are you talking about the Hisky FBL100 or the Turnigy FBL100? If it's the Hisky....that heli looks "cheap" enough that it probably won't work without it's own particular Tx. If you are talking about the Turnigy FBL100, you may have to get in touch with Hobby King and ask them, but I do see FHSS on the Tx that comes with the heli and I think that the FHSS is Futaba. That being the case, this heli probably won't ever work with a Spektrum Tx.
Sorry buddy!
