Wingtip Tanks, Winglets And Tail Boom Fairings For C336 Or C337.

[Alfonso]

I would very much appreciate if anyone who is using or has used the winglets and or boom fairings, and the 20-gal. wingtip tanks with STCs for the C336 made by Aviation Enterprises of Nashville, TN, to please provide me with any information as to its effectiveness, efficiency, lower fuel consumption, speed improvement, and all the good and or the bad of them, if any.

Also if anyone has had an FAA Field Approval for any wingtip tanks, please let me know, as I want to do the same to my C336.

Lastly, does any one has ferry tanks available for sale or can recommend a place to build them?

Thank you for your help. Alfonso. Cell 202-309-3969.
