Model Engine Home Made 1936 Midget Magazine plans.wmv
Home built four stroke engine. Built using drawings from 1936 issue of Popular Mechanics magazine. Wood patterns were made, then used to make sand molds. Old car pistons and transmission cases were broken up and melted in a small propane furnace. The molten aluminum was poured into the sand molds.
Next each part was machined on a 1941 South Bend lathe. Using an old model airplane engine spark plug and coil, two D batteries were hooked up to create 3 volts for ignition. Contact points are from a 1977 GM V-8 engine. The fuel tank is an old glue can.

First Flight of a Bentley BR2 Rotary Engine
A bit of modeling history was made on December 4th when Robert Cooper's twice-size model of Lou Proctor's "Antic" took to the air powered by a Blackmore-designed Bentley BR2 rotary aero engine. Dubbed the "GIGANTIC," Robert's aircraft lifted off at Hodges Hobby Shop (Andersonville, GA) at about noon with Mac Hodges at the controls. The engine and plane performed flawlessly, and although it was in the air for only a few minutes, we believe it may have set at least two world records. As far as we know it is the first model Bentley BR2 to take flight and the first ¼-scale model rotary engine to power a model airplane into the air.
Robert Cooper designed and built the aircraft, and Paul Knapp built the Bentley BR2. Ray Williams developed the fuel control system and assisted in all aspects of the engine installation. Ray Williams was the first person to successfully fly a model rotary engine when he flew his 1/3 scale model 160 HP Gnome in December 2001. His Gnome engine is on exhibit at the Craftsmanship Museum in Vista, CA. A stainless steel version of Paul Knapps Bentley BR2 is also on display along with many other engines and outstanding examples of miniature craftsmanship of all kinds. Visit the museum on-line at www.craftsmanshipmuseum.com. A tour of the Craftsmanship Museum can be seen on YouTube by doing a search for Craftsmanship Museum.
Congratulations to Robert Cooper for his beautiful 12-foot wingspan "Gigantic" and a successful flight. Special thanks go to Ray Williams for his expertise and assistance, Mac Hodges for his experience at the controls, Dale Cavin (Contest Director) for clearing the air for the Gigantic, and Glenn Torrance and Robert Warner who helped prepare the aircraft for its maiden flight. Video documentation by Paul Knapp.
NOTE: The first part of the video shows the initial runup of the engine. The actual takeoff starts at about the 6:30 point of the video. Except for one high speed pass, most of the flight was flown at 1/2 throttle. The 12.5 pound engine has plenty of power.
Engine Running NO OIL - NO SUMP - Seized Soild on Camera
Messing with a Mitsubishi Lancer
There are loads of videos where people run an engine at full rev with no oil in it, and the engine seizes.
Running it a medium rev, I wanted to see how long it would run with no lubrication, and I was surprised.
However if the car was driving and the engine was under load, it would be dead in minutes!
