<span style="font-size: small">Worth noting: Torque 4016T/500 (280g) is EXACT SAME motor as: Hacker A40-10 L V2, Kv 500, 10T =Turnigy SK3 4250-500kv, 10T =PA Thrust 50, 487Kv</span>see: http://www.rcuniverse.com/forum/fb.asp?m=11428699</p>

-Above RCG thread says: Motrolflys are extremely popular
many run the Motrolfly 4315-480Kv with 16" props.
The Motrolfly runs very cool compared to others
These Hacker and Torque motors are often used with 14", 15" props -however they have a higher Kv.
The Hacker A40-14 L , Kv 355, 14T -has a lower Kv, and will swing a larger prop ...</p>

AS FAR AS MOTOR TORQUE IS CONCERNED:
Hacker publicity / marketing / hot air<span style="font-size: small">ALWAYS</span> states:
<span style="font-size: small">"... The Hacker ... A- *** ... ... This 14 pole, Outrunner design creates MASSIVE TORQUE, therefore larger direct drive props can be used without the need for a gearbox ..."
</span>e.g. https://www.aero-model.com/8_67_887/...-10L%20V2.html</p>

-Perhaps Hacker motors really <u><span style="font-size: small">WOULD</span></u> create <span style="font-size: small">"MASSIVE TORQUE"</span>-if they had a design like Motrolfly, with a larger diam and shorter length stator ...</p>
