I'm sad to say that IF your engine fell off, NO TRIM in the world could
compensate for the missing weight.
What you can do is secure the engine to the airframe with metal cables, like
formula one airplane racing guys do. That is what was required when metalic
props were used. The blades were liable to fatigue failure, and a the
out-of-balance condition resulting from a missing blade tip at 3000 RPM
could very well tear the engine and mount off the fuselage.
I know one guy whose engine tore off on initial climb. Fortunately it stayed
attached to the airframe by the control cables and lines, and he succeeded
in directing his half-controlled fall into the lake below. He swam off the
wreckage uninjured.

Best wishes,
Gilles Thesee
