Thank you for your always kind replay DrMotor.

About Motrolfly motors the interesting thing , getting them in paragon to all standard B. motors,
is exactly the fact that they got larger diameter and the shorter in length rotors.
This,
You can sure teach to me ,
improve torque and one bit penalize consumption.
More torque , mean that Motrolfly motors can flip larger props.
I think ( IMO ),
the future of the brushless motors for RC planes , will be in this direction.

Interesting is the fact they are not made on the 'usual' China factories, like all B. .

About my in build MXS EF unfortunately I bought one Hacker already 2 moths ago,
before read this tread!
