Full Beringer kit : flawless efficiency. The hoses are serious
Airvents from Steinair : aluminium. No air leak, easy to set. Very nice product.
Skybolt camlocs: I just regret to have not converted the hinge around the firewall (already riveted in the QB).
Oil door : 2 Hartwell latches : very safe and flush (vs Van's fasteners).
Tosten military grips : with the modifiued stick for RV 14 !!
Pitot : pitot/AOA by Garmin to G3X. Heated and regulated.
I don't regret any.
