Mounting the Engine
The Vision 3D has been specifically designed for the DA50R gas motor,
designed and manufactured by Desert Aircraft.
Many other suitable motors are available that can be used to power the Vision
3D, but the next steps in the instructions describe the mounting and fitting out
process for the DA50R.
First, using the template provided below (a template of the correct size is at
the end of these instructions), mark mounting holes for the 4 DA50R
standoffs.
The template positions the motor with the cylinder head at about the 7 O’clock
position. This will allow a pitts style muffler or header for a pipe to be fitted,
with minimal cutting required in the side of the cowling to clear these items.
Now drill the standoff mounting holes and remove the section of firewall that is
required to clear the carburetor.
It is important that 1-inch squares of 2-6 oz per sq inch fiberglass cloth are
applied to the firewall over each standoff mounting position. This will stop the
standoff from compressing and more importantly wearing the wood, which will
cause the motor to loosen. Clue the squares of cloth in place using medium
CA.
