These units can be used with Spektrum Futaba JR and Jeti. Lots of different options also can be done with them. Dirk at PcificRCjets.com has allot of these in stock ready to ship. The price is around $400.00 depending on options you buy. The sequencers cost about $50 each depending on how many you need to use. So by the time you order a spektrum 20 channel receiver and a cortex pro its about the same price. Its clearly a ton cheaper then a PB system.
