While doing some research on the old reed type radio
control systems, I ran across this superb video that has the producer interviewing
Mr. John Donovan, AMA #8557. John has been flying R/C since the 1950s, worked for
Phil Kraft at one time, and now owns Donovan's
Hobby & Scuba Center, in Sioux Falls, SD. OK, I get the hobby part, but
scuba gear? Anyway, he produced a great tutorial on how a lot of the old system
components worked. As with most things in life, it was the pioneers like John who
took the arrows - otherwise known as the learning curve - so that the rest of us
can enjoy the wonders of today's radio control systems.
