Kieren, bleeding E has nothing to do with turnrate, radius etc. After 1 full circle with 4-5 G you´re near a sustained turn with every AC here in AH. The spit has maybe a better sustained turn, but will loose speed quicker if you start to turn from higher speeds.
climb to 10000ft (100%fuel), dive down to 450mph at sealevel, when you´ve slowed down to 400mph begin a constant 4G turn - after 360° turn the mc205 will come out with ~260mph, the spit with 220mph (use trim to hold 4G).
accerlate at sealevel to 300mph and repeat the turn with constant 3G- the mc will leave the circle with ~210-220mph, the spit with 180mph
Don´t believe it? test it. Takes only 15minutes to do it!
