While you build an improved rover, also replace the wheels with the medium ones. The small wheels are far too slow to be useful. Also the use of that 100% anomaly detection rate of the Rovermate is marginal at best. To scan any reasonable area you have to send the core to a high polar orbit, and then follow the satellite for a long time as it goes over all places.

Is there electrical propeller design that can fly (indefinitely) on Eve or Laythe? I still don't understand how these designs work.

The Kerbus Aerospace Division's K-350 is a plain, good, workhorse supersonic regional jet that transports passengers from one city to another, efficiently and economically. It takes off at 70m/s. With a little help from the afterburner to push it above the sound barrier, it is capable of cruising at 640m/s at 11400m, in dry mode. At cruising speed, fuel use is extremely low -- about 0.08 units/s, and the K-350 can fly 3000+ km with 506 units of fuel carried on-board. The K-350 is one of the first commercial airliner with space-grade autopilot technology integrated. The prograde lock function is enough to keep the plane cruising at the above speed and altitude mentioned above. The advanced probe core can even fly the plane by itself, without a pilot! Safety features of the K-350 includes a space-grade parachute. Last but not the least, the cost. The low parts count of 29 and reliable Panther engines makes maintenance easy. For all the good things the asking price for a K-350 is just 18,987,000 Kerbucks. Even for a small regional jet, it is a bargain, let alone a supersonic one! https://kerbalx.com/TheFlyingKerman/Kerbus-K-350 Note: 1) AG1 = afterburner on/off, AG2 = deploy flaps ===================================================================================================================== What airliner can you buy for 10,000,000 Kerbucks? You get a Kerbus Aerospace Division K-210. A fully featured truboprop, carrying 24 passengers. The K-210 is equipped with a full set of control surfaces, strong retractable main landing gears, and combined with <40m/s stalling speed, makes it easy to land even in small airfields. Thanks to the optimization by Kerbus engineers, the two small Juno engines is enough for the streamlined plane to cruise at 290m/s at 6000m, with a >900km range. For 10,173 Kerbucks including fuel, what more can you ask for? https://kerbalx.com/TheFlyingKerman/Kerbus-K-210 Notes: 1) AG2 = deploy flaps, AG3 = deploy tailfins 2) always use flaps when taking off. This ensures the plane taking off before the tail hitting the ground. 3) for emergency landing set the tailfins to 100% and glide down.

In my experience the mini refinery would not overheat if used well below its capacity (say 2 drills and no engineer).

It is just me? IMO the big rockets (anything 2.5m or bigger) are way too cheap. That's why you see people simply throwing moar boasters. The trick is you first do a Mun orbit, then a Minmus orbit, then a Minmus landing. The Mun landing goes last.

How about putting the test item inside one standard faring? Then the drag is constant. IMO a plane or SSTO is the best way to do any atmospheric contracts, though.

I claim my challenge complete!!! The rover is totally stock, the only change to the game is this terrain detail tweak. https://forum.kerbalspaceprogram.com/index.php?/topic/39814-default-terrain-quality-without-most-of-the-lag/ It consists of 18 parts: A HECS probe core, a nuclear generator, 2 Z100 batteries, a reaction wheel, 4 cubic struts, 4 wheels, a chair, a lamp, 2 16S antennas and a resource scanner (for position readout). The whole vehicle is just 0.774 tonnes. Delivered to Minmus by the R-4B rocket (really just 5 SRB's strapped together) Landing on Minmus. The driver, none other than Jeb, had landed earlier (note the the other craft). Rover ready for action! As the sun was setting in the west, the journey began. From my landing location at the west edge of the greater flat, I drove NW up the plateau, then drove west, to the great flat, crossed to the SW corner, then crossed the low plateau to the lesser flat. I could drive 45-56 m/s for most of the trip. Ballistic motion was common, but with using prograde lock, I always land wheels first, and the rover is light enough not to overstress the wheels. Going steep downhill to the lesser flat. A second crash. Looked like Jeb was really shocked. He couldn't walk. I drove the rover at him. He made it back to the rover. Then he tried to leave the seat, and bounced 120m up... Thing got back to normal after that. I crossed the southern edge of the lesser flat, then up the mountain range separating the lesser flat and greater flat. The sun was setting in the EAST. It was difficult to find my way in the dark. I had to stop and waited about half an hour for sunlight. After reaching the top it got better, though. I could see the greater flat, even in total darkness. I plotted a straight course downhill. The mountain is gentle and smooth and safe to drive. Finally reached the SE sector of the greater flat. Almost home. Full speed ahead--57.5 m/s, on the greater flat. Crossed the finishing line! I reckon the trip took about 3 hours. Not too bad.

Can I still do this challenge? My rover Progress so far

Relays can be expensive. For example, this one consists of 16 RA-100 dishes, giving a rated power of 800G (the level 3 DTS is only 250G). So I only sent one into geosynchronous orbit opposite to KSC. Its shadow is covered by a ground station near KSC.

Lots of good replies thanks. I tried @Scarecrow 's tweaks and the plane handles much better at low speed. I can land a little below 60m/s. I also gave the Aeris 3A a few test flights. It is even better. I think my design can be improved? @JK_Kengineer My problem is the opposite. The plane is too sensitive and erratic. If the level is a little off the progade vector drifts to one side. It is hard to align because the craft refuses to fly straight at where the nose is pointing.

I have built my first aircraft that looks flyable. I can fly it off from the runway, make course changes, and fly straight and level at over 900m/s. If there is a large piece of flat land, I can usually land it, flying at about 80m/s and sinking down a few meters per second. However I have no idea how can I land it back to the KSC runway. I have tried placing a few flags along the runway to help aligning, however the plane does not seem to do small turns well at low speed, and I am always about 100m off. I have provided my craft file. It is a problem with my design or my flying technique is wrong? https://kerbalx.com/download/craft/35656
