Section 18 – Electric Motor Installation

Required Parts

• Fuselage

Required Tools and Adhesives

• Electric motor (Hacker recommended)
• Electronic speed control (Hacker master 70-3P)
• Electrical connectors
• Heat shrink
• Appropriate motor mount (Aero-Model)
• Propeller (APC 16x12E)
• Plywood (for battery mounting plate)

There are numerous possibilities available for converting
your FuntanaS™ 90 to electric power. The following
instructions cover the installation of a Hacker power
system using Lithium Polymer batteries. A little creativity
and ingenuity will be necessary to make the conversion,
no matter what motor/battery combination you select.

Step 1

Carefully measure and mark the centerline on the
firewall using the measurements as shown.

Step 2

Check the location of your particular motor. It may be
necessary to remove material from the firewall to allow
for motor clearance.

Step 3

Install the motor mount of your choice. The Aero-Model
mount is a perfect fit and uses the original engine
mounting locations.

Step 4

Attach your motor to the mount. Position the mount so
the motor is 5
