Hello, everyone,

I would like to use the Spirit in a T-Rex 450 with Graupner DES servos.
Swash plate DES 488 BB MG
- 4.8/6V - 26/31Ncm - 0.09/0.08 sec/40° - 26/31Ncm
- Neutral pulse: 1.5 ms
- Max. Control frequency [ms / Hz]: 3.0 / 333 ms / Hz

Tail rotor DES 4477 BB
- 4.8/6V - 14/15Ncm - 0.05/0.04 sec/40° - 0.05/0.04°F
- Neutral pulse: 1.5 ms
- Max. Control frequency [ms / Hz]: 3.0 / 333 ms / Hz

These servos are not in the servo list.
Is it possible to operate these servos on paddle or FBL head?
Please give me a short info.

Regards
Dirk
