Butch,
That looks...................awesome!
I like the DIY midpole snuffer- very nice.
Did I see the spin clew blocks mounted on the rear beam?
Have you tried a higher aspect chute that clets to the shroud area?
You obviously got the rudders to be parallel, they look good on there. Let us know how they handle. Probably pretty good.
Having made my own snuffer tubes, yours looks great.
