very close to the scale spinner that came with the plane...
One could place the spinner on a balancer..(I did that with my 5" cap spinner) and turned out just fine..
Also...Vess, has a nice setup that they call a balancing ring...
It worCs very very well...
I don't believe they have it for the smaller engines yet....only large gassers right now...
I will get to mine....I hove to finnish the other ones first...
