Flying to Mars using TransX

[Omegaham]

Alright. I'm a reasonably experienced pilot, and am now trying to figure out how to do interplanetary travel. I can
manipulate my orbit well, I can dock with the ISS and land on the Moon, but I can't make that leap of going from Earth to Mars.

I've tried using TransX, as it seems to be a lot less complicated than IMFD. However, I can't figure out for the life of me
how to put the plan into action. I can fiddle around with the prograde velocity, eject date, and plane change, but I can't
figure out how to actually burn it. When I actually attempt to do so, it produces a hyperbola that takes me a few gigameters
off of the target.

Any help would be appreciated. Thanks!

It's almost impossible to do it without at least one course correction midway somewhere. Once all is set up you then
need to follow the plan. You do this by burning at Periapsis until you acquire the needed deltaV to reach your target.
There's no real easy way to figure when this is. It depends on the power of your engines. I usually just eyeball it and guess
how long a burn I'll need then divide that in half and start that many seconds before Periapsis. Seems to work for me. There
is an MFD however that can take some of the guesswork out of it. I think it's called "Burntime MFD".

This is why I like IMFD, because burn time is calculated for you, but it has it's drawbacks too (too many ships in a scenario
ect...)

If you post the scenario where you have just completed the burn leaving Earth (trans Mars injection) I would be happy to take
a look to see the plan and how close you are on the planned trajectory. I might be able to offer some assistance.
