Burgerup, where did you place the aluminum back plate that comes with the engine to fix it in the firewall?
Arruba,
Due to the construction of the Top-Flite kit you are unable to mount the backing plate without cutting it in half, so I reinforced the back of the fire wall with two pieces of 1/8'' ply epoxied to the back of the fire wall. I have since installed the vibration isolator and mounted the backing plate to that. I also used larger hardware.
