Fast Electric P-Limited Rules

Motor and ESC Specifications Motors and electronic speed controls (ESC) shall be based on readily available parts from past and current Ready-to-Run offerings by various manufacturers.  Only motors and ESC's on the approved motor list shall be allowed.  Motors and ESC's may be mixed and matched amongst the approved parts as desired.  Motors and ESC's are intended to be used as they are supplied.  Therefore, no alterations or modifications are allowed, unless specifically stated in these rules.  The motor shall be directly connected to the output shaft, no gear or belt drives will be allowed.
Approved Motors ProBoat - PBR3310 A3630-1500 4 pole brushless motor (BJ26, Formula FastTech, Miss Elam FE).
AquaCraft - AQUG7000 L36/56 7.2-18V 6 pole brushless motor (SV27).  AQUG7001 36-56-2030 6 pole brushless motor (UL-1 Superior).
Electronic Speed Controls Any ESC may be used.
Cooling Motors and ESC's may be cooled as desired.  Water jackets, cooling plates, electric fans, etc., may be added as desired, so long as they don't perform an otherwise illegal function.
Contacts and Wiring Originally supplied contacts may be replaced.  Wire length on the power and phase leads may be altered to facilitate installation.  If lengthening the original wires, additional wire may be added to the factory supplied wires.  If shortening the original wires, the final contact to the motor or ESC must be made using the original wiring.  The intent of this rule is to prevent the removal and replacement of the original wiring in it's entirety, by requiring that the final contact to the motor or ESC be made by the original wiring.
Capacitors Extra capacitors may be used to protect the speed controller from ripple current.
Battery Voltage limits and battery specifications will be in accordance with the P class located in the IMPBA rule book, section J.
Hull Length restrictions shall be in accordance with the P class in the IMPBA rule book.
