"39" Fuel Helps Set New World's Model Plane Endurance Flight Record
of 8 Hours, 31 Minutes, 50 Seconds...
The mechanical-minded young and not-so-young who fly model airplanes
in tethered circles have a new mark to fly at. Last week Sherman Holt,
14, of Fayetteville, N.C. kept a model plane in the air for 8 hrs.31
min. and 50 sec., leaving his nearest competitor more than seven hours
Farm Boy Holt built his first (5c) model at the age of six. Since
then he has been working toward bigger projects. A few weeks ago he
had the idea of refueling his latest model through a plastic tube running
up the control wire. With the help from older fans, he fitted the model
with an extra gas tank and rigged the plastic tube.
First trial which was at night, lasted for 3 hrs. 43 min., but was
cut off after a counter-offensive by kept-awake neighbors. A good part
of Fayetteville was on hand during Sherman's next flight. Every seven
minutes or so, he pumped fresh gasoline into the tank. The flight would
have lasted even longer if the extra gas tank had not vibrated loose.
If the model had been flying in a straight line, it would have covered
257 air miles.
