These mounts can be glued or taped to your plane. The image on the left
shows the firewall mount plate installed for firewall mounting motors.
The image on the right shows a blue wonder installed, clamped on the 8mm
bearing tube. All mounts come with the slot modified standard unless
otherwise requested. This modification allows for easy installation and
removal of the motor in the event of a ground strike. The square part of
the mount is just under 10mm (.392in.) so it works great on 9mm EPP
foam, and 1/4 in foam as well. The 8mm hole goes all the way through
both ends so if you wish you could cut the mount in half and use the
tube mount for one plane and the firewall mount on another, thus getting
2 mounts for the price of one!
