10. If you are using the DA120 this step will be quite simple, figure 18 will help identify the
various parts. The firewall has marks that show the location of the holes to mount the
standoff. We highly recommend and use the Blazing Star engine mount for the DA120.
You will need to drill holes at the marks, we recommend starting with a nail punch or awl
to make a small indentation, then use a small bit and working up to a ¼” drill bit, see
figure 17. This method will help keep the hole centered. Trial fit the standoff and engine,
we used ¼” X 2.5” bolts (not provided) and both delrin spacers that are included with the
Blazing Star mounts to achieve the desired spacing. Once the fit is as desired, you may
secure the engine to the plane, but sure to use BTL on all bolts.
Other engine installations will likely be similar. However you may need to adjust the laser
marked holes in order to get the engine to center with the cowling. Also consider your
distance from the firewall to the front of the cowling for your standoffs. This distance is
185mm or 7 9/32”.
You may mount your throttle servo at this time. See figures 19 and 20 to help with this
process. A pushrod, ball link and EZ connector are included to help in this process. Also
included is a laser cut package that will aid in an alternate throttle servo mount.
Whichever engine you choose figures 20 and 21 will illustrate what a final assembly
might resemble. You will notice I bent my throttle pushrod to my preference, use your
past experience to decide what works best for your motor. Note I used a piece of velcro
and a simple servo mounting screw to secure the fuel line, this will keep the line from
interfering with the throttle servo or touching the hot engine.
