I guess by logic the P-100 should fall somewhere between the P-80 @ 22 lbs and the P-120 @ 28.5 lbs.

Kenrico, since you just started flying turbines I doubt you remember, but the P-80 was a 17lb thrust turbine at one time. Jetcat made improvements and the P80 went to 18lbs, then 19lbs, and up to 22lbs where it is at now. The great thing is that the P-80 has remained just as reliable as it has always been even though the power has increased by five pounds over the years.

I would imagine the P-60 will be around for a long time because of the segment of the market it fits. I have owned several P-60's over the years and they little jewels. One of my favorite turbines.
