The issue you are asking us to address has nothing to do with the order the Aircraft and the TX are turned on other than with no signal from the TX first, the heli runs the risk of "going mental" from outside radio signal interferance. If you loose the signal at anytime, the heli is more than likely going to crash rather than fly off into the sunset. How would you keep the heli from flying away if the TX signal is lost anyway? You no longer have control. Your question is confusing.

The issue with turning the TX on first is that you are transmitting a signal which is hopefully neutral on the fly bar and zero throttle.

If you were to plug the battery in first, you run the risk of having an outside signal causing the heli blades to spin and effectively whacking your hand and doing some damage (as you call it, "goes mental" ). You should always turn on the TX to broadcast a good safe signal and then plug in the bird.

I think you are asking 2 different questions.

1. Reason for the order of operations.

2. Why is there no failsafe in the event of TX signal loss.

Answer to 1 is above.

Answer to 2 is that with PCM equiptment and failsafes set, a loss of TX signal could be compinsated for, but more than likely, the failsafe settings on a heli would result in a crash anyway. That, and PCM in micro form is hard to come by.

Hope this helps.
