Neptune Suborbital Hopper

@SaturnaAerospace thanks! I agree, the roll is super annoying lol

@Fyrem0th oh alright, I was wondering what the mass scale editing was about, respect for all that math! Also just a side note, the JNO devs gotta add some sort of “roll lock” thing, kinda like what there is for pitch and heading

@SaturnaAerospace yeah, the reentry tumble is an issue i’ve found too. The reentry RCS have 5 tons of thrust iirc, because the vehicle is so light, ya need really powerful RCS, but i only have them on during reentry, other times i just use the normal RCS AG. Idk what to do abt the skirt burning, cause the plumes aren’t near it. Just a thing i’ll have to deal with. Originally, I had 3 shorter strakes radially mounted on the ship, but remove the third one after watching Everyday Astronaut’s video on why the old BFR design switched from 3 fins to 2 on Starship. Turns out the third strake made roll and yaw control super hard on reentry, so now there are 2 longer ones lol. At least for now, the reentry tumbling isn’t a terrible issue as the rocket has LOX and Hydrogen pumped through its walls (hence the edited max temp), like the heat shield on Stoke Space’s Nova rocket, so it can withstand crazy temperatures. Also, the reason it’s so light is because it’s made of Carbon Composite (hence the edited mass scale. I had to do soooo much math to work out how much i should reduce the mass scale lol)

Aesthetically, this is awesome. I love the color of the tanks and the engine plumes are just 👌. Design wise I found out some things that might help you later down the line. I don’t know how you made it so its roll stays under control, but I need to learn lol. On hops this thing does great, aside from the fact that the engines heat up the skirt a little during the flip and burn. I took it on a high speed reentry flight and it struggled to maintain pitch, as in it spun around in circles. Maybe reduce the size of the aerosurfaces? Overall though, great design.
