Quadspex did a series of motor thrust tests that shows the power of 716  motors vs  615 motors into perspective. I’ve computed the thrust-to-weight ratios and summarized the results in the convenient table below:
| Motor | Thrust (g) | Total Thrust (g) | Thrust-to-Weight Ratio* |
| Stock 615 E010 | 7.83 | 31.3 | 1.252 |
| RS 615 16000KV | 9.3 | 37.2 | 1.488 |
| RS 615 18000KV | 11.2 | 44.8 | 1.792 |
| MMW 615 17000KV | 11.37 | 45.47 | 1.818 |
| MMW 615 19000KV | 13.03 | 52.13 | 2.085 |
| Stock 716 E011 | 17.27 | 69.1 | 2.303 |
| MMW 716 17000KV | 18.47 | 73.9 | 2.463 |
*Assumes 25g take-off weight for 615 quad; 30g take-off weight for 716 quad
