@EternalDarkness well then thank you but looks like i am not going to be able to do this because i dont what i am doing sadly well that is what people say but it is all cool thank you for helping

To dtart a challenge, I recommend first posting a build that you'd consider a good entry, so potential participants can see you know what you are doing. Then, issue a set of requirements. For example, "no mod parts, must have at least x parts, must be flyable,...". You specifically state that xml editing is allowed, else you'll get a lot of people asking if they may edit this or that. You issue a deadline. Rewards are usually upvotes. Since winners are likely to have more points than you, I advise against promising spotlights. You may also present a rating system. You can see example of that on my challenges. Oh, and don't just post a cockpit. Try to make a 2d logo or something. Nobody likes a cockpit.
