Great for small, fast, high performance airplanes, from flat foams to built-up 3Ds Electrifly's Ammo Brushless Motors are designed and produced with high quality, power, precision and efficiency in mind. All 20 size Ammo motors share the same physical size and construction, but differ in kV (rpm per volt) power ratings.
FEATURES: Sensorless design requires a Sensorless Electronic Speed Control Slotless design that offers numerous performance advantages including Patented method for overlapping the winds allows for more copper to be packed inside the can to generate exceptional power No heavy iron teeth with air gaps in between results in no cogging which increases efficiency, responsiveness, and power output compared to cheaper slotted motors Precision bearings make these motors very reliable and virtually maintenance free (ABEC3 shielded) Uses Neodymium "rare earth" magnets which are the strongest permanent magnets available with one of the highest temperature ratings in radio control at 302°F (150°C) Uses magnet wires with one of the highest temperature ratings in radio control at 392°F (200°C) Can be used for direct-drive or geared applications Very low RF and electromagnetic interference, poses less risk to on-board radio control radio system Two sets of mounting holes (one set of holes is spaced 16mm apart, requiring 2.5mm machine screws. A second set of holes is spaced 16.8mm apart, requiring screws which are 3mm in diameter) Stainless steel output shaft Two year warranty
INCLUDES: One Ammo motor Three high performance, gold plated, bullet connectors
REQUIRES: An Electronic Speed Control such as the Electrifly SS25 (GPMM1820) A 2mm prop adapter if using direct drive A gearbox if wanting to run geared (not currently available) Three gold plated, 4mm female bullet connectors - GPMM3115
