"MIND THE LINES" - How many times have we heard the irate model owner shouting at people who "should know better"?
After many years I have reached the conclusion the ONLY reason my lines get stepped on is because I left them out, line park or no line park. Reel 'em in and reel 'em out for every flight if you want to guarantee your lines don't get stepped on.
That's a good idea when practicing but can create extra work at a contest.
The AMA general control line rules state the following:
3. Size and Type of Control Handle. Control handle,
fixture, or device, shall not extend more than six
inches (6) beyond the hand of the operator except in
cases where control is accomplished by means of
twisting a line, in which case the maximum extension
shall be no more than 30 inches. Unless prohibited by
the rules of the particular event, control handles providing
for easy adjustment of line length are permitted
provided they are equipped with a positive safety
lock.
Lines may be stored between flights, but
lengths must be measured before each official flight.Altering line length after official measurement is
cause for disqualification.
