Bellow is Basic calculations of thrust for the RS1106 Motor and Prop Combo.

The single 18650 or Dual 18650 will be boosted up to the Desired voltage using 2-3 XL6008E1 running in parrell to achieve desired voltage.

\\————-————————————————————

Power of a Single 14500 is ~2.6W (~ 3.7V * 0.7Ah)

Power of a Dual 14500 is ~5.1W (~ 3.7V * 0.7Ah)

Power of a Single 18650 is ~9.25W (~ 3.7V * 2.5Ah)

Power of a Dual 18650 is ~18.5W (~ 3.7V * 5.0Ah)

\\————-————————————————————

The weigh of motor, 4x Servos, ESC, LED and 1x 14500 is 86g 

(20W Flight + 10W led => 5.2 min flight time

The weigh of motor, 4x Servos, ESC, LED and 2x 14500 is 100g

(24W Flight + 10W led => 9min flight time

The weigh of motor, 4x Servos, ESC, LED and 1x 18650 is 114g

(28W Flight + 10W led => 14min flight time

The weigh of motor, 4x Servos, ESC, LED and 2x 18650 is 159g

(48W Flight + 10W led => 19min flight time

Using the Below Thrust tables Optimal flight time Configuration

1) Single cell 18650 Boosted to 8V 

2) RS1106 (4500KV)

3) GF3020 Blade

4) 3.5A Current at 8V

Assuming no efficiency losses Flight time could be ~ 19min

Realistically flight time could be as high as 13min
