How To Make Planes and/or SSTOs

@PvPSky I will definitely play around with it but I feel like it's cheating when I have 20000 m/s of Delta V in a small rocket. What do you mean by making part you normally can't through the tinker panel

I mean it’s not really cheating since it’s a Game Feature and meant to be used to make it easier. Plus there’s no Advantage you get over others since everyone an use the Tinker Panel. It also lets you make Parts you normally couldn’t, making the Game more interesting. @Sharandeep981

@PvPSky Thanks but the thing is I don't want to use the Tinker panel as it's like cheating and makes the game easy.

If the Engine Inlet is blocked, replace the Nose with an Inlet so the Engine gets Air. If you need to get the COM in front of COL, try setting the Mass, of the Engine for Example, to 0 using the Tinker Panel found in the Part Settings and increase the Weight in the Front also using the Tinker Panel.

If you have any Issues with not having enough Fuel, make a Fuselage as large as possible (50x50 in front and back, 50x25 on the Sides) and scale it to 5% Size also using the Tinker Panel. Then select the wanted Fuel Type and you have over a Million KG Fuel.
Do not forget to have the Mass Scale of the Block at 0 to avoid any Weight added by the Fuel Tank.

If you need any other Advice, don’t hesitate to ping me.

@Portalmaker And I'll keep that in mind from now on when building planes. Thanks!

@Portalmaker Thanks for the help but I've actually got the plane working from Tully's help and now this is more like helping others who have this problem

@Sharandeep981 Sort of. CoM being forward of CoL makes it aerodynamcally stable in a forward position. If your wings are tipped downward, they generate lift towards the ground. If you could show me a photo of the plane on the runway (preferably from the side), I can help you figure out what's going on.

@Portalmaker I mean if you want to have a controllable plane the front has to tip downwards doesn't it? Because that happens when COL is behund COM

A common problem I encounter when making a plane is that the front is tipped downward, so the wings act as spoilers instead of generating lift. What I'm trying to say here is: Always make sure your wings aren't actually generating downforce!

@Insanity I know I just had 2 control surfaces on the main wing. I got it working now and it has horizontal stabilizers but thanks for trying to help

@Sharandeep981 um it has no horizontal stabilizers

@Tully2001 https://www.simplerockets.com/c/ynBc7n/Testing-Plane Can you access that link?

@ColonelStriker And yea SSTOs are kinda like rockets but there are a lot of changes like you'll probably want to have 2 different types of engines if you want it to be really efficient byt landing on planets/moons without an atmosphere is definitely like landing a rocket though. The main problem I think I'll have with building SSTOs is having enough fuel.

@ColonelStriker For your first paragraph; Thats what I'm pretty sure it is but the plane I'm making Isn't that big and having the jet engine be big enough to have enough thrust or just increasing the surface area of the wings will make the plane look disproportionate meaning I'll have to increase the size of the plane to make it look good leaving me back at square one. I think I have a solve but putting engine on the wing is weird but if I can do that, it'll mean that I have twice the thrust.

Apart from the sliding to the left, I also experience the same problems. But I think the reason is that the thrust isn’t sufficient enough to fly vertically.
.
You see, planes get lift. Which is obvious, but the lift helps reduce the apparent weight of the craft, which is beneficial if the thrust of the engine cannot lift the plane literally upwards. We push the plane sideways to get the upward force bigger using a relatively small force sideways
.
Rockets on the other hand, they have enough force to push everything up easily, so lift forces are now unnecessary.
.
SSTOs (I assume) should be built with a rocket-y characteristics, then just add wings. This way, you can take off with little thrust but can force yourself to orbit using the full potential of the thrust of your engine.

TL;DU/DR: make a rocket-ish craft then add wings. If taking off like a plane, use little thrust, then go crazy when getting into orbit

@Tully2001 It's 21,219kg with the engine and 19,498kg without the jet engine
