Dr_Pockets Posted January 19, 2012 Share Posted January 19, 2012 When I make my own plane and place rudders and elevators on the wings. My planes often have trouble with rolling to either side. Any ideas/suggestions? Link to comment Share on other sites More sharing options...
Goddess Bhavani Posted January 19, 2012 Share Posted January 19, 2012 Rolling to either side is usually encountered due to issues with wing loading. One wing or the other stalls causing loss of control. Mind posting a picture of your aircraft? The good forum should be able to give you some tips. Also, try keeping your plane simple at first, use straight airfoils (no anhedral or dihedral), and with no payload. Gradually evolve to multi-engine designs and exotic airfoils.

Dr_Pockets Posted January 19, 2012 Author Share Posted January 19, 2012 This is one example of one of my planes that cannot roll. I have multiple examples of other planes if you want/need them.EDIT: I feel like it would be a good idea to say that the elevators on the wings do not move when I am pressing the roll buttons.

Goddess Bhavani Posted January 19, 2012 Share Posted January 19, 2012 Great! Thanks for posting a pic. For functional ailerons I have only seen that once on the rare instance I was able to use the symmetry function to place the control surfaces. Other than that for heavy bombers and such I use the rudder to control roll. For a small ship like yours you probably won\'t need 4 huge control surfaces - normal surfaces will suffice and if you want added maneuverability just use a pair of canards on the front (Eurofighter style). Right now for roll control probably you will want to lengthen the nose with 1 fuselage module, and add a bigger tail with moving rudder. Lengthening the aircraft;s nose will make the centre of gravity move forwards making it more stable (will not roll out of control suddenly), while the rudder will add better control authority. Remember, planes can\'t turn without rudders. (B-2 Spirit and other flying wings are exceptions, they have ways to get around the lack of a tail which we can\'t).If in doubt just add an ASAS module in the front and use that as a fly by wire system while you troubleshoot the aerodynamics.Finally, I am very sure you have a small plane with big wings. Too big for an engine of this size. Smaller wings would make troubleshooting easier, though I like the Mirage IV look Link to comment Share on other sites More sharing options...
White Owl Posted January 19, 2012 Share Posted January 19, 2012 Control surfaces in this game function differently, depending on whether you had symmetry turned on or off when placing the control surface parts on your vehicle.Symmetry turned on = ailerons. One control will move up while the other side moves down.Symmetry turned off = elevators and/or rudders. Both controls will move in the same direction.

Dr_Pockets Posted January 19, 2012 Author Share Posted January 19, 2012 Ok, thanks White Owl and pandoras kitten. I just now learned the difference between ailerons and elevators. Thanks pandoras for the plane building help, I will need it in my future KSP plane building. And thanks White Owl for the control surface knowledge. My problem has been solved now.

Goddess Bhavani Posted January 19, 2012 Share Posted January 19, 2012 Awesome info on the control surfaces - I actually crashed and deleted my only bomber prototype with working ailerons. Lol! Link to comment Share on other sites More sharing options...
