These are rough tests so give them plus or minus 3 seconds. Parameters are:
Climb speed: 150 mph
Fuel: 100% full
Test Ceiling: 20,000 feet
Climb was from the runway at sea level to 20k. Times are:
Bf 109G-10: 6'10"
C.205: 6'15"
Spitfire IX: 6'16"
Remember, these are rough, but I think it may be an indication that 109 is still 1st in climb to 20k, and that C.205 is comparable to Spitfire in climb to 20k.
