Having lots of fun with this one. Might be as close to an A-10 Warthog as we can get in MWO. The XL250 engine propels you up to 124.4 with full speed tweak. The 1st time taking it out even without the RAC enhancement skills I ended up with 1 kill/KMDD (Atlas) and near 500 damage.
Quick reminder that an XL255 weighs the same as an XL250, just a heads up so you can squeeze some speed and a heatsink into the engine!
For the cost of one JJ, I'd take the bigger engine. I feel like the JJs on this are just for snap turns and getting over small rocks, not vaulting over mountains.
