Mont in MI
I have a Texas Taildragger 150M with the 0-200, so the performance is nearly the same as the tri-gear.
1)In my airplane with full fuel the useful load is 355#. I weigh 195 so that leaves 160 for the passenger.
2)Fuel burn at altitude,leaned is conservatively 6 gal./hr.
3)Airspeed at 2550-2600 rpm at altitude with just me is about 95 kts.
4) Take off and landing distances seem to be about the book values.
5) Insurance this year was $1156 with Avemco. I have more than 1,000 hrs. of tailwheel time, but I am also 78 years old, so I don't know if this is a useful benchmark.
Since you are going for the 150/150 this may not be too helpful.
