The amps 1/4 scale cat hull has been around for 30 years to my knowledge.
same with the large scale 2 stroke outboard.
Ive had a few of the amps products, the amps tigershark, the amps miss enfield etc
this stuff was originaly made in the uk.
ive also still got an outdrive i bought from amps back in 1980 from the T.M products factory,
in chatteris, England.
T.M Products was where the amps stuff was manufactured in the uk, in those days amps was considered pretty good stuff.
From memory i think the 1/4 scale tunnel was based on a full size seabold.
Lots of rc boats using the large scale 2 stroke outboard used to race in londons docklands.
They never were a match for the high powered glow engines, but they did look nice and
gave a more scale look at their slower speeds.
