Larry,

It's been awhile but if my memory serves me it's right at 7 in.
The Tru-Turn spinner is real light but the double jam nut is
fairly heavy so it's probably about the same as yours.
Let me know how you like it. Maybe we can get together after
the holidays and do some flying. I plan on taking some time off
work after the first...I'm getting too damn old for this working
all the time !!
