(suggested minimum requirements)
5A Servos to be rated heavy duty with a minimum of
24 inch ounce of thrust for non-critical control
functions, and a minimum of 45 inch ounce of thrust
for stress functions The use of one servo for each
aileron and one for each stabilizer half is strongly
recommended Use of dual servos is also
recommended
5B On-board batteries shall be 1000MAH up to 20
lbs , 1200 MAH to 30 lbs , 1800 MAH to 40 lbs , and
2000 MAH over 40 lbs flying weight.
5C Redundant and fail-safe battery systems are
