Note!
If the aero-tow option is chosen, use a servo with at least 10 Kg or 130 in/oz of torque!
To ease locating the proper placement of the complete unit, a 2mm hole is bored vertically
thru the fuselage top, about 70mm to the rear of the canopy opening for the tow-line release
pin. Connect the pin with the servo arm and feed the pin thru the hole. The complete unit is
then positioned in the fuselage, the final spot being set by the vertical positioning of the tow
release pin. Unfortunately, the various case heights of the many servos on the market
prevent us from providing an exact measurement.
3.2. Motor-Montage
The SIAI-Marchetti is an ideal airframe for the use of a "Boxer" type motor, with the 100ccm
Moki 4-stroke, DA-100/120 or other similar motors (3W-110iB2) as examples. For mounting
the generally shorter, two stroke motors, CARF includes a precut plywood plate for extending
the motor dome. For the longer Moki 4-stroke, this part is not necessary.
3.2.1. Motor Installation
The Moki 4-stroke may not be the most powerfull powerplant in the line-up, but the simplicity
of installation – and the SOUND – make it an ideal choice. In contrast to a 2-stroke motor,
the mufflers can be attached directly to the motor dome, eliminating special internal
cutouts/fittings.
Take the measurements for the mounting holes from the photo.
It is a good idea to combine the drilling of the motor bulkhead and the nose gear mount in
one operation.
