Gentlemen,I recently purchased a prop from Beres & Hirsch (sp). I think it is a 72 x44 although it is not in front of me. My question has more to do with theconstruction of the prop. It is made of only threelaminations--Maple--Black Walnut--Maple. It is supposed to be a "Scimitar"type prop which I think means that it flexes (pitch changes) when power isadded.Most of the props that I see have several more laminations. Have I createdmore grief for myself?I have attached their web site and email address if anyone is curious. Theyseem like knowledgeable guys and say that their props are flying on otherPiets. Their prices are quite reasonable.http://infoseek.go.com/?win=_search&sv= ... empnet.com Distribution Design Specialist * Lucent Technologies, Inc.________________________________________________________________________________

Dear Russell, Not to cause you concern but the only prop I have seen that used threepieces of wood (two laminations) delaminated at one, inch long location.However, the owner had stored it inside his home for the winter. Too muchheat and lack of humidity may have really been the problem. You can e-mailLonnie Prince and he may be able to help you. Lonnieowns Prince Aircraft Inc. and they advertise their props each month inSport Aviation. His work has appeared on numerous EAA Grand Champions.Lonnie is the most knowledgeabe wood prop man I have ever talked with. Goodluck.

Russell, I haven't seen any comment on your point that you felt that a scimitar prop refers to one that flexes or changes pitch. I have always understood that a scimitar prop (or scimitar anything...usually a sword) describes the shape of the prop rather than any other characteristicDon Hicks ________________________________________________________________________________

Don Hicks and Randall Reihing,Thanks for the info. on the propeller I thought that perhaps the fewerlaminations (3 layers = 2 laminations) made for a less rigid structure whichallowed for some flexing. I think that I read in a propeller article inExperimenter that some of the early propellers (such as seen on a SopwithCamel etc.) were designed to flex and effectively change pitch (to a smalldegree). I thought they used the term "scimitar" when refering to theseprops. Mine looks like these older props. The blades are more round outnear the end. Kind of spoon-shaped. I am not familiar with a scimitar sword. Is it also somewhatspoon-shaped towards the point? Thanks again,________________________________________________________________________________

Hi folks,Piet list newbie here. I and a buddy are putting one together we hope to have flyingnext summer. We recently scored a low time A-75, clean as a whistle inside.Regarding props: so far in what I have gleaned from comments here and there, agood choice for this combo would be in the 72-38 to 72-40 range. One poster commentedthat a 72-42 seemed a bit too much load and kept the engine from reachingtop revs during takeoff. I guess it makes a good cruise prop though.Maybe this topic has been covered in ages past, but I didn't find too much in myfeeble search attempts.Any comments?Thanks!Mike D.--------Piet-builder-who-hopes-to-be-flying-next-summerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Welcome to the list Mike. Props are always a good subject. I'm flying behind an A 65 and have a Struba 74 X 38. Works very well for me both in climb and in cruise. Someone else on the list had a Struba 76 X 38 with an A 65 they were happy with.The main reason I went with Struba is because he will repitch the prop as many times as it takes to get it right for free. I'm sure you will get a lot more input from the others.Gene> ________________________________________________________________________________
