    Thoughts on project planes

    I saw an ad for a fairly obscure Zenair project. I checked with Zenair, and they confirm it was a design they sold plans for back in the day but has not been supported for maaany years. The project is far away, but the pics look pretty good, the completion % looks fairly high, and for the price...

    Have you ever?

    Talking to the folks at Sonex one Airventure a while back, when I said I thought the canopy slope was a little tight for me to fly it comfortably, the guy at the booth told me "lots of people fly it from the middle." Not wanting to get too deep in the mechanics of doing that, like how to work...

    Tandem wing (duo mono) old design

    I recently picked up a copy of the old Mechanix Illustrated with the cover story on the Perdel T-1, a duo mono design for a twin engine light attack aircraft proposal. Other than this short article, I don't see anything else about this aircraft. Does anyone know anything about the Perdel...

    AMPERe One stroke engine

    Anybody see the write up in the August Sport Aviation talking about AMPERe and their two stroke and one stroke engine? Here's a link to their site, it's pretty mind blowing. The engine I looked at on the site had these stats: Power: 37.2 KW (50 HP) Weight 10 KG (22 lbs) Engine Type...

    5 blade propeller template

    A long time ago, I stumbled across a book on propeller carving that had a template for a 5 bladed propeller. I can't find it now, and I'm hoping one of the well read members here can point me to the right title, or author so I can acquire another copy ( I likely loaned the original book out...

    Anyone know this aircraft?

    I'm looking for information about an old racing plane, the PAR-1. It was a mid wing pusher from the early 50s. There is supposed to be a write up and 3 view in a two volume set of books titled: Goodyear and Formula One Racers, by Robert Hirsch. I tracked down the books on Amazon, by I'm hoping...

    Longeron orientation and strength

    A lot of common designs in wood use rectilinear bulkheads with longerons at the corners, like a VP1. Would it make any strength difference if the bulkhead were oriented as a diamond instead of a square, with the longerons on edge as well? I attached a crude drawing to give a better idea what I'm...

    Material substitution help

    I'm stumped. I don't have the expertise to figure out an acceptable substitution for a rudder tube. The plans call for 2" X .059 wall, 2024 T3 aluminum tube. I'm not having luck finding that size in that wall thickness, so I wondered if 6061 T6 with a larger wall thickness would work instead...

    Part swaps

    I'm curious if fiberglass or carbon fiber tubes can be substituted for aluminum tubes, for spars or rudder posts, or other structural parts. It seems like the tensile strength can be comparable, but I don't know about other considerations like bending loads, etc.

    VP1 rudder question

    I checked Wicks and Aircraft spruce and Airpartsinc, and I can't find the rudder tube for a VP1. The plans (p.51) calls for 2" diameter x .058 x 55" 2024-T3 aluminum tube. Nobody seems to have it in their online catalogs...Are people substituting, or am I missing a source?

    Need a helping hand on the West coast

    Back before the pandemic, I was the high bidder in an auction for an Airdrome aeroplanes Fokker D8. The problem is, since the pandemic, travel restrictions, hot zones and rolling lockdowns have kept me from going out to get the project and bring it home to Missouri. The seller has been...

    Volksplane wing question.

    I've been seeing VP-1 projects on the internet for good prices, so I bought a set of plans to see what I'd be getting into trying to complete one. One question I've got is, can the wing struts be fastened to a single attachment point, rather than running parallel to two attachment points. Do you...
