What, no skeg?;-)
You might consider a less rigid, flexible bonding system, something like the PFM from the hobby-lobby catalog or the silicone-like flexible glue Bob Violett sells, I think it's a cousin to room-temperature vulcanizing stuff... I think what's happening is your fuselage is flexing, oilcanning, under actual launch and landing loads, and the epoxy you use is so rigid, that it's shearing the bonds. If you can't somehow add better shock-mounting to the thing, then maybe an adhesive with some flex to it will stand up better. You might even need more structural bracing in the general area of the gear to deaden that flexing. Or you might go to mechanical fasteners, but that's going to cause stress risers at the bolt holes.
