May be relevant to the above post, to show the followingcomments: -originally made by Christian Lucas, in Germany:

-He gives the opinion that Hacker does not really have their own motor designs, they just copy from others. He calls Hacker a "German Copyshop".
He states that Hacker outrunner motors are just a copy of Plettenberg motors. Evidently this is what Uwe Plettenberg himself says.
And it is very clear, for instance, that the Hacker Q60-7M F3A is just a copy of the Plettenberg Xtra 30 motor, with the Q60 having a purple colour on the outside, and a slightly different can with a removable rear end housing.

Christian also states that all Hacker inrunner motors are just a copy of Lehner motors ( -and from the above comments, the Hacker inrunner car motoris acopy of the Novak motor ... )

-I have also heard several other people give similar views about Hacker motors.

Certainly, we know from the evidence in this thread, that Hacker outrunner motorsare exactly the same (internally) as:Torque, Z-Hyperion,
Pelikan Foxy, LiPolice, OK Hobby Infinite, Shulman Aviation Fury, Gens Ace, Apache, Pilotage Nova-Line, Sonic Electric, Turnigy SK3 motors
<span style="font-size: small">And it now seems that we can add to this list: BMI Models "Spitz" motors andPrecision Aerobatics Thrust motors ....

<span style="font-size: medium"> -There is nothing different about Hacker motors at all -apart from the purple colour on the outside ...</span></p>
