LITTLE ANGEL, by Bob Shores
Originally, I built a 1/2
scale Witte headless engine from a casting kit that turned out to be a nice
engine, easy starting and reliable. I scaled it down to about half size and
built one from bar stock that also turned out nice. Scaling down again, I built
the Little Angel and exhibited it at Zolfo Springs. Many request for the
drawings resulted in a “Drawing package” to offset expense. The first “drawing
package” was sold to Brian McCartin in January 1994. A very large number of
these little engines have been built, worldwide. One was built on an aircraft
carrier in the Persian Gulf and Alex Neilson built 7 Little Angels, one for each
grandchild. A very popular engine. During the past 8 years, the original engine
has required no maintenance and has acquired more than 600 hours of running
time.
