OK, that was a crap analogy.
The point I'm making is that energy weapons seem attractive because they seem so light and compact...but I'm starting to realise that they aren't at all.
I will often pass over cannons because they seem far too heavy and bulky for their performance. But it was only after working on my 'Ninja' design that it occured to me that the savings of space and weight I believed came with energy weapons are all completely in my head.
Y'see, when I choose a Heavy Laser over an AC 7, am I really saving space and weight? Umm, not really. Despite the fact that the AC7 is 2 tons heavier and each slot of ammo takes up 0.5 ton.
OK, let's take Weight first.
Now the Large Laser is going to need 2 PU more juice according to the instruction manual (IIRC).
Depending on what Powerplant you're using, that can be anywhere from 2 to 11 tons extra weight.
Can you say? EEEEEEK!!!
Also, take into account that Energy weapons tend to heat up much more, although I believe that is more to do with their faster firing than anything else.
Also, take into account the space those engines take up. Admittedly it's not often as severe as anmmunition, but it can be a big problem if it lives insufficient room for armour. A big engine housed in the Centre Torso (most vulnerable servo to attack) with thin armour due to space restrictions can turn an expensive titan into a walking firecracker!
So these days, I am considering that if I'm going to be serious about designing walking tanks, I oughta stop snubbing cannon weapons so much and embrace the guns that fire da ammo!
Just make sure you include a DCS in the design. Ammo explosions are friggin' nasty! Also, I must admit, the range of most cannon weapons is better than most energy weapons.
Hand me some words, will you, Whitefirefox?
*munch, munch, much*
Mmmm, bitter!
