The mount is in, trimmed and holds the weight well. It also has been cured, so there should be no issue with the heat from the engine softening the resin. I am having some custom fasteners made to secure the mount to the aramid chassis – similar to these  but to my own dimensions and specification of metal. I can then hard mount the engine mount to the chassis. I’ll also need to make a torque-control bar that attaches to the engine and stops it yawing when it spins up.
