1. ## How can I make my shuttle more stable?

so I have a space shuttle with delta wings u know the real space shuttle copy, and sometimes the sideway-aerodinamic forces make it spin out sideways uncontrollably. What could i do to make it more stable against drag? I think the answer might would be bigger wings but i dunno...
2. ## What is total delta-v?

hmmm... interesting... can u see somehow how many dV your spacecraft can make?
3. ## What is total delta-v?

In one of Matt Lowne's videos I heard that to go to eloo your rocket need to reach a total delta-v of 4000 m/s. But what this mean? Is this means that that's the max deceleration or acceleration what you'll need to make, or what? He also stated out that his fuel just ran out before reaching that speed. I wanna make some rockets and put some stations on distant planets and an ssto that can send crew on them and back to kerbin, and i was just curious what could this total delta-v mean, and how it could help me make it.
4. ## estimated burn shows lower value than it actually would be.

I know that a burn on full throttle can solve this issue, but the value still stays the same
5. ## estimated burn shows lower value than it actually would be.

I undocked my spacecraft and maneuver node est. burn shows inaccurate value. it shows the actual value divided by 30 or something like that, but thats really inaccurate estimation, how could i fix this? (I also used bracket keys for quick switch)
6. ## How you even manage to rendezvous?

Thank you! this guide helped me a lot ('n' saved me a ton of fuel!) with the help of it, i managed to put another piece to my space station with my shuttle! (in the left you can see the station)
7. ## How you even manage to rendezvous?

i did a hohmann transfer rendezvous but i have no idea what's next... slow myself down to zero at 15,000 m like the in-game tutorial showed? I hate the KSP tutorial because its just complete BS and it works very differently. in the tutorial, your target speed allways reduces naturally, and the prograde marker alligns up with the target marker... i used to slow down to 5.0 m/s and then speed up to 10.0 m/s back-and-forth-back-and-forth until i managed to get close enough but then both craft started to spin like they wanna orbit each other, and drifting away, and dancing around, and i have no idea what to do cuz im tryin' like for 3 days now and i'm frustrated!!!!!!
8. ## How to land a shuttle at KSC?

well, first i bend the spacecraft 40 degrees to slow myself down, then when the map show that i'm gonna "fall onto KSC" i set myself a bit to prograde until my navigation to KSC alligns up to prograde on the nawball. You'll start to descend and lose speed rapidly, but you just need to do a preflaring and you're done!
9. ## How to land a shuttle at KSC?

hey! I tried something before using the mod: I warped until my spacecraft was 90 degrees ahead of KSC, waited a bit, made a maneuver node a bit behind my craft, (so that it needed to circle around the planet), and the planet, the periapsis, and the spacecraft were alligned perfectly!
10. ## How to land a shuttle at KSC?

Right now i have a 110 km orbit, but i have 4 main questions: Where to put the maneuver node, where to aim the periapsis, how high the periapsis should be, and how to calculate with all that to the earth's rotation, and the drag what air makes. I made a test flight earlier on with the shuttle, and then i put the node 90 degrees ahead of the KSC and aimed the periapsis 90 degrees beyond the KSC, but i only used my eye, (just like i read somewhere in wiki) and when i reached the maneuver node, the KSC and the periapsis alligned up just to the right direction, but now, i have no idea how to recreate it again.
11. ## my space shuttle starts to make barrel rolls

well... I've done it but now something strange going on... at 362 m/s its do the same barrel rolling, without touching the controls
12. ## my space shuttle starts to make barrel rolls

do yo mean that the vector of the CoT should point to the direction of the CoM? (i checked it, and its just barely points to the CoM, not exactly to the center) update: i put in some 2.5m fuel tanks to the cargo bay so now the CoT points towards the CoM. but now its too heavy and tilts to its back
13. ## my space shuttle starts to make barrel rolls

It is facing where i wanna go, the problem is that when i use pitch, its also bit tilts to the left, and later it's become uncontrollable (I guess because i dont used symmetry tool to take on the vector engines, because if i would, it would not allow me the thrust vectoring) . but when i dont touch anything, it flies nicely until it reaches 800 m/s, (in the 4th picture you can clearly see that the navball shows that its flies straight, but the vectoring makes it go forward you can see on the navball that i tried to tilt it to counteract the forward motion of the vectoring, and how it tilted to left (for no reason!)
14. ## my space shuttle starts to make barrel rolls

so i built a NASA style spaceshuttle, and when i dont touch the controls, its flyes pretty well... but when i touch the pitch, its starts to tilt to the left.. and then make barrel rolls uncontrolably. also, when i reach 800 m/s, its tilts backward and starts to descend. I tried to eject down SRBs at 800 m/s but there were plenty of fuel on them.... what a waste...
15. ## i need help about my basic rocketry fails

1. drifting: sometimes i just launch a rocket and when i try to make my orbit by turning into a 40 degree its starts to drift (sometimes i turn it at 7000 m, when i want a lower orbit, when i want to visit a planet i turn it at 14000) 2. spinning around the navbal:l sometimes i use struts, but whenever i try, my rocket becomes instabile, and starts to make a delicate spinning around the nawball. this is very annoying because when i try to modify my orbit, its sometimes modify it vertically too. 3.making orbits: my basic method to do an orbit is to fly up to 14000 m, and then turn it to 40 degree. after that, at 30 000 m i turn my rocket to 90 degree. when my periapsis comes out from kerbin, i travel to the apoapsis to make a burn in prograde, and make my orbit "circular". i think its a very primitive and fuel-wasting method, so somebody pls tell me (or take in a scott manley tutor i dunno) how to do it.
