This DX2807A 2807 1300KV brushless motor is presented as a premium option for a 7 inch FPV racing or long-range drone. The maker says it delivers impressive thrust and efficiency, across a 3S to 6S LiPo range.
The specification list gives a KV of 1300, a maximum power of 921 W, a maximum current of 41.5 A, an efficiency of 2.42 g/W, adapted propellers of 6 to 8 inches and a rated input of 22.2 V (6S).
Motor seat hole spacing is 19 x 19 mm. The title says 4S to 6S while the description says 3S to 6S, so treat 4S to 6S as the safe range and 6S as the tested voltage. Choose an ESC comfortably above 41.5 A, or use a 4-in-1 ESC rated to handle that peak on each motor.
For long range, a large, low-pitch propeller gives the best efficiency. Balance your propellers, use thread lock on the mounting screws and check the bell for play after crashes.
Pilots building a 7 inch long-range or cruising quad who want a lower-priced 2807 with a known power rating.
A 7 inch propeller with a moderate pitch usually gives the best flight time on 6S with this class of motor, while a more aggressive propeller trades efficiency for speed. Log your current on a first flight, compare the average against your battery capacity to estimate flight time and adjust the propeller until you are happy with the balance.
