Mike,

It might be labor intensive, but I will bet that you can make the elevators yourself. You probably can still get the hardware from BVM.

You might be able to laminate contest grade balsa over a central core of 1/32" ply. Sand the balsa to the proper airfoil shape and glass the assembly. The pivot tube must be securely attached as well. The carbon fiber plate that BV sells to strengthen the stab assemblies (this is included in the F-16 turbine conversion kit) might be useful here.
