THINGS I'LL DO DIFFERENT NEXT TIME

REMEMBER, THE WRIGHT BROTHERS FLEW A CANARD, WITH AN AUTO CONVERSION.

I do not want to start an argument here. But can someone explain to me why a brand new engine for a 1990's car, is $3500, and a rebuilt 30 year old Lycoming is $8000?  My Volvo has never dropped a valve, blew a cylinder or otherwise given up the ghost, yet certified aircraft often suffer such events and still  insist on using outdated  technology.  I know, I am a lawyer, there  are many issues at hand here which are causing Lycoming and Continental to stick to 65 year old technology, but the bottom line is I could spend $5000 for a mid time, 35 year old engine, which might or might not make it to TBO, and then need a $10,000 rebuild.  I would then have a $15000 35 year old engine.  Early in the game I began looking at alternatives.  Soon  I started looking at a rotary.  Simple, good power to weight ratio, and readily available.
 
 
There are many people looking at rotary powered aircraft these days.  Check out http://rotaryaviation.com.  Tracy Crook is at the forefront of  rotary aircraft development. He develops a reduction drive and electronic ignition for rotarys.  There are also many pictures at his site of other rotary powered aircraft.

I purchased a 1988 Mazda 13B engine.  It came out of an RX-7 in which the owner was planning to install a twin turbo.  Several hours later I removed  about 50 pounds of emissions junk from the engine.  Portions of the stock intake manifold will be used.  Two of the four stock  fuel  injectors will be used.  A "header" type free flowing exhaust manifold will replace the restrictive cast iron stock manifold.   Ignition and injection control will be provided by a Real World Solutons electronic controller, specially designed for aircraft.  A lightweight aluminum radiator and oil cooler will also be added.  Total HP should in the neighborhood of 190.
