I just did the math and such (read: BT nerd) If you want the Highlander to have a boosted Jump profile, it needs at least a 360-rated Engine, and even then, its maximum speed will only be 64 Kph, with a maximum jump distance of 120 metres (30 metres per jet)<br/><br/>Of course, a 360-rated engine is stupid-heavy (IIRC, it's around 33 tons, while a 270-rated, what the Highlander defaults to is around 13 tons), so in order to fit one, you need to either A: strip 20 tons of weapons and armour, or B: get an XL engine, and strip 3.5 tons. 5.5 if you want the 4th jump jet. Swapping an LRM-10 in for the -20 saves a total of 5 tons, so the Highlander's overweight by half a ton.
