Perhaps time for jet engine rework XD
And tweak smoke particle drag / inertia so the smoke doesn't overtake the craft
New nose cone style that can operate like Komodo capsule

I'm glad to see the Dev team placed some new blades behind the fan of jet engine . However:
1. 'Stator blades' should not spin, otherwise they become 'Rotor blades'.
2. 'Stator blades' should be parallel to the symmetry axis of engine.
3. 'Stator blades' don't need that ring to support each other as these blade are already connected to fan case(shroud) and core engine. Maybe you should paint 'Stator blades' in the same color as the shroud, distinguishing these blades from spinning ones.
Here is a picture showing 'Stator blades' on a real jet engine:

Also the power to weight and power to size ratio of new motor feels much worse than real ones- 400% size, diameter 2m, length 3m, weighs 26.6t, power output 348kW in game (13W / kg).
A real 350kW motor weighs 2511lb(1139kg), length 44.58"(1.13m), diameter 21.22"(0.54m), 307W / kg
It's be better if the propeller starts at feather(parallel to air flow, let's say 90 degrees) position when slider is at 0, so the slider could be used to control the propeller to get forward(10 degrees) and reverse thrust(170 degrees). - Currently the strider prop starts at max forward thrust(10 degree) while only reaching feather(90) and reverse feather(270, not supposed to exist) at max / min slider value. Also props should have connection point on both top and bottom, otherwise the scimitar blade could not face forward when used in pusher config. Looking for turboprop and piston prop too
In current version 1.0.9, electrical plane is super OP compare to jet powered ones in term of thrust to weight ratio, wing load and endurance.

@t4zcomz Landing precisely should be easy if you have a shuttle like craft that can glide or simply put solid booster on a plane(do need heat shield to survive re-entry or with enough thrust to slow down so not heating up). then use parachute / thrust reversing in slow motion to stop rapidly before landing.

I think the jet engine in V0.7.0.0 could be further improved.
1. A new slider in property panel to adjust the percentage of energy that turbine extracts from gas, ranging from 0 to 100%(then use it to drive compressor and fan), which affects core engine thrust and the size of turbine. (It is weird to see a large fan driven by a tiny turbine.)
2. Another slider to adjust energy distribution between fan and compressor, ranging from 0 to 100% and automatically set to 0 if bypass ratio is 0, affecting thrust generate by fan. (compression ratio then is no longer adjustable but would be showed in analysis window)
3. The third slider to adjust burner temperature-an important parameter affecting total thrust and fuel consumption, ranging from 1,000 K to 2,300 K.
4. Add stator blades behind the fan. The core engine of a high bypass fan seems floating in midair in current version, which is odd.
You don't need to match the Inclination of T.T orbit, just aim at 1 of the 2 points where T.T orbit intersects the equator plane, so you can save fuel for deceleration.

Hydrolox do have higher thrust for the same throat size, yet the DV disadvantage seems quite obvious, let alone the price that scales up massively with size. I think the weight and price to size functions do need some rework.

one year agoAt least 1 big engine should be more cost effective than a bunch of mini engines, unless there's reliability concern for only 1 engine.

perhaps use gyro and rcs would help. may need to reduce autopilot pid and keep CoG far enough from CoT
