The flight route is about 1, 900 miles (3, 057 kilometers) 36 hours of flight, but much depends on head winds and tailwinds. The plane generally cruises at 42 miles per hour, but tailwinds could boost its speed to 60 mph or more. It can fly in head winds of up to 30 mph, but would burn fuel too fast to make it to the Irish coast.

After guiding the craft—named for Beecher Butts, an 88 year-old aviation enthusiast—to its cruising altitude, Maynard Hill will put the plane on autopilot and, from his safe seat in Newfoundland, anxiously await its arrival in Ireland. Pilot Paul Howey and others will be in Ireland waiting for the plane to appear on the horizon. They will head out to the bog and, if the plane comes in, take over manual control and land it. FAI officials there will be able to certify the record achievement as well.

What is the plane made of? Balsa wood and mylar film (Monocote©) are the principal materials, with cyanoacrylate glue used to harden and connect much of the structure. Carbon fiber, fiberglass, and epoxy are used in areas requiring extra strength. Careful attention to design allows the components to be very light with adequate strength.

What powers the airplane? The airplanes are powered by O. S. FS-61 four-stroke engines. The engines have been modified and are equipped with electronic ignition and a spark plug to enable them to run on gasoline. What is the fuel? The fuel is Coleman stove/lantern fuel, with a special additive for lubrication. This fuel has a high energy content, is very volatile.

How is the airplane guided? The autopilot uses a microcomputer to process data from the GPS, receiver, pressure sensor and gyro to adjust the signals to three control servos. Steering, altitude hold, and engine speed are separate servo loops. Prior to launch, a memory chip is programmed with waypoints for steering. The chip also is programmed with desired altitude and engine RPM between waypoints. The complete algorithms are proprietary.

What electronics are on board? A Futaba receiver, Futaba servos, and a piezoelectric rate gyro are combined with a commercial Global Positioning System (GPS) receiver. The autopilot is a custom design by Joe Foster who wrote all the software. A pressure sensor provides altitude information. This altitude system is calibrated periodically by data from the GPS. There are two miniature telemetry transmitters.
