The rear cantilever section of the fus does not have any internal support its only supported by the glassfibre skin of the fus, a Fuji would rip it straight off the back, would be an interesting first flight, but rather short I think.

Do you think the weight is the issue or the thrust? The weight is just over a pound more and the thrust (based on the prop I will be using) is the same as a JetJoe I had on a previous Falcon.
Neither I think the issue will be the vibration and the loading on a not so perfect landing, I drilled a 11mm hole through from the back into the inside area of the fus and Hysoled in a 10mm carbon rod along the root internal rib, the problem with the bottom brackets in the Falcon is they have nothing to attach too.

EDIT: Canterlever should be 1/3 out 2/3's in i.e. if the overhang is 50mm the inside support should go internally by 100mm.
