From what I have read so far, Futaba is not recommending the faast system in jets. Their advertising shows all types of aircraft being flown with the system except jets. I believe if you check the Futaba support forum, the question was asked about using it in jets and it was not positive. I hope this changes in the future as the 12 FG looks pretty good and I'm sure the new JR with the Spektrum will be great also except it will probably cost 25% more than the 12FG
