Hi Eugen,

I never used the green urethane foam. The fuselage shells were built using ¼” foam (rear shells) and 3/8” foam for the forward shells. They were made using vacuum bagging in female molds. The fiberglass used for those shells was lighter than the 9oz bidirectional fiberglass that is used for wings/bulkheads/fuel tanks.  I am not sure of the weight of that cloth, since the shells were pre-built at the factory. There was one Tri-Q built in Canada without the use of the pre-made shells, so it is possible.

All of materials you list below are available from Aircraft Spruce.

Cheers,

Jay
