Jetprop is a fantastic machine for sure. Gross weight is definitely an issue. Most people will tell you that they fly the Jetprop up to about 100 pounds over gross but you had better be careful in doing so if you’re going to encounter turbulence. There’s certainly been quite a few of these aircraft that have penetrated Thunderstorms or other turbulent air and have regretted it. With that said, obviously know the limitations of your Aircraft. You cannot beat the operating cost, and the overall cost per mile in this particular turban.

I looked at lots of SETP options and landed on a JetProp.
For me it was the best choice hands down. It is the most efficient and cost effective per mile turboprop available... There are over 320 of them flying around today - there is a reason it is arguably the most successful STC conversion out there.

With any airplane I strongly suggest you talk to real owners with real experience or folks that fly/train in them everyday.

For reference I burn ~16 gph at idle / taxi

~45 gph in climb (1500 - 2000 fpm into the low 20's. 1000 fpm thereafter) Climb fuel burn does go down as you get higher and become temp limited.

~33 gph in cruise. 257 TAS is my average depending on temp and weight will move the +/- 4 kts
