GWS Tiger Moth Motor Mount Broke!
All is not lost. Don't toss the entire plane for want of a motor mount. Broken motor mounts are common, and as was mentioned before, if they were made out of something tougher, something else would break.
If the break is fairly ragged and fits together well, you may be able to simply glue the stick back together. A little dab of medium CA or wood glue, then press the stick pieces back together, and it's as good as new! Just don't let CA get on the foam. CA melts foam.
