Infinite fuel? 🤷🏻‍♂️

You can crank the engine power to about a megaton, and then only use 1% throttle. Lowest fuel burn ever.

Yes, you got it @atgxtg

@LiamW So I'd have to double the power output to offset the input reduction?

So if I wanted to turn a J15 engine into something 1/10 the size, power and fuel use I'd have to:
Scale Mass and dimensions (check) then
Scale Input to 0.1 (10%) fuel use
Keep Power the same (1/10th original power times ten to offset the input scaling equal 1).

0.5 input, 1 thrust, 0.5 mass will give you an engine with half mass, half thrust and half fuel consumption. Half input means you will only ever reach half of the maximum normal thrust @atgxtg

It's a jet, a tiny one (13.5x8.8x4.4). It flies fine, too. It's just that it's supersonic at sea level, and I thought it would be more realistic if it were a bit slower, and wanted to put a less powerful (and thus less thirsty) engine it it.

@atgxtg You should be able to mqke the engine as powerful as you like. Is this a propeller or a jet?

@F104Deathtrap Thats what I did, but then it couldn't take off, thanks to the weird type of landing gear I'm using (hemisphere). Usually the hemisphere works nearly as well as wheels, sometimes even better, but the lower throttle input means the engine can't overcome the initial friction -so I guess I'll have to stick with a fuel guzzler.
Kinda makes sense. Anybody who can afford to buy a single person microjet probably ins't all that concerned about fuel economy.

@atgxtg You can bypass consumption by multiplying the thrust (or horsepower) and then decreasing max throttle input. The only downside there is the engine becomes excessively quiet.

@F104Deathtrap Thanks. Luckily that didn't happen, but I shot myself in the foot another way. After reducing the thrust I naturally had to adjust the wings to fix the trim and such. So after spending a bit of time fiddling with the wings to get it flying nicely again, I put it on the ground and discovered that it no longer had enough "oomph" to actually get it off the ground. So I had to keep the Input at the higher setting after all.

@atgxtg Be careful about modifying the mass of any moving part, especially rotators and engines. You run the risk of the parts becoming glitchy. With engines, the bug cause the plane to shudder and the propeller to move forward and sometimes explode. Doesn't always happen, but it does happen.

@LiamW So if I set an engines to .5 mass, .5 power and .5 input I'll get one half the weight and thrust, but which burns fuel at half the normal rate? But wait, input is set to Throttle.

So far everything I've tries to change adjusts the thrust, but the fuel consumption is the same.

EDIT: Okay, I scaled down the max to 0.5 on the INput Controller Settings and the PowerMUltiplier to 0.5 in the Engine settings and I think I got a pint sized J15 with half the size, mass, thrust, and fuel burn.

Thanks everybody!

10x power and 0.1 input creates a regular power engine with 10x better efficiency. Reducing the input reduces fuel consumption

Yes. Don’t know how to use 70% of it. XD. I have the google doc thing. @jamesPLANESii

Boi do you have Overload? @Caveman999

Adjust the max input of the engine.

Ok. Also remember to tag me next time. Your lucky I looked on here again. @atgxtg

I know I can change the mass in Overlord, as well as the power. Changing the power isn't necessarily unrealistic. First off, not all jet engines have the same thrust to mass ratio. The F-100 Engines on the F-15 have about 3 times the the thrust to mass ratio of the earlier J-47 engines of the F86.

Besides, if I scale the mass in half I should scale the thrust in half just to keep the TMR the same.

1. I’m not sure.
2. I’m not sure if you can change weight
3. Yes you can change the power. It is very unrealistic though.
