Weight & Balance - being revised with panel update.
Useful load is 490 pounds +/- 5 pounds.
For those that argue a C-152 is much better, the 152 has a 15 pound useful load advantage. This is because the 152 has a 75# higher gross but a 60# higher empty weight. With the 152 fuel burn, you can short fill the 150 by 2.5 gallons, have the same useful load, and still have more endurance.
Of course if you load all 38 gallons, you are comparing a 725 mile range of this airplane with the 300 mile range of the 152.
