Do I need to adapt my Starship for PC mods?

@KraZIvan
Starship now has a 8000 ∆V

@Insanity ah yes youre right

@KraZIvan dv for LEO is more like 8000-9000m/s

Presumably if your craft has enough Delta-V (5500 I think) to reach LEO, you shouldn't have to modify your craft for RSS. However if you're on the RSS sandbox, I would highly recommend Realistic Engine Overhaul as @sflanker suggested, since the goal of RSS is to increase the game's realism, using REO takes this one step further and lets you design engines that have stats closer to their real-life counterparts

@sflanker
I'm using it but it will be mobile Friendly because I will make a video how to use RSS on Android

Most rockets designed for Droo and the default solar system won't perform very will in Realistic Solar System because of the increased size and mass of the home planet, plus the increased distances between the planets and moons. You'll want to look at Realistic Engine Overhaul when making rockets that will perform well in RSS.

That said you don't "need" to make these adaptations if you're not using the modded solar system yourself.
