I have successfully flown both F&M and OS metal case transmitters using an Ace TR403A full-range 27MHz Narrow-band AM receiver. I'm guessing this receiver is really a Futaba repackaged.
The Sport Series Kraft used a shorter pulsewidth than standard and I don't know if that would be an issue with the receiver decoder.
If your transmitter is 72MHz and wideband, it's not legal to use. In this case consider a conversion to a narrowband modern frequency.
