55% Scale Sikorsky S38. First of a kind.
1st twin engine (Rotec R3600x2) Project.
The project was well under way before Rotec heard from Gordon Jones and Ken Coe that they had talked Walter into taking on the construction of a 55% Scaled version of the Sikorsky S38 amphibian.
We at Rotec were delighted to hear that their intention was to power this plane with two Rotec's nine cylinder, 150HP engines.
Steady progress surmounting the many problems en counted during the construction phase the most difficult being constructing a special mount suitable for an amphibian with the engines mounted on the wing.
