I have finally made the switch from 72 to 2.4 using the Hobbico JM912 FASST JR Module and my 10x radio with Futaba receivers. I have about 10 flights on it with no problems. If you are looking for a cheap transition to 2.4 with frequency hopping and you like your JR radio I highly recommend this solution. I may even buy another 10x radio as a backup.
