gear combination 17 teeth/16 teeth, thus constantly changing tooth mesh / increased service life
6 % higher tail rotor shaft speed
better running smoothness and considerably reduced noise level, especially interesting for electric flight
larger tooth flank engagement
dimensions analogous to Ord.No. 95/5 & 95/6
for all Vario Alu tail rotor gearboxes (ø 6 mm shaft)
Note: The spiral toothing has a smaller module than the straight bevel gears. Therefore it is not suitable for large tail rotors with low speeds (helicopter models with rotor disc > 2m).
