Mike75 Posted June 30, 2021 Share Posted June 30, 2021 (edited) I am considering the purchase of a Varieze sans engine. It used to have a C85. I understand other models use O-200B (pusher). I gather other variants of the O-200 (e.g. A or D) cannot be used, because they are "puller" type engines rather than pusher. Problem is, O-200B is not easy to find. I am wondering why the puller type engines can't be used, just turn the prop around. Simple. Maybe too simple? Maybe someone can educate me on this, thanks.

Mike75 Posted June 30, 2021 Author Share Posted June 30, 2021 Just realized O-200A is mentioned in the POH for Varieze, which I found online as a pdf. So I assume it's okay to purchase one and install it, assuming mounting is similar to C85. Quote Link to comment Share on other sites More sharing options...

Anthony P Posted June 30, 2021 Share Posted June 30, 2021 Logic based around words/phrases such as, "rare and expensive", "don't believe", and "lower", seems problematic. (would not pass a design review at my engineering company) Don't "assume" for aviation or explosives. However, tens of thousands of trouble free flight hour from engine configuration X should be a strong argument. Quote Link to comment Share on other sites More sharing options...
Mike75 Posted June 30, 2021 Author Share Posted June 30, 2021 I think this POH was written by Burt Rutan himself, so I'm guessing he's an authority? A better question might be this: Are there any Varieze owners out there that use O-200A? Quote Link to comment Share on other sites More sharing options...
Kent Ashton Posted June 30, 2021 Share Posted June 30, 2021 A good way to find info on questions like this to Google search with the word "forum" in the search, as in "forum varieze engine options". It will bring up various forum discussions you will not find with just "varieze engine options". The electronic Canard Pushers are online an can be searched with a word search.
