As for the original thread -

Along with being reasonable to purchase and operate, implying a "take
home" plane, it should not be so fragile that ground handling becomes
a problem.

Another factor that I think is going to become even more
important ............. it should have a power plant that can operate
on standard auto fuel - alcohol and all. If snowmobiles and 4
wheelers can operate at 14,000+ ft density altitudes on auto fuel
there must be a way to make LSA's do the same?

The more frustrating problem might be to make it run on av-gas, although
echanics have also told me that may be a non-issue as well. Basically, if
you are willing to accept the as delivered reliability of the automotive
FADEC systems, which have become very good, then the primary issue would be
lead fouling of the oxigen sensor--the the mechanics have told me that the
oxigen sensors do not fail in the conventional sense, due to lead fouling;
but only become slow in their operation. Since aircraft engines are
normally operated at continuous output levels, and the FADEC systems are
capable of operating with enriched mixture in open-loop mode when at maximum
power and also while the oxigen sensor catches up, the lead fouling problem
may be trivial in most cases.

Just a thought, for what it's worth and withh the understanding that I am
not really taking a position. In fact, there appears to be mounting
evidence that the total cost of a conversion might not be much of a saving
over the purpose built aircraft engines.
