RE: Skygate/CARF Viperjet
I think you will find Nandon's method of fixings is absolutely fine.
The connections on the fus side are hard mounted as in the pic and it looks to me like the connections from the wing are not going to be hard mounted to the wing but left loose to plug into the fus outputs, so there will be no stresses on the connections at all. Neat and tidy solution and leaves one hand free to do other things with !
