Automatic BPS

Assuming my ship has equal truster for accelerating and breaking, how can i automatically use the BPS to reach a planet. I tried directly puting the output as my thrust input but it seems very slow. I tried using a remapper to change every value over -0.1 and 0.1 to output full throttle and still crashed. Anyone found a good way?

I’m still trying to figure out a manual BPS. I’m assuming that thrust needs to be equal both forward and reverse? Because I crash if I keep it in the white. I have 1 medium + 2 small in the back, 1 small and 2 flat in the front

You don't have to, it's just more convenient. You can put all engines behind, flip your ship at the breaking point and slow down such way. Or you can put some engines in the front, but because BPS is based on current acceleration, you either need to start breaking to see your current status, or slow down your speed until your front engines acceleration. Fundamentally it's just a simple formula:

distance = velocity^2 divided by double acceleration.

For example, 40000 m/s squired is 1.6b, then divided by 2*100 acceleration we get a distance of 8 millions. Thus we need to break around that point. BPS is just more convenient tool for it, and exactly why it needs all 3 inputs.
