I epoxyed and glassed mine before I even started it up, and had no issues I would strongly advise anyone who gets one of these to do the same. I strenthen all mygas motor mounts as soon as I get them as Ihave found the gas vibswork loose the crap hot glue on the arfs pretty quickly. I especiallydone it on this model as I agree it is a weak design and could be dangerous ifthe motor let loose.
I also have now bought the new yak version, not that I did not like my sbach but the yak seems to be better at least on paper for wing loading, hope it flys as well. I have glassed and added tri stock to the yak motor mount also before first start. Hopefully maiden today and do a flight report on the other thread I started here.
