4.2.1 Radio Control Class 1/2A

Sailplane Limited Motor Run (LMR)

For event 604.

Any speed 400 motor of any voltage rating with non-replaceable brushes. The motor may not be modified except for timing. The battery pack is limited to 8.4 volts nominal of any battery type. The motor run is limited to 90 seconds but may be made shorter at the discretion of the CD. The motor run time shall begin at launch. The prop must come to a full stop to assure the model is no longer under power.

The flight task is an eight (8) to twelve (12) minute duration (or less at the discretion of the CD) with a precision landing time requirement. At the discretion of the CD, the timing will begin either at launch or when the motor is turned off and will stop when the model first contacts the ground or any ground based object.

Three (3) to Six (6) flights will be performed (exact number will be at the discretion of the Contest Director) with battery charging between flights. Scoring will be based on the sum of all the flights. Each second of flight time will be recorded as one (1) flight point. Each second in excess of the "target time" will result in one (1) penalty point.
