Hey everyone, I'm new to the forums, but I've tried it myself and got to a pretty low altitude (8km) on a low-power, cobbled-together plane. However, I have some useful data. These were the average climb rates from takeoff to the altitudes listed: 0-2km 16.67 m/s 0-3km 18.34 m/s 0-4km 18.54 m/s 0-5km 18.34 m/s 0-6km 14.33 m/s 0-7km 14.64 m/s 0-8km 11.32 m/s Keep in mind that this isn't very consistent, but it gives a general idea of where the atmosphere thins a lot. I built up speed around 2km, 5.5km, and 7.5km, so keep that in mind while looking at the results. The atmosphere seems to get a lot thinner above 5km, and then another drop of performance is encountered at about 7.5km. I couldn't climb faster than about 1.5 m/s above 7.5km. (This plane had 18 m/s initial climb rate) I reached 8,101 m before stalling. Thanks!
