I need help with attaching space plane payload

[max_42]

my issue is the payload will separate and explode under acceleration. turns everything into space debris, when i open the cargo doors they float out.

its a big-s shuttle style space plane. everything uses stock parts only using tweakscale

the lander is attached with a docking port jr , the probe is attached inside the service bay with a sepratron

how do i reliably attach the lander to the plane, and the rover to the lander?

i am only in my 2nd month of playing. i have not quite figured this game out yet

Strut your payload in the cargo bay

Strutting the payload into the bay is the answer - the struts will automatically disengage themselves when you decouple the lander from the docking port. If the idea is to retrieve the lander later, you'll need to think of another solution - such as additional docking ports on the sides of the payload. Otherwise, you'll have unavoidable floppiness (and a strong potential for splodiness) all the way in. Getting those in the correct position is tricky but rewarding if you can manage it. And if you don't have to redock the lander, then struts are all you should need.

How heavy is that lander? It looks awful small to be going in a Mk3 Cargo Bay. Also, the wheels of that rover clipping into the lander might give you some trouble later on - have you tested that deployment design on the ground on Kerbin?

To echo, struts. A single docking port is too flexible, and your cargo will wag around - you want at least 3-4 points of support for stability.

the lander and probe is 4 ton

struts worked perfect thank you very much

the lander and probe is 4 ton

I figure that's a 2.5 meter Service Bay in which you're housing that rover. If it's a 1 meter Bay, at four tonnes you could get away with a Mk-2 sized plane easily. I'd still recommend testing the deployment before going too far out with it, but in the meantime I'm glad we were able to help you out.
