While I also offer complete Motor Mounts for a number of aircraft, a lot of builders choose to build their own mount or are building a unique design. Many of these people purchase a Tray, Part No. MM-1. This gives them a running start at completing a strong, accurate mount for their plane.
The Conversion Manual contains an entire section on motor mounts for the Corvair. This includes drawings and pages of introductory technique to aircraft welding and materials. I even include a section on how to structurally evaluate your motor mount with a physical test. The Tray is the primary part of a Corvair bed-style motor mount, and is common to all three styles of motor mounts I have made. The only common aircraft which has a slightly different Tray is the Dragonfly. (I offer complete Motor Mounts, Part No. MM-4, for this aircraft, but no Trays.)
The Tray is made of 4130 aircraft tubing. I use a combination of mig, tig and gas welding to produce each one. The precision
jig for the Tray weighs about 50 pounds, guaranteeing a very high degree of accuracy because the Tray cannot warp while under
construction. It accepts either the stock oil pan or my own Deep Sump Aluminum Oil Pan, Part No. OP-1. The Tray is clearanced to
allow my Oil Pan to be removed without pulling the engine. The Tray weighs a mere 1 pound, 13.4 ounces, but has been incorporated
into Motor Mounts that were tested to 9 positive Gs without yielding. (It didn't even come close to yielding.) Each tray is welded
in our own shop.
The $179 price includes the four firewall mounting Spools and shipping in the U.S. I accept payment by check or money order in U.S.
