I have two things I'd like to discuss. As I wrote previously, I have thecutout in my wing and feel that it is absolutely necessary for access tothe cockpit and for visability. I have my radiator tucked under the FordEscort; just think what the turbulence must be off the Model-A radiatorfacing the wind squarely in front of the center section of the wing. Justhow efficient can that center section be in the Model A versions? Cuttingsome 3 or 3 =BD square feet out of the wing equals a lose of just thatamount, particularly on the trailing edge. Last evening as I was flying Ialso found out that my crash helmet sticks some 1 or 2 inches up into thecut out area. For someone my height, 6'2", the cabane struts would haveto be lengthened to gain clearance. I can't image lowering the seat anybecause my legs are reasonably tight now. Of course, if I didn't use acushion at all, I'd be 1/2 " lower. When turning base on approach, I lovebeing able to look under the wing and over it at the same time. I feelthe safety factor, alone is worth the lose of a few square feet of wing. I do have a problem I could use some suggestions on. The Ford Escort withstraight pipes is pretty loud--probably an understatement! With tightearphones in my crash helmet, it doesn't bother me at all. I need asimple, compact way to cut the noise down some without losing itsdistinctive sound. I have all four exhaust pipes going into a single tubewhich is around 2 =BD or 3 inches in diameter--can't remember exactly. Idon't want to add anything with much leverage because of the vibration andcracking. I've heard that a motorcycle spark arrestor might cut the noisea little. I don't want to got to a full exhaust system with a bulkymuffler hanging in the airstream such as some of the 2-stroke people have. Suggestions???________________________________________________________________________________

William,A friend of mine has suggested installing an internal type spark/nois=earrestor as was used in VW's. Take a thin sheet of stainless about th=elength of your straight section. Take a 3/16 inch dia. nail and punch= holesinto the entire sheet. role the sheet so the sharp side if the holesareagainst the exhaust flow. Set the roled sheet on stand-offs inside yo=ueexhaust, and keep it in place with a few stainless machine screws. Th=isshould work. I'll be doing just this for my corvair.regards,Dom.

Ian, I have a 1986 1.9L Ford Escort in my plane. It is converted usingthe conversion kit once marketed by Ed. Libtz, a Canadian Airline Pilot. I probably didn't spell his name correctly. As far as I know the kitisn't available any longer. Basically, the engine is turned around, thedistributor is moved and operated by a 1 to 1 cogbelt from the overheadcam pully on the serpentine belt end of the engine. A cast iron 2.5 to 1reduction psru is created on the other end. Basically a small cog pullyis bolted to the center of the flywheel and a larger one to the front ofthe engine using just two bolts and a spindle with tapered bearings. Theprop is bolted directly to the larger cog pully. My unit has about 66hours flying time with no major problems. The carb is modified slightlybut other wise the engine is stock with both starter and alternator. Total weight is around 300 lbs with around 80 hp. My plane solo takes offin 2-300 feet and climbs like crazy; this is from a strip located at 4860feet altitude. >>> Ian Holland 11/25 11:24 AM >>>Hi! I have been following the discussion with interest, particularlyregarding the use of the Ford Escort engine. Is there anything that youcan share with how to convert/use as an aircraft engine? Year, type,power, type of reduction etc? Corvairs are getting darn hard to find!________________________________________________________________________________
