I'm using an old-but-good Thunder Tiger Raptor 50V2 as a test-bed for my new Spirit2 and can't find the 'pulse' and 'frequency' values for the JR DS821 servos for cyclic. I have a faster Futaba S9254 for rudder. Can anyone suggest values for the DS821 in the setup wizard please?

The Raptor uses mechanical mixing for cyclic and I assume it's ok to select 'CCPM 90 degrees' for this, although the 'Servo Connection' section of the wizard - and the swashplate diagram - has me confused with its allocation of servos to the swashplate. Any help or guidance, please?

Many thanks, Andy

Unfortunately mentioned cyclic servo is not suitable for FBL helicopters. It can be still used, but with poor performance.
You will need to set 1520us and 60Hz.
Higher frequency could work but servos can overheat.

For flybar helicopter it will be still fine.

Yes, CCPM 90 is correct.
