The Hangar 9

Edge 540 accepts gas engines

ranging from 60 through 80cc. The prototype Edges

were flown using Zenoah

G62s and Zenoah GT80s.

The G62 offers good sport performance and is a

good choice for doing all IMAC basic and sportsman

maneuvers. While the G62-equipped Edge doesn’t

quite provide unlimited vertical performance, most

experienced sport flyers find that the G62 offers

plenty of power for all but the most aggressive

types of aerobatics.

If you’re a 3D fanatic or an Advanced or Unlimited

IMAC class competitor, Zenoah’s GT80 offers power

for more extreme vertical maneuvers.

Note: Before beginning this section, remove

the standard GT-80 prop drive and replace

with the 2" prop drive (ZEN20004).

GT80 Installation

Step 1

Fit the engine to the firewall using four

1/4-20 x 1/2” socket head screws, split washers

and blind nuts provided.

Step 2

The GT80 throttle servo is positioned as shown in

the top of the engine box. Mount the servo using the

hardware supplied with the servo.
