As a special feature, the so-called "APOLLO motor" is integrated in the spinner. The motor-spinner unit can thus be screwed directly to a blunt fuselage nose. With this type of installation, the motor moves forward as far as possible for the best possible focus control.
The price is reflective of the contents included in the power kit; this kit includes a motor-mounted spinner with a set of props, as well as an A-15 speed controller.
