The way my trim is set up (based on Mike Cuy's design) the springs are attached directly to the bellcrank for the elevators. If the cable from the rear stick to the bellcrank breaks, there is still the possibility of flying the airplane with the trim. If a cable breaks between the bellcrank and the elevators, both cables would have to break before you would totally lose control. If one broke but the other was intact, in theory you should be able to control the plane with only one operable elevator. Of course, if the bolt that holds both elevator cables to the bellcrank comes loose, you in a heap o' trouble. Jack --> Pietenpol-List message posted by: ZigoDan@aol.com The only draw back about Mike Cuys trim system is that if for some strange reason a cable breaks, or there is loss of stick control to the elevator there is no back up. That is why on Cessna 150, Champs, Cubs, the trim is a total different system. You can land a 150, champ, or Cub in an emergency with trim only. I have thought about building one elevator with a cockpit controllable tab.

Haven't figured out exactly how to operate it but will likely use a Bowden cable. Shimming the HS would make a lot of sense to establish level flight in average WB without needing trim. Almost any trim method will increase drag. Drag is the Square of the speed so every little bit hurts.

I have a short fuse with an A-65. I still havent installed the brakes, so I came out with an empty weight of 550 lbs and a c/g of 12.2 with the cabanes raked aft 3.5 in. Does this sound in line with others? These figures include installing a 6 gal nose aux. tank empty and a 12 gal. wing tank. With this weight I might consider installing a 35 amp battery in the nose (35 lb.) for a transponder and radio. Dick
