craggy turtle
for a period of 3 weeks i had great success with single stage to orbit craft, including craft that were no longer entirely focused on functionality, sometimes even having decorative pieces. then, recently, for some reason my SSTOs are not working at all and I can hardly get past 340m/s despite using the same crafts. I have always played stock and never with any mods installed.
generally i am asking for help with a duna ssto (mine is based off of the one used in lowne's tutorial)
On its maiden flight, it was able to get to orbit with barely enough dV to land on Minmus, at which point it would refuel in order to get to Duna, though I speculate that it is theoretically possible to have enough to directly burn, aerocapture, and glide to the surface of Duna without refuelling. For some reason, now, I am incapable of even reaching orbit with enough dV to rendezvous with a tanker craft, let alone get to another celestial body.
The craft is identical to its original counterpart, which is currently stranded on Minmus as it has no ore tanks (something that I am hoping to fix in the subsequent version)
i in general need help with SSTOs because i like them so much and want to use them

have u seen vaos on youtube

I second the above, check out Vaos, he has several SSTO/SSRT tutorials
craggy turtle
still this doesn't explain as to why my SSTO can no longer reach 400m/s
no external parts were added (nothing that sticks out of the cargo bay or nothing that is outside of the cargo bay) and the TWR is still above 1

does changing the variant of the RCS blocks change the amount of drag that they generate?
i really need the 5-way thruster but i am afraid it would cause so much drag the vehicle would not be able to move
craggy turtle
please help me
my plane is flipping backwards
it has a center of lift behind the center of mass and i am not pointing at any excessive angle
and it just keeps flipping backwards
does changing the variant of an RCS thruster really change drag that much
craggy turtle
i also didnt learn anything from it
thin fox
make sure the root part isn't the cargo bay, it can sometimes cause the stuff inside to create drag
craggy turtle
the mk2 cockpit is the root part, not the cargo bay
i got to duna now i need to land

Is your payload heavy? You also might just want to add some more boosters
craggy turtle
the payload is like 3 tons counting kerbals and cargo
quartz pumice
the payload is like 3 tons counting kerbals and cargo
if you have no payload does it fly well?
craggy turtle
it flies extremely poorly without the payload and constantly flips into retrograde
the craft also in general has a tendency to flip into retrograde despite the fact that its center of lift is behind its center of mass
i dont see why it would matter since the payload is not detachable, and it consists of various science experiments and a convert-o-tron which the entire operation of the vessel centers around
i was able to get to duna and i am attempting to land on ike
still the flipping into retrograde after only pointing more than 5 degrees from prograde is super annoying and lead to 54 failed landing attempts on Duna before a single success
and takeoff took 5 attempts

this actually does matter because i need the 5-horn thrusters but i dont want to lose valuable delta-v

sounds like center of mass is behind center of lift
craggy turtle
the payload cannot normally be removed so the center of lift is behind the center of mass but not too far back

@craggy turtle bro, your intake, change it to the shock cone
craggy turtle
i would do that but i dont want to make the ssto look worse
glass finch
@craggy turtle how about keeping those intakes and just add 1 shock cone
(1 shock cone can provide enough air for 6 engines)
Like right at the tail and attatched to a monoprop tank
craggy turtle
woah i didnt know that i will do it in the next version and then send it tolaythe thankyou
glass finch
Good luck with a new SSTO bro
One more thing @craggy turtle
I don’t see any LOX tank on your craft
2 nuclear engines are not enough
Thrust
craggy turtle
they were enough to get me off of duna and the mun but i dont know anything about laythe
and i use the adapters to hold all of the oxidizer
glass finch
Your vertical stablizer is kinda small tho.
Make sure to make it straight up
Ah yes, and a monoprop tank
You gotta need those RCS
craggy turtle
actually the tank in the middle just behind the payload bay is monoprop
glass finch
Oh I see

Where you playing in sandbox and set your gravity or something to some weird number the first times you used it
craggy turtle
wait does this mean i have to redo the whole mission
i swear i think i didnt set it strangely
mind you the ascent was done half on RAPIERs and half on NERvs

no i did not change gravity and i do not change gravity for any of my missions even though i play in sandbox

hmmm idk then
