Ion Thrusters
I've been playing around with Ion Thrusters and come to the conclusion that they are really only good for precision flying like for docking or adjusting to reach ores in or around an asteroid. Or when building a small drone.

As for forward and backward thrust, Hydrogen Thrusters are the go-to method.

Does this sound right?

They are weak for sure, but remember hydrogen burns very fast.

If you have a good generation/storage setup, they can be run for free unlike hydrogen which requires constant mining.

Depends on how you play. From a personal view, I would say that is 100% wrong. Hydrogen takes too much fuel to be useful as a general (non-transport) type of fuel. Some key pieces you are missing are whether you are in gravity/atmosphere.

On the earth like planet, atmo thrusters are the most efficient as hydrogen takes a lot of fuel to keep running and ion has little thrust. Atmo thrusters do not work outside of the planets atmosphere.

In space, ion is used for general work as there is little to no gravity to overcome.

Hydrogen works regardless of gravity or atmosphere (or lack of either), so they are well rounded. However, the fuel (ice) input is pretty steep. Using this for general work is ill advised unless you want to spend most of your time gathering ice. Which, depending on your layout/setup, could be an easy task.

I typically only use hydrogen to get from earth to space as transport. I use atmo on planets, and ion in space.

I'm only using the Ion in space. I've been using them on utility ships, and they work so well with those. As for fighters, not so much.

When it comes to Hydrogen, I use Splitsie's advice. Do not fight against the speed limit. Helps with preserving the fuel.

I fail to see how I am 100% wrong. I went back through with more tests on how the thrusters work. The acceleration on the Ion Thruster compared to the Hydrogen Thruster is, for lack of better words, ♥♥♥♥. If I were to build a mining ship, using Hydrogen Thrusters would cause me to overshoot just from quickly tapping any of the direction keys (W, A, S, D keys). While doing the same with Ion Thrusters, allowed me to damn near perfectly align the ship. Which is why I used the word precision.

When building a fighter, I would want to have a much higher acceleration to get to my target then what an Ion Thruster can provide. Now, when it comes to docking to refuel and reload, I would want to make sure I can do it as efficient as possible. As in, not overshoot the Connectors. Thus Ion Thruster would be used. Hydrogen would cause me to constantly adjust the ship in potentially all the directions. Not exactly efficient, and would most certainly cause one to waste fuel.

I understand I failed to specify the type of ship I was referring to, but still. Precision is still accurate. As for the rest of you post, who said anything about planets? I've reread what I wrote, and not even the slightest hint of any kind was mentioned about designing a ship to fly within a planet. Instead, I specifically said Ion Thrusters, as in a ship used in space. I find it hard to believe that people try to use Atmospheric Thrusters in space, or an Ion Thrusters on a planet like the Earth like planet. I figured that would fall under common sense.

From all the videos, workshop items, I have not seen any small grid fighters that use Ion Thrusters (except when overloading the ship with those thrusters) did not performed well. The maneuverability is horrible, and I would hate to fly a ship that couldn't avoid incoming rounds. I'm not sure how you fight in the game, but a head on assault is a bad idea. Fighters cause more damage when assaulting like a wasp, or hornet of some kind. Fly in shoot, retreat, and then repeat. Not just going to fly up and sit there and shoot. That's a good way to waste resources.

I've notice a lot of people don't bother to consider how their post come across. But yours came across as if I have no idea how things work in the game. When I do. I don't want you to think I'm being an ass or anything. That is not my intent. I took into consideration what you said, and I do appreciate your opinion. Just saying that it came across the wrong way. I had to read everything you wrote, even though 3/4 of it doesn't pertain to my post, to understand what you were trying to say.

I have two types of builds: combat and non-combat.
For combat ships, I use both thrusters, though with an emphasis on Hydrogen. During combat, you really need as much acceleration as you can get, and the hydrogen thrusters fit the bill here. But the ship isn't always going to be in combat, so the use of hydrogen is a waste. So outside of combat, I rely on ions to get around. But during combat, I use both.
For atmospheric designs, I reverse the above. The emphasis is on Atmospheric thrust, but I do have hydrogen thrusters to boost performance during combat.

For non-combat ships I just stick with ions. They're much more efficient in terms of fuel usage, and I really don't care too much about how fast or slow they accelerate.

Does this sound right?"

I use Hydros as "Booster" only, to help when full load and be able to return home (miner ship) , I turn Hydros ON when exiting the planet Gravity, help speed in combat, etch ...

Depends on what you are doing/creating !? and the best Engineer Tip I can share is > I test different concepts to gain XP and find a working solution.

"It is only by testing and trying different concepts that I find solutions"

Use the "Save as" and change the save name to create a testing copy > NEVER mess with your original saves when testing.

I agree. While designing a ship, more specifically small grid fighters, I found Ion Thrusters just simply don't cut it in terms of the combat aspect. While just maneuvering, Ion Thrusters make it much easier for everything, except for combat. Personally, I like to align the connectors as even as possible.

However, while I was playing around with the Ion Thrusters, I was trying to build one with just Ions. My thinking was maybe I could design an effective way to avoid using hydrogen. But nope.

I have seen plenty of designs using both types, I just haven't tried for myself.

Hydrogen gives that kick you usually need to leave the atmosphere of planets. It also goes from 0 to 100 a lot faster with the same number of thrusters making it ideal for long distance space travel.

This explains what was going on in my head perfectly. While I was using the word precision mostly literally, it was implied to have leeway in the meaning.

I love trying different methods and combinations just to see how everything will react with different builds and environments. So much fun, and at times humorous.

I actually haven't been using the "Save as" while testing. So far I haven't run into any problems, but I will now. Thank you!

Boy do I love speed. While the old saying of faster is better may not be true, it sure is fun. Watching high speed crashes in the game is just so satisfying.

Cool, I use the Blueprint feature a lot when I am creating, well I Blueprint before doing any new changes = this way I can paste back in the previous Bp :)

I like space ship more than the others, I prefer to play in space and IONs are my Fav, I have a lot of ION space ships.

Thanks, I am working on this one since 2014, it is very well done now :)

I only have one utility ship in my survival at the moment, which is a miner. But I'm not even using it for that. It's mostly just transferring resources to and from the Earth like planet. It uses Atmospheric and Hydrogen Thrusters.

In my testing world, I have a bunch of different types. Just now really testing different ways to use Ion Thrusters.
