Can't climb over 8500 feet

[Midnight Music]

I must be doing something wrong. My Beaver will climb slowly to 8500 feet, but then will stall if I try to go higher. I use 50% fuel and a light load. Any advice will be appreciated to get a bit higher in altitude.

This is in P3D V4.5

Okay, I may have figured it out. I need to keep flaps on climb rather than retract them...my bad!
