The long fuselage prints were made by Vi Kapler to accommadate thecorvair engine. I do not have the precise figure, but I think it is 19 feetsomething. The extra length was added in the cockpit aera.2. That is one method. Another is to move the wing back.( as I did. )I knowof a Piet that has added lead weights to the motor mount.3. The CG of the Piet has been discussed for as long as I can remember. Itis my impression that most Piets are flying near 20 inches. Not to becontentious, but I believe that is a tail heavy condition. In my opinion theideal is between 14.5 & 18 inches. ( rough test, lift the tail to straight &level, let go. the aircraft should teeter. That's good ) 4. rough figure. add 100 lbs. 65=165. 85 = 185 plus. 0-200 minus altenator& starter about 200 lbs, with accessories about 225 lbs.( I fly with a0-200) The ford engine weighs about 240 lbs with the Al head minus the water5. the data can be found in the repair manuals.6. Can't help there.I don't mean to go on here but, if I were to do it again & wanted a C65Piet, I would build a Greiga. It was designed for the engine.Mike B ( Piet N 687MB )________________________________________________________________________________

It is designed for the Cont. a-65 thru o-200and is very similar to the piet.________________________________________________________________________________
