Rocket cars?

Question

i need help with rocket cars!

I tried to first make a jet car. it was awesome capable of going up to 200 M/S, looked cool oh! it could also fly because of the large spoiler.

i then tried to make a rocket car and failed every time. any ideas? :0.0:

Welcome to the KSP forums @STORMPILOTkerbalkind, you've certainly found a very Kerbal way to get into the game.

How fast were you going when your rocket car failed? At some point it simply won't be possible to overcome even the most minor instability caused by steering wobble before parts of your vehicle slam into the ground. And even if that doesn't do you in, atmospheric heating will probably start to explode things if you aren't using spaceplane parts. At the highest speeds KSP can't even process interactions with the ground consistently.

If you don't mind construction spoilers, this video by Stratzenblitz75 gives you an idea of what's possible.

You are probably going so fast that the slightest bump will cause you to flip out of control. I tried to do this as well with a similar result. This would probably work if you were driving out on the North Pole were it is flat. But that also means you would have to fly your car over via a cargo plane, which can be annoying.

Hence my post in the “Placeable launch sites” begging for this.

Or, given the fact we just want a flat 'lake bed' to run on, Alt-f12'ing the car up there is a completely acceptable method for doing so, even if you are RP'ing.

Should be pretty simple.   Get a fuel tank, add engine.   Slap a cockpit on the front, add some wheels, throw in a dash of downforce, and FFFWWWOOOOOOM  Rocket car.

Welcome aboard!  Can you elaborate on what made it fail?  Did you run out of fuel?  Did it veer out of control?  Did it spontaneously explode? (Hoping it was the latter.) 

Also, what rocket did you use?

Moar Boosters! :)

You are probably blowing up the gears. Use the heaviest ones, I don't think anything else will withhold the stress. And you need some wings with the lift going down to keep the thing on the ground. You probably will need to use the wingtips with surface controls, and trim them to force down (and you will need to relieve some pressure as you speed up to prevent destroying the wheels).

Are you sure you’re not thinking of HyperEdit or VesselMover?

I’m pretty sure you’d still have to drop it from orbit if you use Alt-F12

Quite possibly, but, upon reflection, I believe I saw this in a Manley video.  I think he makes a quicksave, and leaving the game open, he edits the lat and lon (and probably altitude) of the vessel in the quick save, then reloads it.    It will then place the vehicle on the ground on the caps.  I know I've done it with a stock solution, but it's been a while

There's an easy and automated way to do that if you are using 1.4 KSP: Firespitter has a part called "FS3WL Water Launch System" (fsmovecraftgadget) that automatically moves your craft to the desired location at launch.

All you need to do is to create a file with the data, select the file on the part, and voilà. You are there, no mater where (interesting explosions wait for you if you don't mind the colliders).

That part is working on the latest Firespitter. I'm using right now. The 'North Polish" is a preset, by the way. :) 

note: The part works, but the coordinates are completely screwed up on KSP 1.6.1. :/

note2: If using Vessel Mover, turn off damages before moving the craft. The wheels are getting destroyed on my vessel on drop. [You need to use Place Vessel, not Drop vessel. Duh. :P )

With Alt-F12, you generally use some combination of SetOrbit and infinite fuel to get above the destination and then deorbit yourself and land.

Ejection seat! You NEED to build an ejection seat with sepratrons. And if you're not using an external command seat, put some parachutes on the cockpit.

 

Oh, and it might help to turn the gimbal off on the rockets that make the car go swooosh!

Since you only quoted one word of my response, and only posted one yourself, I have no clue what you are trying to ask of me here....
