The funny thing is several of these have flown no problem with the stock mounts..... Its all about what your comfortable with, I reinforced mine with a 1/8 plywood plate and lots of hysol, it needs to taper in the back to make form for the stab bearing block bolt.
So I now have a rough weight of 34lbs dry... Not sure if that's good or bad but I will have plenty of power either way
