I built a small plane powered by electric ducted fans and a few RTGs, which is capable of infinite flight. I was flying it on long flights around Kerbin where I set MechJeb to cruise at 4000 m altitude. I noticed something interesting, which is that the maximum cruise speed decreases as latitude increases. At the equator, it could cruise at 280 m/s but this speed gradually drops to 250 m/s at 60° latitude, which is a difference of more than 10%. As I flew back towards the equator, it gradually increased back up to 280 m/s. Even more interestingly, the blade pitch at which this maximum cruise speed occurs decreases from 49° at the equator to 46° at 60° latitude. The electric motors are always at constant (maximum) RPM and the mass of the aircraft is strictly constant as no fuel is involved at all. This is not an issue of bad controls as the plane is just not physically capable of cruising at 280 m/s at 60° latitude. I think the reason has to do with the temperature, pressure and density of air varying with latitude. Can anyone explain?

Duct fan and blades fitting xbox

Struggling with duct fan and current blades on xbox. Were there not duct fan blades? I swear I saw them. They don't seem to be on xbox. -
The current blades dont fit duct fan on xbox. Weren't there duct fan blades specifically for the duct fans or am I mistaken? If so, how do I make the current blades fit?
