0 time challenge completed.

I tried to do better time but while doing so design gets more complicated and final result is that vessel is very unstable. I wanted to make design similar to yours but also have seated kerbal to save some mass.

Here is mine entry, 8 sec on splash down. I might try faster later.

I limit using large tanks and engines that so vessels do not look too similar because mission is quite simple. Coming back from Mun without using a heatshield and parachute makes it more challenging because you can't just re enter atmosphfere with high velocity and if you do you won't be able to land with damage. Limitations are reason to see different ways of doing the same thing.

Because it is a challenge with made up story.

Infinite fuel is not allowed of course. I will add my entry soon.

Mission info: Race to establish base on the Mun rages between Nasa, SpaceX and Russians. Kerbals have decided to use their engineering skills to arrive first while in process Jebediah has forgot to bring any food. Your mission is to create vessel and go to the Mun to bring them some food until they start growing plants. Summary: You need to land on the Mun, drop "Service Bay 1.25" , plant a flag, return and land on Kerbin as quick as you can. Time stops after touchdown and flag plant on Kerbin. Rules: Only stock parts. External command seat is not allowed Kerbodyne and Rockomax fuel tank and engine class is not allowed No boosters Only 3 stages are allowed (not including service bay separation) Vessel should not take damage on landing You cannot land on engine nozzle Heat shield is not allowed Parachute is not allowed No infinite fuel _____________________________ Take a screenshot or two and if you can share a video or craft that is cool. https://kerbalx.com/

Maybe you should define track limits since laptime from Colonel Cbplayer looks like he is cutting all corners

TR-2L have a good grip. Yeah with top speed you can flip car very easily so car design and aerodinamycs are important.

[quote name='Jon144']I have a question: Can you not use any stock wheels at all? I might have a new fancy rotor/wheel design coming up.[/QUOTE] Sure build something and show us. Also show which wheels do you use. For championship I want it to be stock because of simplicity for everybody and to make it more fair. ksp 1.1 will have edited wheels so we start from there. I am doing some laps with new test car [spoiler=car][IMG]http://i.imgur.com/R3oZqIm.png[/IMG][/spoiler]

[quote name='GROOV3ST3R']Thanks :3 Cubic struts are brilliant for sculpting neat looking spaceframes and they weigh next to nothing :3 500kg would make a small difference but it would count ;) How do you count weight then? With RCS loaded or empty? Because that counts for a lot. I'll go and get mechjeb for 1.1 after it's released.[/QUOTE] I am using MechJeb because it is more precise. (1.000t) Mass is counted like in total - car with full rcs tanks and seated kerbal. (2500kg total or 1766kg without fuel 640kg and kerbal 94kg). Today I have spent few hours testing things and it is interesting. No kerbals were hurt today :wink: I hope for 1.1 asap :) Btw try to beat my laptime in this challenge so I can try to go faster.

GROOV3ST3R I am using MechJeb Vessel info to measure mass. Mass is measured including all components. For the championship that will include 2 fuel tanks with fuel, seated kerbal in cage. Also we will have to make some crash tests to see if kerbal can survive. :D :confused: Working on a test model with two FL-R10 RCS fuel tanks [spoiler=test model][IMG]http://i.imgur.com/ADzPQgb.png[/IMG][/spoiler] Cars definitely won't be any wider than this [spoiler=Car width][img]http://i.imgur.com/5NATOpf.png[/img][/spoiler] We will see about mass if we maybe lower it for 500kg. When v1.1 comes in I don't think it can make a big difference but just make it better. My results won't count to make sure I am not making rules for myself. :)

[quote name='Pds314']3 tonnes minimum? Let's see.. 200 kg of wheels. 50 kg of pilot seat, 320 kg of RTG, 80 kg of lights, 370 kg of monoprop tank... So what, do you expect us to devote 1980+ kg to structure and thrusters? Making a car that heavy is not easy. Also, it is worth mentioning that you could probably go all-out for a whole lap with 10 thrusters.[/QUOTE] Then use 10 thrusters. :) In this challenge you can do it more easy without aerodyamic drag but for the championship this will be fixed with limited vehicle size. Add some cool parts to add weight but keep your car balanced to stay on the track. :D If we use TR-2L on less than 1t car you will flip it on the straight. Point of all of that is fast cars , challenge to build one and of course right strategy to drive and use fuel.

[quote name='GROOV3ST3R']Here we go again... xD I do prefer the regular rover wheels to be honest, they have more in terms of actual suspension and are MUCH smoother than the MK2's. There's reasons why we limited Kyrian GP to using them. Other than that, 3 tons is a bit much :P my old racing design barely pushed 1 tonne dry. I'll give it a crack though.[/QUOTE] Yeah I was looking a lot about designs so I wanted something a bit more challenging. Since M1 has some grip issues and strange steering I have chosen TR-2L which offer good grip and fast responsiveness (responsivness can be simply edited with car design) (we will have new wheels in 1.1v so it will be interesting) I can simply limit car width so you can't use very wide cars to keep stability and go without wings for no drag. Key will be to make well balanced and stable car for cornering. With more heavy cars there will be also more fuel and more complexity and creativity with designs (like a real formula k). With all of that a lot of parts can be used so cars won't look all the same. I think this will add more strategy into play. Seated driver will ride car. But sure I would like to hear what do you think about that.

[quote name='Azimech']When it's ready ;-) When multiplayer arrives, I'd like to have my own racing team. Let some people drive while I build the cars.[/QUOTE] Nice creations on kerbalx. Multiplayer would be awesome for many things but I am not sure how warping will be synced. I have been working and testing a lot designs and rules for championship so base is ready. Now I hope that update arrive soon so we will see what happens next.

[quote name='Gaarst']Pushed water physics and SAS to their very limits with this thing, that went up to 263.0 m/s ! Unfortunately, it is extremely unstable at this speed and always ends up crashing into the water. Best I did with recovering it in one piece was around 220 m/s. Will do another run with more screenshots.[/QUOTE] This is very interesting model. I might give it a try.

[quote name='Azimech']This will be an interesting challenge after 1.1 has arrived.[/QUOTE] Yeah there will be some changes about wheels and traction so it will be interesting to see. Does anyone know when the update should occur? This is fun challenge to see some designs and prepare for the next one. I have been speaking with Kyrian a little bit so maybe Formula K championship gets alive again.

I was landing on the Mun when suddenly on touch down rocket almost flip but then stayed balanced on two legs like this :D. Question is now do I turn SAS off? [IMG]http://i.imgur.com/GXSbgEK.png[/IMG]

Nice try littlebuddy0. TR-2L wheels offer a great grip so it is important to have a good balance for fast cornering.

video from old challenge, only with bill kerman. with more fuel by the end of runway speeds could be greater

I guess there was like 50 challenges like this one posted in last 2 years

Here is my entry- 39 seconds lap. With this car it is possible to make 2 seconds faster laptime. Further design and riding improvements could improve probably a lot.

First shots of my car. I am doing 40 seconds laptime but still looking to improve design and driving

Welcome to KSC untimate race challenge! Objective is to build the fastest car and make the fastest lap as you can! Rules: 1.
