   Hi Doug,
   Yes, side loads on the engine will create side loads on the engine
   'sandwich'.  However, I will not routinely be performing any but the
   most gentlemanly of aerobatics so the side loads will only be
   encountered if I screw up a maneuver; hopefully this won't happen
   often!  If this turns out to be a problem I think the engine will
   develope coolant leaks rather than have a catastophic failure.  I
   settled on this design because a RV-4 firewall is only 24" wide and
   I REALLY needed to get the motor mount tubes away from potentencial
   exhaust pipe routing.
