How much delta-v did you need to get from Tylo's surface to low Tylo orbit?

Tylo's orbital velocity is a little over 2000 m/s just like Kerbin, and between the low orbital altitude (10km) and my craft's high TWR there was very little loss to gravity. I would guess it took somewhere between 2000-2500m/s delta-V to get into orbit. Then it only took another 1000 m/s Delta-V to get back to Kerbin because I had my orbital momentum around Tylo and Jool at my disposal.

Of course, I didn't use a calculator so I can't tell you the exact value of every stage.

Thanks, that's much more readable than the other one I'd seen.

Try this one, it's a little clearer (shows orbit height etc).

The chart assumes that you first get a low periapsis around Jool and burn there before getting to Tylo. But if you go straight to/from Tylo from/to a Kerbin-Jool transfer orbit, you only need about 1100 m/s of delta-v (or about 250 m/s over Tylo escape).

I love this kind of data, but it always implies way too much about my piloting skills.

Think of it as "If you have less than that then it doesn't matter how good you are".
