Anyone, ever run out of power with a 65 Cont.? I have!!!!!!! I got agood deal on a 0-290G, and it wieghs the same as the model A 244 lb.or so. Can any one tell me the distance from firewall to prop flangeon the moden A, I can't seem to find my prints. I've got 105.6hrs. on Piet and she realy flies great, Thanks much Robert Bozeman________________________________________________________________________________

Robert,If you are going to go from 65 hp to 125 hp you had better do somecalculations for stress and tail volume. The O-290 only weighs the sameas the Ford "A" but the added horsepower will put additional stress onthe structure. The additional power will cause problems with directionalcontrol unless you increase the verticle fin area.As far as your question about distance to prop flange, that dimension hasno relavence. The point you need to look for is the CG lacation of theengine prop combination and mount the new engine at the same CG location.I hope this helps.David SchoberEli or Robert or Teresa Bozeman wrote:> Anyone, ever run out of power with a 65 Cont.?

Flying with 120 hp engine would make the piet a completely differentairplane. I would like to fly one to find out, but I imagine that TO wouldbe immediate, climb would be spectacular, cruise would be increase by 5mph:) Don't know that the piet would suffer problems with tail volume however.90-100 hp would seem ideal.

220 hp on a Piet! That must have had some climb performance.I've flown "A" powered, Corvair powered and A-65 powered Piets. The Corvair and"A" I flew solo and the A-65 dual. When I flew the A-65 powered Piet dual it wasearly morning, summer, 400-500 foot field elevation. Climb performance was aboutthe same or a little better than a Champ. I weigh about 220 and the person withme was about 130. I can sympothize with you about density altitude and climbperformance. I've been hauling rides out of a 3200 ft elevation strip here in WVthis summer. Thank God for tthe supercharger on the R985 or the Howard would havehad a hard time on those days with density altitudes over 5000'.To get the best performance out of the Piet is to keep the airframe as light aspossible. The structure is overbuilt for a low hp engine but with the O-290 beconservitive.

Pietenpol-List: Re: 0-290G for Pietenpol
Original Posted By: Hatz630(at)aol.com
The corvair was in NX899H "The Last Original". I don't recall the hp but AndrewPietenpol owns the airplane now and should be able to give you the details. The"A" powered Piet was NX83WK owned by BillKnight. The A-65 powered one was owned by Alex Whitmore, I don't recall the N Number.As far as performance, they seemed to be comperable. The "A" nad the Corvair Iflew solo and the A-65 was dual. It was about 12 to 15 years ago so my memorymay not be accurate, but as I recall, the A-65seemed to have the best performance followed by the "A", then the Corvair. Eventhough the Corvair is supposed to have more HP, that big slow turning prop onthe "A" seems to do a better job. I don't knowif Bill had a basically stock "A" or if it was set up for higher HP.Hope this helps. BTW, I just had someone tell me today that they are giving mean "A" engine. I guess it's time to get serious about building a Piet rather thanjust make comments.Mark Boynton wrote:> David:>> You mentioned that you flew a Piet with Corvair power. do you recall which typeof engine it was (as in horsepower rating), and how was the performance?
