Engine Installation
Your kit comes with both a firewall pre-mounted and an extra firewall for DA-200 installation. You can choose
from a wide variety of engine choices. It is nearly impossible to cover every engine installation choice in this
manual but we’ll cover a few. Your aircraft was designed around the 150cc to 170cc twin gas motors as well as
the 200cc quads. Also, we have provided a canister/pipe tunnel on our Edge for those desire quieter operation.
Please consult the manufacturer for the installation of optional canisters/pipes.
The best way to get perfect alignment with the motor and cowl is to stand the fuse on it’s tail and rest the motor
in place on the firewall. Rest cowl in place, adjust motor, and remove cowl mark and drill. While you can use
the pre-marked firewall, this may by slightly off due to variances when cutting the cowl from the molds.
DA-150/170 installation
The firewall is pre-marked so you'll just need to center your motor in the "+". Take a ruler and draw a
line across the entire firewall for the thrust line and offset centerline.
DA-150/170 users only.
Center the motor based on your dimensions and drill out the holes for the ¼-20
bolts.
Mount the motor using 3/4" standoffs for the DA-150/170, and four 1/4-20 x 2" long bolts.
Now that you have the motor mounted, mark the locations for the fuel line and throttle push rod remove
motor and drill those locations and reinstall motor.
We recommend 4/40 push rods for throttle and/or optional choke servo. Also ensure there is no metal-to-
metal contact from the throttle/choke to the servos. 2/56 Ball links for 4/40 rod (not included) will prevent
the aforementioned metal-to-metal contact and will bolt to nicely to your motors carburetor.
