Wing vector question

@Zaccurus damn this is good information.. I Will try this guide Asap because for now i combine jet engine with aerospike that make the plane super heavy with 2 type propellant

@Dracozard It's fine if the center of thrust is at the back as long as the craft handles how you want it to. A fighter jet has its center of thrust at the back. The center of thrust is naturally at the engine, as the engine is the source of the thrust. You may have to counter the weight of the rocket engine at the back by moving the primary wings further back or by adding mass to the front of the craft, or both.

@Zaccurus im trying make a Ssto with aerospike engine, that make Center of trust Way too far back AT the engine, i think i Will try make it fly atleast, but for now i try make a simple plane to understand the indicator do for every part i move or change. Thx @DPSAircraftManufacturer @Zaccurus

@DPSAircraftManufacturer It's a good basis for planes that get their lift and pitch/roll/yaw control exclusively from the wing part rather than things like RCS nozzles or custom wings. Those things can make the blue indicator misleading as I don't think the game takes them into account when calculating where it displays the blue indicator, even though they can influence the center of lift greatly. There are exceptions, but most fixed-wing aircraft handle best with the center of lift a bit behind the center of mass, unless the center of thrust is way at the front or extremely powerful or something like that.

@Zaccurus wow thx for the explanation, i never play this game before so i still need figure a lot of things, thx for help

@Dracozard Generally, you want the blue indicator (center of lift) to be behind the red indicator (center of mass) for the craft to be flyable. If the blue indicator is in front of the red, then the craft will pitch upwards uncontrollably. If the blue indicator is too far behind the red, then the craft won't be able to take off at all. You can change the position, size, and shape of the wings to change the center of lift, and add or subtract mass from the craft to change the center of mass. The yellow indicator (center of thrust) should be centered on the craft's x-axis, or width, so that the craft flies straight.

@Kell @DPSAircraftManufacturer So what the 3 indicator Center mass do? The Red, blue and yellow one, what i must do with the Center mass information?

You fly test it @Dracozard

@DPSAircraftManufacturer oh wow, thx for the reply, u help me alot.. And the last questions, how i know that my wing big enuf to generate lift? Example if i build big plane, how do i know that wing is enough for lift entire plane?
