Rick,Yes, I would extend the fuselage 6" forward if I were to build anotherPietenpol, and I would also stay with the 2" wider fuselage.I used an Aeronca 7ac engine mount which extends 8" forward from thefirewall. It is OK for -8 Continentals, but with the C85-12 sans starter andgenerator the magnetos come very close to the firewall. Using a 10" mountinstead of the 8" one would cure this problem and move the mass of theengine ahead an extra 2".Graham (CF-AUN)________________________________________________________________________________

ashort fuse Pi...Subject: Re: Pietenpol-List: How you get a 17 gallon nose tank--even in ashortfuse Pi...Graham, I' am planning on using Orrin's plans using the long 172" fuse design. Are you saying that you would extend the fuse firewall an additional 6" (178" total) then extend the engine mount an additional few inches to accomidate a C85?Or rather are you saying that you would use the long fuse verse the short and extend only the engine mount?Thanks, Greg MenocheDelaware________________________________________________________________________________

Greg,My fuselage is the 1933 "Improved Air Camper" version. It likely is the so-called"short fuselage" with the front end designed for the Ford Model A engine. Ihaven't seen the "long fuselage" plans, so am not familiar with the differencesbetween it and the earlier fuselages, but it would seem that the later onewould accomodate the lighter small aircraft engines without modifications. I dunno.Likely there are people on the list who know this, so let's hear from them.I extended my forward fuselage 6 inches, on the authority of Bernard Pietenpolhimself, because I was going to use a Continental A65 engine. This was his recommendation.And I used the Aeronca mount because I had one.My engine mount extends 8 inches forward from the firewall, effectively placingthe engine mounting bosses on the rear of the crankcase 6" + 8" 14" forwardfrom the 1933 firewall location. Without the extended fuselage, a 14" mountwould be required to match my engine position. Again, I don't know if this isrelevant with the newer "long fuselage" plans.The only reason why I would like to have a 10" mount is to get more clearance betweenthe magnetos and the firewall with the C85-12 engine presently installed.With an A65-8 or a C85-8 engine, the rear case is shallower and there is adequateclearance with the 8" mount. If you are going to use a C85-12, C90-12 or0-200 Continental, by all means use the 10" (or greater, as required for balance)mount. We are talking only about the firewall-forward situation and easeof servicing here.Graham Hansen Camrose, Alberta, Canada________________________________________________________________________________
