Sorry Karnak.. my test doesn't agree with Rips. Sea level speed (tested at 50 feet anyway).
Me110C: 289 (no wep)/ 299 (wep- 5 minutes)
Spit I: 283 (no wep) / 291 (wep- 5 minutes)
Doesn't even come close to making the 315 claimed here or the 335 claimed in Rips test. Maybe I did something wrong?
EDIT: Oh, for my test I climbed the 110 to about 3,000 feet, levelled out without WEP, went and smoked a cigerette, came back. Climbed back to 3k, dove without WEP, levelled out and punch WEP. Ran level until wep ran out. Proceeded to kill 2 drones with MGs, and then ran into a hangar trying to fly underneath it inverted

. I'll check out the Spit I next.
EDIT, part deus: Just checked the AH help chart on the 110C.. looks like it matches up pretty exactly to me.
EDIT: Part.. tres?: Added the Spit I. It can outrun Spit I's, not sure about the 'easily' part though.
