RE: JR 921 receiver question
The R921 originally came out before the low voltage firmware update. So it is possible to own a 921 that was not updated. However, if it was purchased from Horizon in the last year it probably is updated. It is easy to findout the status. Just power the transmitter and receiver. Then briefly unpower and then restore power to the receiver. If the receiver lights blink after power is restored, it has the update.

Power up the transmitter and reciever and wait for it to link up.
Turn off the receiver and turn it back on. One of three things will happen.
1. The reciever will connect instantly and the lights will flash. This is the newest firmware.
2. The receiver will connect instantly and the lights will come on steady. This is one version out of date, could be updated but it will work.
3. The reciever will take 3 seconds to connect and the lights will come on steady. Send it to Horizon and get it updated.

The R921's (and I have several from the first batch Horizon got) came with the original Quick Connect firmware which was actually announced with the AR-9100.
The original version had the fast recovery time but did not have the flashing light indication that a power brownout had occurred. That option/update was announced about 5 months after the first R921's came out. My first AR-9100 also came with the original Quick Connect firmware even though those didn't ship until about 2 months after the current version of Quick Connect was announced.
So I sent all of my 9 channel rx's in for the update along with all my 6 & 7 channel rx's when Horizon offered the free update which was about 9 months after the initial R921's started showing up. I actually got my backorderd spare R921's about 2 months before Horizon started shipping the first X9303's.
