Gentlemen, Its great to see a really USEFUL post in which we can have a meaningful discussion about this great advance in R/C technology. (Can we PLEASE keep it that way ????)

To add my 1 cent:

I have now flown the 9000 receiver in my BobCat with PST power, dual Duralite batteries, switches and regulators with not a single frame lost, antenna fades vary from just a few to a couple of hundred but control is absolutely solid.

I thought a more demanding application would be my Savex L39 with Wren 44 power because the model is so small and everything is so close together. Because of this close proximity concern, I installed one remote in the wing. Results have been perfect, again not a single frame loss and fades are less than the BobCat with the wing remote receiver consistently showing the lowest fade count. The L39 has ONE Duralite battery with a single 5.4 volt Mini Hobby regulator.

No screening or any other EMI or RF precautions have been taken, except a careful range check, and both mdels have data loggers which are checked after EVERY flight.

My new 9100 is on the bench with Dual A123 batts and no regs but I think I will use regs. and two hard switches to make sure the servos receive only about 5.6 v, well below the 6 v limit. I believe this will be safe for the Rx too as although Spektrum say the op. voltage is from 6 to 10 v the manual also suggest that brown out voltage is way down at 3.5 v and I have never seen a voltage this low on any of my aircraft (all of which fly with volt loggers on board).

For those who have new 9100s be advised that the rx lights blink after a loss of power (simulated by switching OFF and then ON for the batts.) Reconnect is instantaneous, but the blinking lights warn of the power loss, great idea.

I will flight test the 9100 soon in my BobCat XL.
