If you want a setup which will support and allow rotation - make a second rotating ring at nose of model and suspend the engine between the two - I did this years ago working on YS emgines
The forward ring was attached to fuselage via four angled, tubular pieces of carbon fibre
the whole contraption worked very well but a pain to build
I made my own Rotomount for years -did same thing as the expensive mounts -
