A choke servo probably is a better choice, in this case.
Whit an FM or PCM receiver a choke servo will be vulnerable to RFI and may shut off your engine when you least expect it. The same is true of an Optical Kill Switch which may experience a false signal due to RFI in the receiver. At least it will not pick up any noise through the switch cable (which acts like a virtual antenna).
Well, if you place the servo at least 6-8 inch from the motor, use nylon push-rod and assure no metal contact in the setup, a choke servo will no cause RFI. Have been using this setup on three gassers with PCM rx. No problem at all.
As I said before; As long as there is no source of RFI you should be fine. If there is RFI generated by the engine you could mount your servo or receiver in the tail and will get hit anyway.
The risk of RFI should be eliminated by a range check. With correct setup, RFI is not a concern.
With a choke servo, the ignition circuit is physically isolated from the receiver component.
