Hello! Made an account just to post about this.
I've been messing around with the beta since yesterday, and I love it. It's so cool! Here's some stuff I found while playing.
The landing legs on SS are non-functional. I have no option to deploy them at all. I don't know if they're implemented yet or not, but that's what's happening for me.
I don't know if Retractable Lifting Surfaces is required for the new SS, but it seems to function without it installed.
I've found that, for me, it's easiest to fly SS by assigning the front and rear flaps to 2 action groups, set to Toggle Deploy. For me, that's the easiest way to keep the ship stable during landing.
Do you need to swap the control point to the docking port during reentry? Even with the Pitch, Roll, and Yaw enabled, the flaps barely move whatsoever until I swap to control from the Docking Port.
The flaps also like to actuate into the oncoming wind, which seems inaccurate. I believe they can only actuate to the leeward side.
I've also encountered the strange "opposite torque" thing, where the fins cause the ship to pitch in the wrong direction. This rarely happens, and when it does it only lasts for a few seconds, so it's not that big a deal for me.
I've had no issues with SuperHeavy.
I LOVE the TU shaders. They look so good!
(Idk if this is relevant, but I've only got Tundra installed along with the dependencies + FMRS, and I've uniinstalled Retractable Lifting Surfaces. Running on KSP 1.8.1)
