The saito 125 will be ok for the funtana but if you want real fun then get the saito 1.50 or 1.80. As for the radio the optic 6 is good but since the Funtanax100 has dual elevator servos(I think) you will need something like the Futaba 9CAP which you can get for $250 at
www.servocity.com. I had the U CAN DO 3D 46 and I loved it. Even though I have never flown a funtanaX100(I have seen them fly) I would recomend the U Can Do as your first 3D plane.
