Recommended Power System and Main Blade Configurations
When using the recommended main motor, pinion, heat sink, battery and main blade configurations below, we have
experienced very good main motor life (better than any other models in this class). We have main motors in stock
and Aerobatic Enhancement Kit equipped models with more than 100 flights that continue to perform very well.
For those who may experience premature main motor wear, it is likely the result of excessive current draw causing
damage to the motor rather than brush wear. Excessive current draw can be the result of using the wrong main
motor, pinion, heat sink, battery and main blade configurations, improper gear mesh or constant power on blade
strikes and crashes (shock damage). For these reasons you MUST follow the power system configurations
recommended to achieve expected motor life. These configurations are:
EFLH1110A - 370 Main Motor with 8-Tooth Pinion:
For use with 3-cell Li-Po packs and flat bottom main blades. This is the most efficient setup for long duration
hovering and basic sport flying when using 3-cell Li-Po packs. Must use a heat sink (EFLH1132).
EFLH1110B - 370 Main Motor with 9-Tooth Pinion (Included with the Aerobatic Enhancement Kit [EFLH1168]):
For use with 3-cell Li-Po packs and flat bottom main blades for hovering and sport flying, with less duration than
when using the main motor with 8-tooth pinion. Also for use with 3-cell Li-Po packs and symmetrical main blades
for sport flying and aerobatics. Must use a heat sink (EFLH1132, also included with Aerobatic Enhancement Kit).
We suggest 860–900mAh packs for all-out aerobatics with durations up to 15 minutes and 1200–1320mAh packs
for basic aerobatics and longer durations up to 25 minutes or more.
EFLH1110C - 370 Main Motor with 10-Tooth Pinion (Included with the stock Blade™ CP heli right out of the box):
For use with 8-cell Ni-MH packs and flat bottom main blades for hovering and sport flying. This is the most efficient
setup for long duration hovering and basic sport flying when using 8-cell Ni-MH packs.
NOTE: DO NOT USE THIS MOTOR AND 10-TOOTH PINION WITH 3-CELL LI-PO PACKS AS IT WILL DRAW EXCESSIVE
CURRENT RESULTING IN SHORT MOTOR LIFE, EXCESSIVE RF NOISE POTENTIALLY CAUSING RADIO “GLITCHES”
AND DAMAGE TO THE 4-IN-1 ON BRIEF BLADE STRIKES OR EVEN DURING FLIGHT.
Use of a heat sink is optional (EFLH1132), though it can help to improve duration and motor life.
EFLH1110D - 370 Main Motor with 11-Tooth Pinion:
For use with 2-cell Li-Po packs and flat bottom main blades for hovering and sport flying. We suggest packs from
860–1320mAh.
NOTE: DO NOT USE THIS MOTOR AND 11-TOOTH PINION WITH 3-CELL LI-PO PACKS AS IT WILL DRAW EXCESSIVE
CURRENT RESULTING IN SHORT MOTOR LIFE, EXCESSIVE RF NOISE POTENTIALLY CAUSING RADIO “GLITCHES”
AND DAMAGE TO THE 4-IN-1 ON BRIEF BLADE STRIKES OR EVEN DURING FLIGHT.
Use of a heat sink is optional (EFLH1132), though it can help to improve duration and motor life.
Also, we find it is best to allow the main motor to cool to near ambient temperature between flights.
