Club Wingman Propulsion System Regulations - Will be adopting these NMPRA EF1 Rules as of 1/1/2012

4. Power System
   EF1 is intended to be enjoyed by the maximum number of potential participants. Therefore, all power system components, including motor, ESC, BEC, battery and connectors shall be off-the-shelf and readily available to the general public in reasonable quantities and at reasonable prices.
   1. Motor
      1. The motor shall be a direct-drive, 3-phase, brushless electric motor with magnets fastened to a rotating outer housing and a fixed armature, with wound copper wire, at the center, commonly known as an "outrunner" style motor. The motor shall be commercially available and in stock configuration as provided by the manufacturer and not modified in any way other than the addition or substitution of items identified in (d) below.
      2. All motors shall be approved for use by the EF1 Committee prior to their being entered in competition. All motors eligible for approval shall be substantially similar in power and performance to the E-Flite Power 25 1250kV - 60A outrunner motor. Manufacturers wishing to have a motor approved for competition shall submit a minimum of three (3) production examples accompanied by a full set of technical specifications and drawings and a detailed distribution plan to the EF1 Approval Committee.
      3. Currently Approved Motors:
         1. E-Flite Power 25 1250kV - 60A outrunner motor
         2. Turnigy AerodriveXp 25 SK Series 35-42 1250Kv
         3. Arrowind 2820/07, 1300 Kv motor
         4. O.S. .25 2-Stroke Brushless Motor 1200kV
      4. The following items are not considered part of the motor and may be substituted as desired:
         1. Connectors for electronic speed control
         2. Drive washer or collets
         3. Mounting hardware
         4. Propeller nut
         5. Propeller washer
         6. Spinner
   2. Electronic Speed Controller (ESC)
      1. A commercially available brushless Electronic Speed Controller with a minimum of 60 watt rating shall be utilized and controlled by a separate throttle channel.
      2. Speed controller may incorporate a Battery Eliminator Circuit (BEC) which would eliminate the need for a separate battery to power the receiver and servos.
   3. Battery: Battery shall be a commercially available Lithium Polymer (LiPo) battery.
      1. Maximum Number of Battery Cells: Motor battery shall have a maximum of 4 cells, and all cells shall be contained in shrink tubing.
      2. Maximum Battery Weight: Motor battery pack shall have a maximum weight of 325 grams including all connectors, wires and shrink tubing. It is recommended that batteries utilize a balancing tap to balance the individual cells as part of the charging process; however, batteries without a balancing connector are permitted and shall have a maximum weight of 315 grams.
      3. Battery Retention: There shall be a means of positive retention of the battery pack within the airplane to prevent it from shifting during flight.
   4. Wires and Connectors: Wires and connectors shall be of a sufficient capacity to accommodate the power system rating. All wires or connectors shall be fully insulated and protected. No open or unshielded wiring or connecters are permitted. Connectors shall be polarized and of sufficient size rating. Wiring for transmission of current to the motor shall be a minimum 14AWG rating. ESC wire to the receiver’s throttle channel shall be a minimum 22AWG rating.
   5. Propeller: Deviation from EF1 Rules due to airframe differences. Any size of propeller may be used and it may be modified.
