I am building a V-6 STOL (starts with a tri-pacer, wings and fuselage

It looks as though the gross weights are similiar to a BD-4. How feasible
would it be to mount the BD-4 center spar in the tri-pacer to allow BD-4
folding wings? Obviously the control would have to be modifed a la BD-4.

Not very feasible!

1. The Pie Chaser has a strut-braced wing and is therefore too weak to
support the cantilever structure of the BD-4 wing.

2. The BD-4 has a tubular spar, which, again in incompatible with the
Tripe's structure.
