[SHOWCASE] Show us your VTOL's


Recommended Posts

id say vtol isn't about sas, though sas is a nifty half ton counter balance. full fuel to empty fuel vtol is about balancing center of dry mass over center of fuel http://i.imgur.com/vCJOqev.png this would be an example of an ssto vtol that stays balanced full to empty since the vertical engines and dry mass are over the center of fuel (i count the fuel tanks behind the cockpit as dry mass since the craft was balanced with them having 0 fuel also they launch dry as well).

though balancing engine thrust between two or more engines is another way of getting around that to a degree

http://i.imgur.com/coaRjCX.png the vtol balance is perfect though the forward thrust is a tad bit high due to the vertical engine being slightly below the center of masses. to fix this i simply cut the thrust on the two upper engines by 10%.

a trick to finding out where the vertical engine's thrust lays is to temporarily cut the thrust of the forward engines. by doing this you don't shift the mass of your vehicle.

applying the same trick to fuel tanks can show you if your fuel is truly balanced as your craft burns. ( COM should remain static at all fuel levels )

TAC fuel balance mod is very handy as fuel lines can't solve every problem.

also the Editor Tools mod can find the dead center of a fuel tank. useful for placing vertical engines at the center of fuel.

*disclaimer, this way of balancing doesn't count for Center of Drag/lift so high vertical speed may and most likely will cause unintended explosions*

and since this is a show off thread~i figured landing on an antenna on top of a building not just once but twice would be a good show of skill and design :D
