Kind of an ambiguous question.  I spend more total time on rockets, but I don't build or fly many aircraft.  I can build a rocket, pod to clamps, in a half hour, unless I'm having to scrape for that last m/s, but I  usually need several hours to get an airplane that will fly stably.  Of course, this is with FAR in RO...

Even with FAR the aerodynamic model/physics system is so limited that I loathe making aircraft. It's fine for simple things like a rocket, but making an aircraft is just awkward.

 

The big problem I see is that most people here make aircraft that are basically "rockets with draggy wings", very high TWR (far above 1), dynamically unstable (often even statically unstable) and no way to get off the launchpad other than by "hacking throught rotation wheels". A real aircraft has a 0.2-0.4 TWR, and fighter jet 0.8-1. (almost) All upwards force is due to lift, the engine is just a means to overcome the drag of the wing not to "get up there".

One can hardly blame others though, where in real life we use supercritical airfoils to get the aerodynamic center (and perform better near mach 1) further back for delta wings I don't even know the pressure distribution given the parts of ksp. And that's just for static stability.

 

A common unstable mode I see for crafts in ksp is the longitudal phugoid. (You drop down by having the nose go down, then as you gain speed your nose goes up again, losing speed making the nose go down, and the "wave" you hence make will grow instead of diminish without user input. To cancel this the elevators and trim surface are ever so important. Not only the size/position but also the way they are attached, in "hands free" some craft are stable when the elevators are in a fixed position. Other designs are stable when they are in a free flow position where they can rotate freely around a hinge and follow the air stream. And if they are in a free flow position the hinge point actually matters ever so much: is the hinge/rotating point before or after the aerodynamic center of the elevator

 

Oh and then we don't even talk about high lift devices: modern aircraft really can't function without those, the landing and take of speed would be so high they would need runways a magnitude higher than we have now.  KSP doesn't even have those, all my craft have ran off the runway before getting anyways near nose up moment.

 

 

No without wind tunnel tests, actual design choices instead of just visual cutesy. Design for form instead of design for function.

Yeah I mostly design and fly rocket based missions. Probably 85% rockets and 15%planes. However I answered planes, as the question was ,what do you spend more time on?

Might be different for other people, but for me , building and testing takes way longer for planes to be mission ready than rockets of similar size/complexity.

Gonna break the mold and say helicopters. Find those really fun.

I have I think messed around more with planes, but if I have to actually do something and go somewhere, rocket time. But thats relatively rare. And I do also like making reusable stuff, which lends itself more to planes and things with wings.

Also a bit of time on Rovers... I include planes in rovers most of the time as I tend to build rovers that can fly (especially on larger worlds, like Eve/Kerbin).
With the new shielded rotors and hinges, I might revisit some flying car concept I once tried and failed.

But mostly rockets.

I spend most of my time in Notepad++ working on my KOs scripts, but after that it's rockets :D

Come to think of it, I've never seen anyone launch a HTOL spaceplane using kOS. Is it especially difficult?

Depends if it flies. Mine are capable of it.

(With a few rockets strapped on however.)

What, no slot for F1 race cars?

... and what about Drag Racing?
