Tim,

I've got pretty little carbon spinners that fit right on a 7" crush plate
and are just pointy enough to cover the mechanism.

I've also got a Franklin/Ivo Velocity I'm painting that's going to fly
out  Jan. 8th that might could use one of your/Ivo's new big crush
plates.
I wouldn't call your 7" plate "experimental".  That's the only size Dan
and I ever used from the beginning.

Happy New Year

Alan
