POWERED BY LINUX!!
Tom Parkes Turbo 3 Rotor Powered Lancair ES

DON'T CONFUSE THIS ENGINE WITH AUTOMOTIVE PISTON ENGINES CONVERTED TO AIRCRAFT USE or SO-CALLED ALTERNATIVE ENGINES. The rotary has a much better power to weight ratio and power to size ratio than any automotive piston engine. It is also far more robust and will withstand ungodly amounts of turbo boost with out major structural failure. Any piston engine operating at aircraft power levels has a limited life. That is the reason for a TBO. The moving parts are magnafluxed for cracks at TBO. The cracks are caused by reversing stress on the crankshaft, connecting rods, pistons and valve parts. Bend metal back and fourth long enough and it will fail. The rotary has no reversing stress in the 3 moving parts. They are eccentric shaft and two rotors. It is similar to an electric motor and there are many 100 year old electric motors still working. Automotive piston engines are not designed for aircraft power levels and should not be used. The average power required for a car is 30 to 40 HP!

COMBINATION PSRU ADAPTER PLATE AND MOTOR MOUNT. Saves the weight and cost of a Schertz beam (10 pounds) and is lighter (6 pounds) than Tracy Crook's adapter plate (7.5 pounds). The loads on the spacers are reduced greatly as they no longer transmit prop torque loads to the motor mounts located on an oil pan spacer plate (another 8 pounds) if used. Think about it. Prop torque is 2.85 times higher than engine torque due to the gear box reduction. Engine torque on a Mazda rarely exceeds 200 foot pounds even with a p-port or turbo. Prop torque on the other hand is 567 foot pounds due to the gearing. This torque is reacted directly by this motor plate. There fore loads on the spacer and bolts is greatly reduced with less chance of misalignment.

P-PORT PARTS FOR SALE. Contact Paul Lamar at the email address below.


Bell mouth $5 each. plus shipping.


Oil injector hole pressure tap. $20 each. plus shipping.


RX8 style injector blocks. $15 each. plus shipping.



RX8 water pump outlet block. Clears slide throttle. Tubing bends and fittings not included. $150 each. Will not clear apex seal oil metering pump as most people don't use them in aircraft. They mix 2 cycle oil with the fuel.





Slide throttle kit. Tubes TIG welded to covers. Weight 2.2 pounds. .032" thick Teflon sheet not included. $120. each cash. Plus $15 for shipping.



Here is the type of Teflon to purchase for lining the slide throttle. Very important. Not all Teflon is created equal. Some has a higher coefficient of friction leading to higher forces on the throttle. Particularly with the 3 rotor version. In that case use a 2:1 lever to increase the throttle travel and reduce the force by half.
