Just a heads up for folks who get a QB fuselage. Part of the overall building process is to insure we check the QB parts over carefully to match to the plans. This is a critical gusset as it supports an engine mount attach point.
I found some of the 8 bolts installed on the f684 gussets were torqued others were not. They look finished but because the nuts are under the part if is not possible to see torque paint. Only way to be sure is to check the torque.
