TRUTURN FAI 3-1/2' SPINNER

[brianyemail-nsrca at yahoo.com]

FWIW I have an ES Composites 92mm (3.63in) spinner
that weighs 54 grams cut out for a 17x12 prop. This
would be a good electric spinner.

My 3-1/4 FAI TT (81mm) Weighs 84 grams w/ standard
backplate. 

ES has some other sizes. 

You could save a few grams.
