Using CT has the DISadvantage of trimming your nose up as you slow at the top of a loop, or climbs. One of the biggest advantages of the 38 is to NOT have any torque problems the single engine planes have. So looping at 75 knots is easy unless you have the CT on, in which case it will sometimes get "stuck" in the air due to the auto triming. Where the 38 can roll over and hammer the throttle, a 109 would spin on his prop.
