Hi Cocept30, I have found that if you spend a little bit more on Servos you will have a far better helicopter with far less maintenance, I don't have a Blade 450 but do have two Blade 400 one has been upgrade to HiTec 65MG servos on the CCP and Align 420 on the tail the other to Align 415 on CCP & 425 on the tail I have had no servos issues in three years, PS I also upgraded the Gyro on the older one could not get the e-Flite on to really hold.
