6. Mount the landing gear to the fuse with threadlocker,
four 8-32 x 3/4" [19mm] SHCS, four #8 flat washers and four
#8 lock washers.
❏
7. Repeat steps 1 through 6 for the other landing gear leg.
❏
1. If you are using a DA100, cut the engine mounting
template from the rear of this manual. Align the printed lines
with the lines on the firewall and tape the sketch in place. If
you are using a different engine, use the template provided
by the engine’s manufacturer to center the engine on the
embossed lines on the firewall.
❏
2. Drill 5/16" [8 mm] holes through the firewall at the
locations indicated by the template.
❏
3. Mount the engine to the firewall with 1/4-20 x 2-1/2"
[64mm] bolts and the correct number of aluminum spacers
required to make the total distance from firewall to the thrust
washer at least 7-1/2" [190mm].
❏
4. After reading the caution provided immediately following
this step, and remembering the importance of maintaining at
least 12" [300mm] between anything engine/ignition related
and anything radio related, follow the engine manufacturer’s
instructions to mount the ignition module. On our airplanes,
we mounted it inside the top of the firewall box.
Because of the possibility of ignition engines creating
radio noise, we use a plastic pushrod for the throttle
servo installation.This isolates the engine and any radio
noise from the servos. This is an IMPORTANT selection,
and we cannot recommend strongly enough that you
DO NOT change this pushrod to a metal pushrod. All
radio equipment – including throttle servo, receiver
battery, electronic kill switch, receiver on/off switch,
servo leads – should be mounted at least 12" [300mm]
away from anything related to the ignition/gasoline
engine. Any material used between the engine and the
radio equipment is STRONGLY recommended to be
plastic, nylon, or otherwise non-metallic and non-
conductive to minimize ignition noise transmission.
