2. Gearbox and starter combination

No gearbox, recoil starter
Use only if you are planning to install a third party belt reduction drive.
included
Rotax 2-stroke aircraft engines produce their power at high RPMs. Propellers need to turn much slower.

The B type gearbox is the most economical and lightest model available. It is limited to a propeller mass moment of inertia of 3000Kg/cm2 (about propeller mass moment of inertia)

Although the C and E type gearboxes are available and compatible with the 447UL, they are not usually necessary in most applications. Contact us if you are considering a 447UL with one of these gearboxes.
B type gearbox, recoil starter
Available with reduction ratios of 2.00:1, 2.24:1, 2.58:1, 3.00:1
$932.00
B type gearbox, electric starter
Electric starter installed on the magneto end (opposite the gearbox). Includes starter solenoid.

Either install this air filter directly onto the carburetor...

Can be rotated to suit most installations.
$193.00
Or install the intake silencer with air filter. A major part of the noise of a Rotax 2 stroke aircraft engine is the clatter emanating from the carburetor's throat. The intake silencer efficiently muffles this noise. Slight effect on power: about 2% loss.
