Scott,
Some good ideas!
I am just now starting to assemble an Impact.
I like to use Rocket City ball links with stainless steel balls.
In the instructions CA virtually guarantees this will cause flutter if you use "single sided" ball links and their phenolic horns.
By single sided they mean does not have the ball of the link sandwiched between two horns.
I don't want to double up the horns.
On the Impact thread an Impact owner suggested and showed how he lamenated the stock horns with CF.
You are using ply.
In your experience does the carbon fiber eliminate any flexing on your horns?
I may go that route...or I may still laminate the supplied phenolic.
Your thoughts?
Thanks!
