Very sorry for your losses guys.

I think a lot of the losses that have occurred with JR / Spektrum have been due to poor current flow, low voltage issues.

I still see a lot of guys using standard plugs to supply the power into their rx's. These plugs are only rated at 3 amps. That's just not enough current flow guys. You are going to have limited current flow and voltage drops when using standard plugs. Why risk your jet?

I still see inline switches being used. A lot of these inline switches are only rated at about 5 amps.
I also see batteries being used that are not up to the task, and undersized wiring, etc.

You can't suck an orange through a straw.

One of the best new products that have come to market recently is the Powersafe rx's that JR has (the R1222 rx, the R922rx, the AR9100 rx).
These rx's are great. They provide 2 HD inputs for current into the rx, and they come with a failsafe switch that is not an inline switch and does not limit current flow in any way. I highly recommend these rx's.

Other options are Power Expanders, PowerBoxes, or similar components that provide for proper current flow.
You should chech the manufacturer ratings of each and every component you plan to install in your plane and make sure it is up to the task. All it takes is one weak component to cause low voltage or limited current flow.

As mentioned above, these 2.4Ghz rx's are extremely sensitive to low voltage. While you could get away with a set up that provided limited current flow and voltage drops on other systems (72Mhz, 35Mhz, etc.), you can not do that on the 2.4Ghz systems.
