Glasgow Class X-03D-Service SSTO

when you lift off, try to go up at 10 degrees, now keep in a straight line until you reach a speed of about 1300m/s and an altitude of about 18k, keep in mind that as you are flying in a straight line, the curvature of Kerbin will make it seem like you slowly pitch up to 20 degrees, this is completely fine and according to plan, when your engines cut out, press 1 and 2 and you will switch to vacuum mode, if you don't do this perfetcly on time the main engine will do this on it's own, this can work but it is more efficient when you do it as soon as the side engines flame out.

once you are in vacuum mode try to follow the velocity vector but make sure that you don't reach your appoapsis and start to lose height, if this happens, pitch up untill you start to fly level again, now keep flying along the velocity vector until you reach a speed of about 2300m/s or until your appoapsis reaches 250km(recommended) or you prefered orbital altitude, you will still be at around 40k altitude, just keep flying throught the atmosphere untill you reach vacuum.

here I have found a video that could help you too: https://www.youtube.com/watch?v=8XI-DwXZm10

cant get this thing above 50,000 meters what am i doing wrong

hey, I changed it, but if you want a cheap version, try the X-03A, its the most reliable and rather cheap version of the x-03 series, at least a lot cheaper than this one :P

Please tell me you changed it after my comment and it didn't say it right here on the page :P Thank you, looking forward to try it, i'm not much of an spaceplane guy myself, but need a good template to get some stuff into orbit without crashing my budget :)

it seems that the missing part is a part from the DLC, ill upload a version without that part

I'm getting the error "missing MonopropSphere" when trying t open, are there non-stock parts on this?
