One of the big reasons is cost. The power plant is the single most
expensive componant in an aircraft and people are loath to buy 2 of
them at the high price they fetch. Ultralights tend to have landing
speeds in the range that an off airport landing is not as dangerous as
their heavier and faster cousins. People fly them in rural areas and
just live with the engine failures. A twin engine configuration also
brings up the asymetric thrust issue which can cause loss of control
below a specified airspeed.

But your sentiment is felt by many, and the topic has been visited on
many occasions here and never fails to stir up controversy. I've
thought about the problem a bit and posted some ideas on my web site:

As for a cheap way to handle feathering props, I like the self-folding
prop idea I've seen on some european ultralights.

Why are there no multi engine ultralight trainers?
I have about twenty hours behind a 912 and two forced landings already.
It sure would be nice not depending on a single powerplant.
Are two 40 hp engines unable to do the work of a 80hp?

Something is horribly wrong, here.

With tens of thousands of hours flown and the average flight over 12 hours,
I bet you can count Predator engine failures on one hand.

By the way,

When they dredged up Gus's SpamCan a few years back, the switch was found in
the "Off" position.

Draw your own conclusions / conspiracy theories.

I'm a little surprised by that, but I guess it is smart considering the
value of the asset.
