Technical data
Adverrun AVR XS has been designed for 10s Lipo packs. We have tested the most common propeller combinations ranging from 20″ to 23″ diameter. Generally we found that higher pitch propellers performs a bit better and recommend using Front: 22×20 / Rear: 22×22. Depending on the chosen propeller maximum currents of 90-120A are expected on the ground which provides more power than needed for typical F3A flight.
Thanks to its powerful Egodrift 570kv 4025EC motor, Adverrun AVR XS v4 is the strongest drive that we ever build. The total weight is 575g.

Specific Features
The Motor shaft is bearing supported in the front carbon fibre plate. An additional rear motor support for the motor is not required. Alloy screws are used to save weight where possible

The Helical Delrin gear and belt drive reqire little maintenance and limit noise

Front and Rear mounting uses rubber mounts to minimize noise transmission into the fuselage. The rear mount allows for smaller side thrust adjustments. The front rubber mounts are spaced so that a ring mount can be used to mount the drive in the fuselage

The rear mount system has been specially designed and can stay in the plane when the drive is removed for service.
