When trying to upgrade the engine on my Urbanmech, I found that removing the stock engine actually made it gain 2.5 tons and lose all the armor. Is this suppose to happen?

[MechaBattler]

Standard 60 engine the urbie uses is actually an anti-gravity device.

Kidding. They had to make the standard 60 have -2.50 tons to make the stock builds even possible. As for the armor stripping off, I haven't had that happen before.

[Y E O N N E]

Dunno about the armor, but the stock engine has a negative weight value and gaining weight after removing it is normal.

Yes. Engine ratings of less than 100 have negative weight in MWO to account for the added weight of the minimum 10 heat sinks. The Urbie is the only mech in the game with an engine rating less than 100.

Jesus, really?
They need to fix that.

What they need to do is allow me to put 4 std engine into my atlas for extra 10 tons !

They can't...

Engine weights in MWO are borked to be honest..

Engines sub 250 are 1t less then they should be for ever 25 rating under 250, this is to account for the external heat sink you need to mount.

250 = 10 heat sinks, no change
225 = 9 heat sinks, 1t under weight
200 = 8 heat sinks, 2t under weight
ect..
60 = 2 heat sinks, 8t under weight

Technically this is incorrect.

Due to the fact the 1st 10 Heatsinks of a Mech are Technically Part of the Engine it self. This is why there is a Rule of 10 on Heat sinks. Also In CBT the Core Critical Engine Slot in a Mech can house 1 Heat sink for every 25 Rating this Engine Has.

The Gyro and Cockpit weights are also in MWO Engine Weight, Cockpit is always 3 tons, the Gyro is 1 ton for 10-100 Engine ratings, 2 tons for 105-200, 3 tons for 205-300 rating and 4 tons for 305-400.

The Simplest why to code the above is to was to Make the "Rule of 10" for Heat sink than Remove 1 Ton of weight from a Engine for Every Heat sink that had to be placed outside the engine critical Slot. In CBT the Std 60 Engine weight is is 1.5 ton (see chart below). So if we do the math

Engine 1.5 + Cockpit 3 + Gryo 1 = 5.5 tons

With the Engine Rating of 60 (60 / 25 ) = 2.4 round this down to the Nearest whole number equals 2 in the engine housing
Rule of 10 - 2 Engine Heat sink = 8 needed heat sinks.

5.5ton - 8 Heat sinks = (-2.5) listed in MWO.








(Note there is a CBT chart for Engine over the 400 Rating but the Weight Goes up so fast it not until XXL engine are they even Useable (But they use up 6 Criticals in each Torso for IS and 4 for Clans, if Memory serves this OLD pilot.)

Very interesting wolf74. o-o;

I still contend the version in mwo is an anti-gravity device consisting of a cat and jam on toast tied together.

Your Missing a Part of the Moew-Engine system. That is the Carpet Below the Moew-Engine has to be of the Highest Cost if the Cost of the Carpet is to low the Engine Fails to fully turnover.

But back on MWO engine. I think the 100XL was the only one that was out of weight Spec If I remember Correctly when I double Check them a Few Years ago.

Yeap. Basically that is how PGI was able to set the formula to account for the engine heatsinks that in TT are "free weight" but have to be equipped in critical slots. PGI could have setup a different formula and had "engine heatsinks" that were zero weight, with the Mechlab indicating the number of heatsinks to be used but then there would have been the issues of players trying to use normal SHS/DHS instead of eSHS/eDHS. In the end it would have been convoluted and very frustrating, especially for people who never played the TT version or even played BT/MW.

[Radkres]

I played TT when it first came out and the rule then was each engine acted like ten heatsinks before you added heat sinks to your mech but that was a long time ago too.

This is how it should be, but remember that this is PGI we're talking about. They handle Mechwarrior like 343 handles Halo.

That's because they expect you to place your external heatsinks into your 'Mech where you want them. Would you rather it just puts them wherever, and damn you for wanting to move them around?

It's not broken, it's not weird. This is a non-issue.
