Presentation : Scratch build semiscale Delta II SSBN Projekt 667BD

[JHapprich]

Hello! This is my scratchbuild Delta II SSBN. Length 1,2 m. Hull has been constructed from an inner 76mm sewer pipe with tubes cut lengthwise glued upon it to increase the wall thickness of the hull. Dry-hull design with locking screw in the forward bulkhead. The sail and bow+ stern are epoxy-grp, the rudders/planes and the missile-section are made from sheet-ABS. Pictures show layout from 2015. Last year i began a refit, including production of copies of the heavy planes and missile compartment from lighter urethane/ grp and replacement of the balast roller pump, switching to lipo battery and
replacing the two ESC's
