plug in wings and stabs?
 

how do they stay on? what type of system is used to hold the wings/sabs to the fuse in the rod and tube connection?

What holds 'em on?
 

For an example, the BVM BobCat has a plug- in outboard wing panel. The two aluminum tubing spars plug into a slip-fit phenolic tube socket, and each wing is retained by a single 4-40 allen cap screw.
The flight loads are carried by the tubing spars and sockets, and the 4-40 screw merely prevents the outer panel from sliding spanwise and saying "goodbye" to the wing center box. The screw may seem small, but it is in "shear", not "tension", and consequently is not subjected to flight (bending) loads.
The stabilizers can be done in a similar method on a conventional length fuselage.
The BobCat uses four (two per side) 6-32 x 2" bolts to hold the stab between the booms.

Hope this answers your question.
