Another use with squishy hinges acting almost as leg muscles on a mech suit:

tried using KAL controllers for animation for the first time

I think it would be roughly the same difficulty because the ore percentages are the same. The burns would just be significantly longer which is why I chose a lighter comet.

The idea is that you'll use BG robotics parts. Fuel cells, solar panels, or RTG's should ideally be good for power generation for sustained flight.

Construct an ornithopter capable of sustained flight. Rules: No lifting surfaces can make a full rotation on any axis. No engines (engine thrust) allowed. Breaking Ground is probably really helpful but pure stock is allowed as well. Mod submissions (if any) will get their own category File-edited or overclocked submissions (if any) will get their own category No Alt+F12 Submissions: No submissions I haven't actually created a working ornithopter but I've been trying. If I get a working prototype I'll post it here.

Went biking. No reaction wheels, steers like an actual bike. It also weighs 278 kilograms and consumes only 0.05 EC/s.

Could be because I used green monoliths to unlock nuclear engines and then I sent Jeb to Eeloo and Dres. but that's a stock feature I dunno

Same I had no idea. When I heard of "alternate launch sites" I always assumed it referred to desert launch site or island airfield. Then one day I was looking for green monoliths and was like HUHHH??? I love easter eggs

The speed loss could also be because you seem to be driving west (orbital direction) on an equatorial route (about 30° N) at a high altitude (orbital navball). As you speed up, you negate more of your orbital speed so the NavBall reads a lower value. Just click it to switch to surface speed.

Tank in Stock KSP. (+breaking ground) It is incredibly accurate, destroying targets while moving up to 600 meters away. In theory it can hit targets even further away but I didn't really care to test it. The main issue I run into is the fact that the bullets move too fast for the collision detection to sometimes register, although on bigger targets it's not really a problem. The iron sights also work decently well for targets where target tracking isn't available. I could consistently snipe the R&D dome right in the middle from the runway. The setup should also in theory be able to hold a perfect target lock even if the rover itself is bouncing around on rough terrain. While I'm driving the rover in the video I'm making minuscule adjustments to the command chair angle based on where the bullet goes, so that they are all almost perfectly dead in the middle of the target.

Similar to @Lisias I also made a potential solution plane for the reddit guy making SRB planes, although I scrapped his design completely. I made what is basically an early-career C-172. It only costs 65 total science to unlock the required nodes. It is also marvelously easy to fly. I haven't crashed (this version) once, and its descent profile allows for pretty significant course corrections for precise landings. I tried to make the aerodynamics and "flight feel" match as closely to an IRL Cessna as I could, although the switch from a prop to a jet definitely increased the cruising speed. I've flown Cessna's in real life so that's what I based it off of. 30m/s takeoff/landing speed 90m/s cruising speed 30° ascent angle 5°-15° descent angle ~900 km range (?) One important difference is the lack of throttle input during the descent. The Juno engine has a much slower throttle response time than a Cessna propellor, so I decided to just eliminate throttle and control angle of descent with flaps only. Here's a video of me flying to the Island Airfield. Landed perfectly first try, didn't even make a quicksave that's how well this plane flies. Descent begins around 5:50, landing at 9:40.

Here's the latest and greatest: Completed stock Orion Drive: Fast mech (latest generation):

IIRC you'll also need to uninstall the DLC's. My run got marked as DLC even though I didn't use any parts or mechanics from them. Edit: Actually, other people completed the challenge with DLC installed and didn't get marekd. IDK why mine got the little green star lol
