You don't need a PayPal account, you can proceed without one and use any VISA/MC card. They are just the payment processor. Of course they take advantage of the opportunity to try and get a sign up. Happy Launching! Arrr! Capt'n Skunky KSP Community Manager
Try using the WSADQE keys to rotate them. You can also hold SHIFT while rotating for finer control. Happy Launching! Arrr! Capt'n Skunky KSP Community Manager
The reason this works is due to the quick and dirty implementation of aerodynamics. Wings and control surfaces can propel a craft forward by alternating their position which induces momentum. I'm sure someone can explain this better than I, but that's the gist of it. This will be fixed when we implement a proper aerodynamics/atmospheric model. Cheers! Capt'n Skunky KSP Community Manager
This is what I need to show my contact at NASA that's involved in educational outreach. Let me know when you have a some data on how well it works and when you've perfected your lesson plan. Maybe we can get NASA to pick this up Cheers! Capt'n Skunky KSP Community Manager
