Proposal 1  ‐ ModificaƟon of NAMBA rules D.1.a and D.1.d for P‐Limited Motor Types in SecƟon 28 ‐ Electric.    Reasoning:   This purposed rule change is to update the current FE P‐Limited motor types from a list of motors to a motor that fits within a specific size   measurement. Many of the motors on the list are no longer available, and going to a measurement method allows more opƟons and can easily   be verified during a technical inspecƟon.    Current Rule:         D. CLASS SPECIFICATIONS             1) POWER SPECIFICATIONS                  a) The following motor and cell configuraƟons will be considered official for electric racing in NAMBA:                 d) P‐Limited Approved Motors                       i) The motors shall be used as shipped from the manufacturer, with the excepƟon of creaƟng a drive shaŌ flat spot, adding water cooling,                          and allowing the motor to be connected to the ESC by any means.                       ii) Currently approved motors                       iii) In addiƟon, the CD has the discreƟon to allow the following:                            (a) An aŌermarket motor that is a re‐labeled and exact copy of any approved motor.                            (b) Any generaƟonal change of an approved motor, or a motor that is used in a Ready To Run (RTR) offering from a manufacturer                                  that produces over 100 units of said offering, as long as there is no more than a 5% increase in any of the following                                  Manufacturers specificaƟons as compared to any single approved motor: Kv, maximum constant amperage raƟng, mass, and MSRP.                            (c) The race flyer shall list addiƟonal allowed motors for the event.   Proposed Rule:   a) The following motor and cell configuraƟons will be considered official for electric racing in NAMBA:                   d) P‐Limited Motor Type Requirements                   i) Motors shall be of an inrunner design and shall not exceed the following dimensions:                       (a) Length: 60 mm (2.362 in.), this includes any bearing protrusion                       (b) Diameter: 37 mm (1.457 in.)   Class   Motor Type   Actual Voltage Limits   Capacity (mAh)   P-Limited   Any single motor  from the approved motor list , see rule D.1.d below.   11.10 ‐ 16.92 V   10,000 max  Brand   Model   DescripƟon   AquaCraŌ   AQUG7000   L36/56 7.2‐18V – 6 pole brushless   AQUG7001   36‐56‐2030 – 6 pole brushless   AQUG7002   36‐56‐1800 – 6 pole brushless   Himax   HB3630   1500 brushless – 6 pole brushless   ProBoat   PRB3310   A3630‐1500 – 6 pole brushless   PRB4017   A3630‐1800 – 6 pole brushless   DYNM3835   A3630‐1500kv – 6 pole brushless, water cooled, marine motor   DYNM3830   A3630‐1800kv – 6 pole brushless, water cooled, marine motor   Class   Motor Type   Actual Voltage Limits  Capacity (mAh)   P-Limited   Any single motor  that meets the P-Limited requirements , see rule D.1.d below.   11.10 ‐ 16.92 V   10,000 max
