HI Again

There is no end to the various levels of backup systems U can have.

For me it comes down to weight / Performance and costs.

Yes U can run dual receivers and I do on my 40% and larger Models. I find receiver failures are infrequent so I choose not to backup that system.

Attaching a setup of my personal 3.3M CARF Yak. I could have even added backup Batteries for the Primary Batteries for that what if scenario U guy's are discussing.

Last is my small workshop where I do final assembly and repairs on these machines. The Extreme Flt Yak up front is 87 inches for size reference.
