Installing the DLE-170 on Your Airplane
Note: The DLE-170 must be installed on at least a 3/8" [9.5mm]
fi rewall. The fi rewall must be securely glued to the airplane. Use
triangle stock and pin the fi rewall with hardwood dowels to
reinforce the fi rewall glue joints. Never install the DLE-170 onto
a fi rewall thinner than specifi ed because it may fail due to the
power of the engine.
Note: The distance from the fi rewall to the propeller washer is
8.34" [212mm].
1. Use the supplied template (on the back cover of this manual) to
drill the engine mounting bolt holes.
2. Install (4) 6mm blind nuts or tee
nuts (not included) into the back
side (non-engine side) of the fi rewall.
Install the engine to the fi rewall
using (4) 6x45mm SHCS with 6mm
lock washers and fl at washers (not
included) with the included standoffs. Use some threadlocking
compound, such as Great Planes
® Pro ™ Threadlocker (GPMR6060)
on the screws where the threads enter the blind nuts.
3. Install the fuel tank in the airframe. Use only gasoline-safe fuel
lines and a gasoline safe stopper.
