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

Adverrun 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.

Technical data

Adverrun has been desgined for 10s Lipo packs. We have tested the most common propeller combinations.

These combinations will yield in maximum currents of 90-120A on the ground providing more power than needed in a typical F3A flight. Good to know that there is the little extra power for storms though ;-)

Weight has always been a concern in F3A and one of the reasons for the three year development phase till we were satisfied. Weight depends on the used motor type. It is common to state weight of model drives without accessories. We list weight w/o accessories for comparision with other drives, but also including spinner and accessories (i.e. screws and rubber mounts). Compared to other drives Adverrun also limits the need for using additional CFK mounting plates to fit the drive in your plane.

Helical Delrin gear and belt drive reqire little maintenance and reduces generated noise.

Front mount and rear prop mount. Adverrun is mounted with supplied rubber mounts.

Rear mount allow for small side thrust adjustments. Rear mounting uses rubber mounts to minimize noise transmission into the fuselage. We use 0° side thrust

Motor shaft supported by front bearing. No extra support needed for the motor.
