Transplanted from the RB sub forum. Most are made in 0.90 and will be updated in the future.

Hello everyone and welcome to this presentation of our line of products! They can be used on KSP without any mods because they're all stock!

We have transports in almost any size! Some tiny as your hover car, others the [B]size of an asteroid[/B].
All versions have RTG's and a full spec drone core.
They can be extended in range using auxiliary fuel tanks and booster engines,
They can be used as tankers for any liquid or gas.
They can be used for any cargo.
And they’re great cruise ships too.

[spoiler=general operating manual]

Launch profiles:
Not all ships have the tanks filled to max at launch time! Check in advance the Δv needed after reaching orbit and if fueling is required. Not all tanks have automatic crossfeeding, therefore a fuel balancer is recommended.
Before launch, choose the main probe core as the controlling part. This is mounted beneath the RTG and next to the cockpit (easiest visible from top). Default the cockpit is chosen but on most ships this part is mounted at an angle. In case of the 74, 75, 76 and 78, choose the docking port in the nose. Failure to do so will result in control deficiency and increased drag during launch.
Atmospheric drag on most of these vessel is huge. Keep in mind with every change in direction.
The launch using FAR:
Enable RCS before launch.
Keep Q beneath 5000 Pa. Turning with Q >5k will most likely result in a loss of control.
75, 76 and 78: Start gravity turn above 25km.
The launch using stock Errordynamics:
While launching, keep speed reasonable. Accelerate to 65 m/s then throttle back to 90%, back to 100% above 15km.
Subtle steering in the atmosphere. Be wary of large sideslip angles.
A note on the parachutes:
It is very important to note that these ships are not designed nor capable of landing except on bodies with a very low gravity like Minmus, Gilly and Pol, on a minimal slope. They are not designed for atmospheric flight after reaching orbit.
The use of the parachutes is to help point the nose in retrograde direction if an atmospheric re-entry should occur. Even with maximum TWR, engines at max thrust and parachutes deployed, a crash landing will occur. With the nose pointed in the right direction, loss of life can be minimalized.
When landing on a celestial body, a max. touchdown velocity of 0.5m/s is recommended. The stress of impact at a higher velocity may damage the structural integrity of the superstructure and the engines beyond repair.

This is a lot of work, some numbers may be wrong. I'm constantly refining the designs and more designs are coming, like the 77I-77, space stations, shuttles, cargo, etc.

[B]And a new generation of the whole family with more power and delta-v![/B]

These are incredible in design and functionality, there shouldn't be a problem building communities on other planets with these. :cool:

Thanks :-)

Unfortunately we'll have to wait for 1.1 to really use them again, part count is at 0.90 level.
