| Subject: | Engine selection for float plane |
Good morning all,
I've decided upon the Light Miniature Aircraft Super Cub replica as a building
project, and I want to ensure that the aircraft is suitable for safe, reliable
float operation. The designer has told me that it would work well on floats,
so there's the first hurdle, and building manual describes that the airframe
has been updated in the plans to accommodate larger/heavier engines than the plans
originally called for some 25 years ago (originally the 65hp Rotax 532).
A number of builder are installing engines from the A-65 through the O-200 on their
aircraft, and the designer also suggests that there has been interest in
the Rotax 912. I'm presuming that all are suitable engines for a floatplane,
however I'm curious if some are better suited than others.
As I recall, Paul S. is using a Rotax 912 on his aircraft and that seems to be
a popular choice on a number of LSAs that are going on floats these days. With
the 912 being a newer engine, however, I suspect that the availability of them
on the used market is lower, and I've noted that the prices are quite a bit
higher than a quality used Continental.
Are there any schools of thought in this regard? Does 100hp from a 912 equal 100hp
from an O-200 equal 100hp from a VW conversion? If the engine develops rated
horsepower with the same length prop, does it really matter which one you
choose?
Thanks and best regards,
Chris
