I've been following the PTS forum for awhile now, and I realize people are interested in the new weapons. I have haven't seen a post about the weight of the LFE yet.

Some of you may not have noticed yet, but light engines are about 80% of a standard engine. If you thought that sounded odd you'd be right. According to Sarna it's supposed to be 75% to be exact.

Designed to mimic the compact profile and light weight of Clan-tech XL Engines, the Light Fusion Engine weighs only 75% of a standard Fusion Engine. While not as dramatic as the 50% weight saving of an XL Engine

I can understand that they'd need to round up, but that shouldn't take up an additional 5% (especially after doing the math). An easy example being the Standard 195 Engine it's 10 tons being lowered to 8t with the current metrics, where as it should be 7.5t. While that doesn't sound like much, let's up the engine. If it were a Standard 375 Engine weighing 45.5t with the Light Engine currently 36 tons. According to Sarna however, it should be 34/34.5 tons if rounded down/up.

So, what does everyone think of how Light Engines are currently being implemented?

I believe you are forgetting gyro weight in your percentage calc.

[ViridianDrake]

Just so you know, the gyro is listed in the mechlab as "Fixed Equipment" just like the cockpit, life-support, sensors and actuators. It doesn't appear to actually weigh anything outside of the mech's default 10% total tonnage. (without endo, ofc.)

The engine weights are going to be off in MWO, as MWO calculates engine weight + Cockpit+Life Support+Sensors+Gyro-Heatsinks<10

. Below is the actual BATTLETECH ENGINE only numbers, and not just for STD vs LFE vs XL.

Cockpits - All are 3 tons regardless of mech weight
Gyros - engine rating/100

blank Oh look, 400 engine rating XL 26.5 tons, LFE 39.5 tons and STD 52.5 tons

BATTLETECH 300 engine rating XL 9.5 tons (50% lighter than STD) / LFE 14.5 tons (looks like a 5 ton difference there!! and 25% heavier than XL) / STD 19.0 tons

MWO 300 engine rating
XL- 9.5(engine) + 3 (cockpit) + 3 (gyro) = 15.5 tons
LFE - 14.5 + 3 + 3 - 20.5 tons
STD - 19.0 + 3 + 3 = 25 tons

All the math works out to be exactly the same as tabletop Battletech, you just have to DO the math first.

1 - Start with a MWO standard engine.

2 - For engines under 250 rating, take the engine tonnage and add the tonnage of the extra heat sinks you need to buy to make a total of ten. This is +1 ton for engines 225-245 rated, +2 tons for 200-220 rated, etc.
2A - For engines 250 rating and over, skip this step.

3 - Now subtract 3 tons for the cockpit.

4 - Next up, Gyro. Subtract 1 ton for an engine rated 100 or less, subtract 2 tons for 105-200 rated engines, 3 tons for 205-300, and 4 tons for 305-400.

5 - you now have the true weight of the engine itself. Multiply by 0.5 for XL engines and by 0.75 for Light Engines. Note how many tons you just shaved.

6 - Go back to the listed MWO weight for a standard engine (step 1), and subtract the tonnage saved you found in step 5. I think you'll find the published MWO tables to be accurate.
