A Piet with vortex generators! ;o) I think one of the ways to make it STOL-ish is to try the approach used by John Dilatush with his turbo'd, redriven Subaru. I think his plane pops off the ground pretty handily just due to the added muscle. My thought is that one could certainly apply a more efficient low-speed airfoil to the airplane, but this gets into the category of 'sacrilege' among Pieters.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Subject: Pietenpol-List: Ford engine mt.Hello Gene. Yah, I'm going to build my V's to extend to the foreward endof the ash bearers. If I had already made them standard length, I woulduse them as made, but since I haven't built them yet i'm going to attachthem per the plans. They will just be a bit longer. I am going to usethe same 1" drop at the front for the same down thrust as the plans. TheV's are the only steel parts that I still need to build. I am not goingto put in any offset. If I have any trouble there I will put a bendabletrim tab on the rudder. I have made attachment points for tabs on myrudder and elevators just in case I need them. 2 years ago I bit thebullet and just bought the engine mt. V's from Replicraft. They arebuilt from the 1929 plans in the Flying and Glider manual. Those planshave an error on the down thrust. ( at least I think it's an error ) Theplans say 2 1/2" down trust. I think that should be 2 1/2 degree, notinches. I put my Smart Tool level on the barers and found that 1" dropcomes out to 2 1/2 degrees. 2 1/2 in. looks like a radical drop. So Ihave a pair of Replicraft engine mt. V's that I can't use. I bought thembecause I am building in my living room, and can't do any welding there.In the Flying and Glider Manual there is a picture of a Piet with thecowling off. The tubing part of the mt. is not joined together in Vfashion. The lower tube is bolted under the ash bearers, and the uppertube is bolted to the side of the bearers. BHP got away from that on thelater plans. This is a simpler way to build the tubing part of theengine mt. ( less flitting, less welding, etc. ) Does any one know ifthis is an inferior way to build the tube part of the engine mt? Buy theway, in an old Buckeye news letter, Frank Pavliga suggested building theModel A fus. fire wall 4 in. foreward rather than extending the enginemt. Either way, I think it shows that that old Ford A "boat anchor"rneeds to be moved foreward at least 4 in. Good luck, I'm off to dreamland. Leon S.
