The KV is 820 and they recommend a 13 x 6.5 on 3s

The Thrust 40 is 850KV only 140 grams and is good to 500 watts and 35 amps constant and 45 amps 10 sec burst and they recommend a 14 x 7on 3s. The Thrust motor does not specify what 4s prop to use, only that you should stay within the suggested amps.

Is the Torque motor under rated? Could you safely put a 13 x 5 or 13 x 6 on it with 4s? I would think the lower KV of the Torque would allow for higher prop sizing?
I been using the Torque with 4 cells APC 13 x6 never an issue but now I like the 12 x 6 APC prop less power....
