Because of the expense of a firect drive we will have to possibly giveup our ddream of building a Piet. Now if someone can tell us if it canbe flown with a direct drive soob then we just cant fit its expense intoout budget.Steve & Emelita W________________________________________________________________________________

Don't give up because of engine cost. I wouldn't consider a direct driveSubaru. RPM's are to high and not enough bearing area to absorb gyroscopiceffects of the prop.Go to antique car flea markets and find a Model A. You should be able tofind one for less than $500. Learn to scrounge all you can. If you work atit you will be able to build a Piet for suprisingly little money.Steve W wrote:> Because of the expense of a firect drive we will have to possibly give> up our ddream of building a Piet.

The road to get there is partof the fun! I agree with one of the other comments that direct drive auto conversions with modern engine aren't a good idea. The cranks won't take the prop gyroscopic load. The Model A or B has a very long rear main bearing that used to carry the heavy flywheel. The B engines bearing size is almost the same dimensions as a Continental's. Besides that the large prop disk works better. Henry Ford made hundreds of thousands of these engines and with patience and determination I'm sure you can find one. " Argue for your limitations and sure enough they are yours!"If you stick with it some day you will suceed. If you can't find a Ford engineclose to home contact me and I'll help you find one.John McNarry________________________________________________________________________________
