Why are there no small turboprops?

"David CL Francis"

Did you know you can buy true turbo jets for model aircraft? They cost
about $3000 and give about 20 lb thrust, They are around 4" in diameter.

And wear out in a few hundred hours, at best, and consume vast quantities of
fuel.

I just did the figures on the one above. If I didn't make any
mistakes, that tiny engine burns almost as much as a 300 HP IO550.

The pair of them on the Cri-Cri would be burning in the neighborhood
of 30 GPH at full power.

If they wear out that fast, how well does that Cri-Cri fly on one engine? Seems to me
that would be a real problem fairly regularly.

It's not economical to use a small turbo contrasted to the payload.
