Symmetry tags for different parts types are much harder to implement. When using the symmetry in the game, the wings rotate so the \'top\' faces in the opposite direction. The \'top\' of the wings of the Hope shuttle face in the same direction. One of the wings need to be rotated 180 degrees in Blender and the \'rot\' value needs to be manually edited.

Just a couple of things I have discovered while manually editing .craft files. Instantaneous Geosynchronous Orbit Whenever a craft is launched, the game finds the part with the lowest height position and moves it to the level of the launchpad. Every other part is moved up accordingly. This is why a craft will still launch even if there are parts below the ground level in the VAB. A ship can be put in a geosychronous orbit immediately by exploiting this behaviour. Add a decoupler to the bottom of the ship and change its \'y\' \'pos\' value to -2868400. The game will automatically move the decoupler to the level of the launchpad and the rest of the ship will be moved 2,868,000 m in the air. The ship will inherit the angular velocity of Kerbin to give a geosychronous orbit. Manually Adding Ailerons Currently, ailerons only work if added to a ship in symmetry mode. This behaviour limits wings to having zero dihedral angle and limits ailerons to being the same part type. To manually add ailerons, find the parts in the .craft file to be linked and add \'sym =\' and then the name of the part it is being linked with. An unauthorised edit of sarkun\'s Hope shuttle that shows working ailerons despite the wings being different parts. Unlike parts, the game does not need to restarted if craft changes are made.

Landing values are on the conservative side and rounded up. A sufficiently skilled pilot could probably do Low Mun Orbit <-> Mun in 0.6 km/s. Mun -> Mun Transfer Orbit includes the delta-v required to intersect Kerbin\'s atmosphere. Travelling at Munar escape velocity still requires a second burn.

A rough delta-v map of the current solar system. Values may be on the low side due to the Oberth effect. Not a particularly large map since there\'s only two bodies to land on.

I had most of the submarine already modelled. I had messed around with buoyancy before, but put the project on hold since I couldn\'t figure out a good way to control depth. Your proof-of-concept was the \'missing link\'.

Your dumbbell model is missing a collision mesh. From the blender tutorial: A collision mesh The collision mesh sets the shape the game uses to calculate collisions, and where parts are allowed to be connected. The game only uses one collision mesh per part, so only use one object in your model. Add a new object via 'Add:Mesh:' then selecting the shape of your choice (usually a cube or cylinder). Select the object (right mouse button by default) and then go to 'object' then rename it 'node_collider'. Remember to add a material and UV co-ordinates to this object also!

Finally stopped being so lazy and released the Modular Missile Pack. Gets around the issue of decoupler weight by having the main missile body act as a decoupler. Comes with a couple of different nose cones and some different fins. Allows for some variation in design so every missile won\'t look exactly the same.

Implying that this is a beginner course. I would make an easier track but the 2km part size limit makes it difficult to create large, sweeping tracks.

Released a new version with some ridiculously strong struts that holds the parts together. Solves the part wobble problem.

The engine still gimbals even with the typo, it just changes to a smaller, default gimbal value. The current value works perfectly fine, so I don\'t think a change is really necessary.

Updated the first post with some stuff for use with the C7 flight pack. Forward swept wings with built in ailerons and a Mk2 hull bicoupler part.

While making that slalom course, I found that all the parts have to fit inside a 2,000 m cube with the centre at the origin. The game automatically scales down any parts larger.

Is editing the .craft file so the wings have a positive angle of incidence considered cheating?

The ultimate in weapons of mass destruction, the Jupiter class nuclear-powered ballistic missile submarine is highly moble, virtually undetectable and offers any country first strike, second strike and decapitation strike capabilities. Comes equipped with ICBMs. A roughly 1/4th scale of the US Ohio class nuclear ballistic missile submarine. Measures around 42 m tall and 4.3 m wide. Top speed is 40 knots (~20 m/s) with an endurance in excess of 1,000 days at maximum power thanks to its nuclear reactor. Usage notes: [list type=decimal] [li]Use the .craft files provided. Creating the sub from scratch in the VAB is sort of complicated. [/li][li]In the provided .craft file, there are two solid rockets in either the first or second stage.

While I don\'t doubt that flying a magic turbine requires skill, it\'s not really in the spirit of the competition. It looks like TheMattyPrince is winning the free section and WhiteOwl is leading the standard section by default.

Finally managed a 3 orbiter craft after several attempts. It has a total of 95 fuel tanks and 33 engines although further optimisation could reduce this number. I initially tried to design a craft that could land on solid ground but after seeing Technical Ben\'s water lander, I decided to go for three water landings instead. You don\'t have to worry about engines breaking off or finding flat ground to land on and the altimeter displays the exact height above the ocean.

Fastest... :

Landing would be the major problem and that is an exercise left for the reader.

[list type=decimal] [li]The node collider is too large and is colliding with the object it is being attached to. Reduce the size of the collider or turn allow collision on.[/li] [li]All the rotational values for \'node_attach\' are all zero.[/li]

Fixed it. Seems it only affected the \'right\' facing gun. Are building up a stack on another node before moving them to the gun?

Added some sideways firing guns, just for you.

Good luck flying this thing. It has a tendency to fall apart on the launch pad and shake itself apart when airborne.

The problem is the weight of the standard radial decoupler. The decoupler stays attached to the missile so the missile\'s thrust isn\'t directly over the center of mass and that causes the missile to curve. Increasing the missile mass would help but that means less missiles can be carried. Increasing the lift generated by the fins would also work but that would unbalance your craft. Attach the missile to the decoupler near the nose of the missile so it pitches away from your aircraft when fired.

Yep, crash into the VAB to finish. Videos aren\'t really necessary, but pictures would be nice.

Inspired by the thread on KSP\'s most experienced pilot in General Discussion; what better way to separate the excellent pilots from the good pilots than with a race, so I present the inaugural Kerbal Air Race Championship.
