RoboCorp Presents: Return-IV

[Robo336]

After much research & development (also known as trial and error) RoboCorp has developed a ship capable of landing on Duna and returning the crew safely to kerbin.

And now, the journey in pictures:

At this stage, it is possible to set the trajectory for aerobraking useing very little fuel

Hello.

Don't worry about the stranded landers. We'll come back for them... someday... maybe... not...

Main trajectory set.

Fine tuning complete.

Aerobraking.

We're Moving too fast! Activate all engines!

I must be doing something completely wrong, as I can't even get into Kerbin orbit with this....

I lift off fine, separate the SRB's, then things start to go wrong. If I dump the empty fuel tanks, I lose control and spin out. If I keep them on, I'm too heavy, and can't get high enough for orbit. Also, I can't turn 90 degs for gravity turn at any point, as I just don't have any control.

Can you give some pointers on how to fly this big boy?

Thanks!
