Note: The firewall has been set up to accept the Fuji-Imvac
BT-43EI gas engine and as such the instructions have been
written to reflect this. 8-32 Blind nuts have been preinstalled
for your convenience for mounting the Fuji-Imvac engine. If
you choose to use another manufacturer’s gas engine within
our specified range, it is up to you as a modeler to
determine the best mounting method.
