Motor
The firewall is pre-assembled with 3mm thread inserts
installed on a 43mm diameter bolt circle (30.4mm x
30.4mm sq).
Depending on the motor you choose you may need to
make modification to the firewall. Below are 2 examples.
Smaller diameter motors can be mounted directly using
the motor’s “X” mount.
Use removable thread locker
with the supplied 3mm screws when installing the motor.
Larger diameter motors like the AJ3910-24p-660KV will
require some additional work.
Start by temporarily
mounting the “X” mount. Use it as a
template to drill 4
holes in the firewall. (9/64” drill)
Remove the motor mount and enlarge
the holes to 5/16”.
( A little CA glue and a file will help clean up the carbon
fiber strands and hole shape.)
Test fit the “X” mount to the firewall and attach the
motor using flat head screws from the back.
After the test fit be reassemble it with removeable thread
locker.
Solder battery and motor connections to your ESC before
installing it if needed. Use nylon zip ties or a hook & loop
strap to secure the ESC to the bottom of the motor box.
