If I am going to connect via an USB Simulator Cable, which should I select to (usually there is a selection like FMS, XTR, G3 G4, Aerofly, PheonixRC, etc.) ?
the best signal quality has the RX2SIM from RCWARE. This is the adapter which is offered also as bundle with neXt. For example, when you use the RX2SIM with an Futaba transmitter, you have full 4096 steps per channel. Very precise !!!!
The signal quality of the cheap China adapters is very poor.
