For Drone stats and details try, here
There are four main stats on your ship
Drone DPS is exactly like your Offense DPS stat except it responds to your Drones. Drone Control Range determines how far your drones can operate away from you. Drone Bandwidth determines the amount and size of drones you can have in space. Drone Bay is the physical storage of your Drones, like your Item Bay, it is exclusively for Drones.
Some of these stats may not be obvious at first so we will talk about it in a little more detail below.
The other important ship attribute is its “bandwidth” (which you can also check in the Attributes tab of your ship's Show Info window), which represents your ship's ability to control your drones, and is measured in Mbit/sec. Bigger and more powerful drones require more bandwidth, and you can only deploy (i.e use in space) as many drones as you have available bandwidth on your ship. Many ships (particularly dedicated drone ships) can carry many more drones in their drone bay than they can deploy at once; this allows you to selectively deploy different types of drones to best match your enemies, or to replace drones which are destroyed in combat.
However, irrespective of your ship's bandwidth, you can only have as many drones in space at once as you have levels in the Drones skill (up to 5 drones at level V). The only exception to this limit is the very rare Guardian-Vexor, but in every other case you can only ever have at most five drones in space at once.
With the exception of fighters and fighter bombers (which are only used by capital ships), a drone's bandwidth requirements (in Mbit/sec) is always the same number as its volume (in m3). Your ship's bandwidth is fixed, and is not affected by skills or modules.
A ship must have a drone bay to use drones. You can find out if a ship has a drone bay, and how big it is, by looking at the Attributes tab in its Show Info window - if it has a drone bay, it will tell you the drone bay's capacity in cubic meters (m3). The size of a ship's drone bay determines how many drones you can carry with you, ready to be launched into space; larger and more powerful drones take up more space in your drone bay.
The Tristan has a 40 m3 drone bay, which means it can carry up to eight light drones (which take up 5 m3 each), or four medium drones (10 m3 each), or a combination of the two (e.g. two medium and four light drones).
Only drones can be carried in a ship's drone bay; it cannot be used to carry other cargo. While you can, of course, carry drones in your cargo bay (just like any other kind of cargo), you cannot use them if they are not in the drone bay. You can only move drones in or out of your drone bay while docked at a station, or by using a ship/structure with fitting service (e.g. a mobile depot or a Capital Ship). The size of your ship's drone bay is usually fixed (with a few exceptions, such as the Ishkur, whose drone bay size depends on your skills), and cannot be enlarged using modules.
Most Drone stats are fixed, but there are some you may change.
This range can be extended by training skills:
With Drone Avionics and Advanced Drone Avionics at level V, your drone control range is 60km. To increase it further, you can install modules and rigs on your ship:
All combat drones (except the stationary sentry drones) have a built-in microwarp drive (MWD), allowing them to travel quickly to engage a target. Once they arrive near their targets, they shut down their MWD, orbit the target, and fire their weapons. This means that, unlike for the other weapons systems in EVE (lasers, projectiles, hybrids, and missiles), drones first have to travel to the target, and then stay within range of it in order to apply their damage. In practice, this means that drones will have difficulty against faster, more agile targets, as even though they may be able to catch them thanks to their MWD, they may not be able to stay within weapons range for long (at their non-MWD speed). Larger drones (medium and heavy drones) in particular are almost useless against fast frigates for this reason.
Salvage and mining drones do not have MWDs, and therefore always travel at the same speed.
The Tracking and Optimal Range of your drones can be changed:
There is only one module that can increase your Drone Damage
If you undock with drones in your drone bay, you will see a new window for controlling drones appear on your screen. Through this window you can launch drones from your drone bay, give commands to them once they are in space (for instance, to attack a target, orbit your ship, or mine an asteroid), and recover them (bring them back into your drone bay). This window also shows you if any of the drones you currently have in space are damaged.
You cannot control how a drone fights and flies directly; you can only issue commands like “attack that target”, in which case the drone will fly to the target you have selected, and start firing on it once it's within weapons range, all without further input from you. You can give commands to each of your drones individually, or to all of your drones at once. The Using Drones page goes into more details on the different commands you can give to your drones.
If damaged, a drone's shields will slowly regenerate on their own, but damage to its armor and hull needs to be repaired (e.g. by using the repair services at a station, a remote repair module on your ship, or being tethered to a Citadel). Drones have built-in weapons with effectively infinite ammunition, and don't need to reload.
As a general rule of thumb, ALWAYS have your drones set to Aggressive and Focus Fire.
The BOLDED commands may be given to all drones at once by right clicking on “Drones in Local Space” and giving them orders.
There are keyboard shortcuts that allow you to do some drone commands, you may change these shortcuts. The most common commands and their default keybind are listed below
