Hello. I love making space planes, almost more than flying out with rockets. Cant wait til there might be cloud layers added in the game as well. However, I use two diffrent kinds of tests to benchmark how well my plane designs perform, so it hit me, I could make the shorter test into a challenge to see what other high performing designs other kerbal players might be able to come up with. So here it is. Build plane out of any stock parts even rockets are fine. No cheating in form of custom scripts and engine stacking allowed tho ofc. Use the plane to fly over to the mountains and pass the two tops as the video demonstrates, get back and lans on runway and see how low time you can get when plane stops. Im thinking of deviding this into 3+1 different leagues if there are many trying it: Small jet: less than 250 fuel Medium jet: 250-1000 fuel Large jet: 1000+ fuel Jumbo jet: 10,000+ fuel If you want to partisipate in the challenge it might be best to reply on youtube. But if you like me dislike googles forcing people onto google+ for commenting there I gladly look for replys here as well.
