Vanamonde Posted July 24, 2021 Share Posted July 24, 2021 This is a common problem for new players. KSP wings produce no lift at zero angle of attack. Adjust the landing gear so that the hose is higher than the tail and you'll start to generate lift while going down the runway. Other measures may also be called for but see what that does for you.

I've already did it on start... Small landing gear on back and medium on front. Link to comment Share on other sites More sharing options...
Vanamonde Posted July 24, 2021 Share Posted July 24, 2021 Okay, next suggestion. How fast is it going when it gets to the end of the runway? It's a fairly large plane and might need more speed and/or lift. Link to comment Share on other sites More sharing options...
Admiral Fluffy Posted July 25, 2021 Share Posted July 25, 2021 (edited) Try getting rid of some of the Oxidizer, and get rid of the Monopropellant in the cockpit. Also know that SSTO means Single Stage To Orbit. If that doesn’t work, watch this video on how to make SSTOs. Or try this:https://wiki.kerbalspaceprogram.com/wiki/Tutorial:Basic_SSTO_Design If all that doesn’t work, try to make an SSTO able to reach orbit, and then improve on that. (If you want something stupid, make an SSTO that launches SSTOs.) Edited July 25, 2021 by Admiral Fluffy Added some helpful stuff. Link to comment Share on other sites More sharing options...
Aerodynamic Kerbal Posted July 25, 2021 Share Posted July 25, 2021 Hmm, the lift will be better if you rotate the wings to a higher angle. And maybe you can move the wings slightly forward Link to comment Share on other sites More sharing options...
Dientus Posted July 25, 2021 Share Posted July 25, 2021 (edited) On some of my segmented wing builds, I have to turn on advanced tweakables in the options and I use the "autostrut to grandparent". This keeps the wings from flexing or 'giving' to much. If wing surface area is as large as I see there and its not at the front, I add canards to the nose. Also, if you are attempting to launch with the Goliath engines only, consider binding the rapiers to a key like 1 to toggle the engines on and off. A short burn of the rapiers after initial rolling cutting them off before final liftoff can decrease your total takeoff distance. See if you can get a picture of center of mass and lift. Depends on your design, but try to keep those two balls almost ontop of each other. I suggest having lift slightly behind COM BUT still touching half of it, for your first few builds.

Vanamonde Posted July 25, 2021 Share Posted July 25, 2021 That seems slow for a plane of that size. Does it need to be that big? Link to comment Share on other sites More sharing options...

Vanamonde Posted July 25, 2021 Share Posted July 25, 2021 Don't start KSP with SSTOs, willy. They're one of the hardest things. Link to comment Share on other sites More sharing options...
Zacspace Posted July 26, 2021 Share Posted July 26, 2021 Something I haven't seen anyone else mention yet, that plane looks like it has pretty small/few control surfaces. That combined with how far your center of mass is from your center of lift, I suspect you don't have enough pitch authority to force the nose of your plane up, even at high speeds.

Kerbal Productions Posted July 27, 2021 Share Posted July 27, 2021 For starters, start a rocket, not a plane. Planes are more complicated than rockets, in terms of building and perfecting. So, rockets then planes. Link to comment Share on other sites More sharing options...

Exactly that tutorial I wanted to suggest too, when you start building planes. Based on provided picture we can only guess what is wrong with craft design. With that tutorial and a bit of trial and error you will quickly learn how to design aircrafts. Link to comment Share on other sites More sharing options...
GoSlash27 Posted July 28, 2021 Share Posted July 28, 2021 I concur with the other opinions posted here; rocket science is relatively easy compared to airplanes, especially in KSP. KSP has its own rules for lift and drag that don't correspond to the real world, and it took me literally years to figure them all out. IMHO I make pretty good SSTO spaceplanes, but I can only hazard a guess just from looking at your picture: Your wings are too small, those Goliaths are boat anchors, and you don't have any static incidence built in. That might be totally incorrect, tho'. Best, -Slashy Link to comment Share on other sites More sharing options...
