Adverrrun AVR XS Contra Propeller Drive

Adverrun AVR XS Contra Drive is a F3A drive developed to minimize the effects incurred by the rotating propeller. Forces which affect the flight path of the plane are reduced in order to focus the pilots attention on performing the maneuvers. Adverrun uses a combined Belt/Gear reduction gear to drive two Propellers rotating in opposite directions. It has specially been build for F3A use by active F3A pilots.

Weight reduction, suitability for daily use, reduction of noise and attention to little details have been main design goals.

Our contra drive is offered in combination with Kontronik Pyro. It ships pre-assembled including motor and spinner and comes with screws and rubber mounts. All alloy parts are anodized in Kontronik red. To match your planes spinner diameter size you can choose from a choice of 82mm and 85mm spinner.


Adverrun AVR Single Propeller Drive

The Adverrun AVR Single Drive has been desigend in response to pilots asking for ways to push their conventional (single propeller) setups forward. It features more output power at a reduced weight and is an ideal solution for pilots that prefer a single propeller setup over a contra.

The Adverrun AVR SD v2 delivers 3.5kw at a weight of 430g – 480g and will spin typical propellers used in F3A (21×14, 22×12, 22×14). 

Adverrun AVR Single Drive is the perfect choice for dynamic flight.
