Hover engines

Hover engines are often times the prefered type of movement on omni's due to the fact they can hit high speeds but they have the cost that they need something to push off of unlike other engine types. They can hit a max speed of infinte without wing panels but builds with them usually max out around 10k with good skybounce.
Though they can not be ghosted for a full engine, they can be ghosted for drag.

Rocket engines

There are two different rocket engines used for movement the normal rocket engine which isnt used due to the fact the acceleration isnt perfectly linear which ends up causing flinging or even nan problems. While the bigger and stronger super rocket engine is the golden standard for most other builds such as the gyro, og and balljoint due to its near perfect linear acceleration. They are usually better stacked in one place rather then spreaded out especially with the ghosted varient.

Angled rocket engines

Angled rocket engines are just as the name says a angled rocket engine. They use roblox physics to increase the maxmium speed at the cost of a lower acceleration the current most used angled rocket angle is 60 degrees; This is why they are often used in combination with normal rocket engines to maximize both stats.

Ghosted rocket engines

Ghosted rocket engines are rocket engines with no collision or visbility and therefore no ability to take damage. They are achievable by doing a blast radius of 3 on a tnt.

Hybrid engines

As the name says hybrid engines are engine designs that use multiable different types of engines including ones that might not be listed here such as magnet engines or conveyers.

Usual designs youll see are ghosted rocket engines + hover engines to get the best of both worlds (acceleration and speed)
