PREPARE THE ENGINE
1. Check to see that all screws and bolts are tight. Check carefully for any cracks, broken or missing parts.
Tighten or replace before proceeding.
2. Install the engine mounting stand-offs on the engine using four 5mm x 22mm socket head cap screws.
3. Secure the ignition control module ground wire to the engine using one of the 5mm x 25mm socket head
cap screws.
4. Connect the ignition control module to the pick up sensor. The connector is polarized and will only plug in
one way.
5. Connect a kill switch to the ignition control module. It is recommended to install a manual switch and a
servo operated switch. This can be accomplished using two receiver On/Off switches.
6. Connect the ignition module battery pack, it can be used any 5 cell or 2S Li-Poly packs with at least
700mAh. Do not allow the battery to drop below 4 volts or damage to the module could occur.
INSTALLING THE SPE-26cc ENGINE ON YOUR AIRPLANE
Note: The length of the engine from the back on the engine mount to the propeller washer is 154mm [6.0625"].
1. Use the supplied laser cut plywood mounting template to drill the engine mounting bolt holes and the
necessary clearance hole on the firewall.
2. Install the engine on the firewall using four 5mm x 25mm socket head cap screws, four #10 flat or lock
washers and four #10 blind nuts. Use thread-locking compound for security
3. Install a manual and radio operated kill switch (EDR-107). Purchase from Cermark. Install a kill switch
servo at least 305mm [12"] away from the engine.
4. Install the throttle servo at least 305mm [12"] away from the engine. Make sure that you get the carburetor’s
full range of rotation with your servo travel.
5. Install the ignition module securely in the airplane forward area. It is recommended that a thin piece of
foam rubber be placed between the module and the mounting surface and that rubber bands are used to
hold the module in place. 4mm [5/32"] screws and washers can also be used to secure it in place, but soft
mounting the module is always the best choice.
6. Secure all connections with shrink tubing.
Note: The SPE-26cc engine must be installed on a 9mm [3/8"] lite-ply firewall or on a 6.4mm [1/4"] birch
ply firewall. The firewall must be securely glued to the airplane. Use triangle stock and pin the firewall with
hardwood dowels to reinforce the firewall glue joints. Never install the SPE-26cc engine onto a firewall
thinner than specified because it may fail due to the power of the engine.
7. Cut all necessary clearance and cooling holes in the cowl.
8. Make sure the cowl is secured to the airplane and that the spinner to cowl clearance is at least 3mm [1/8"].
BREAKING IN THE ENGINE
Do not adjust the high-speed needle on the carburetor to break in the engine. If you do so, carbon will accumu-
late in the spark plug and that will make ignition difficult. · Do not run at full power for extended periods of time
while breaking in your engine. · Make sure that the engine has adequate cooling. While breaking in, the engine
may run at slightly higher temperatures. · If you wish to do so, you can break in your SPE-26cc while flying your
airplane. Just make sure you observe all recommendations above.
