I assume by "neutral" you mean some preset intermediate value. But that's not how my DX4C operates with the SR410 and SR2000. Most times the servo will simply not receive any signal. Sometimes it receives a signal that drives it against its stops. The first situation is a bother; the second situation will burn out a servo if I don't notice in time. I've already lost an A5040 that way.
Copied from the DX3C manual:
"Failsafe positions are also set during binding. In the unlikely event that the radio link is lost during use, the receiver will drive the servos to their pre-programmed failsafe positions (normally full brakes and straight steering). If the receiver is turned on prior to turning on the transmitter, the receiver will enter the failsafe mode, driving the servos to their preset failsafe positions. When the transmitter is turned on, normal control is resumed. Failsafe servo positions are set during binding."
The last sentence implies that failsafe positions for both channels depend on what comes from the transmitter, and that was the case for my DX3C when using the SR300.

Airplanes, helicopters, boats, and cars are all vehicles. But I'll assume by "vehicle" you mean "car". Exactly which specification for the A5040 am I exceeding by using it in my 1/12 scale car?
Okay, let's explore this a little further:
What is the acceptable pulse width and frame rate for the A5040, or any other "air" servo?
What is the acceptable pulse width and frame rate for a Spektrum "car" servo?
What is the output pulse width and frame rate of a failsafe signal from a Spektrum "air" radio?
What is the output pulse width and frame rate of a failsafe signal from a Spektrum "car" radio?
It doesn't require imagination. It only requires that you use input from your customers to improve your products.
Is there a reason the DX4C/SRS410 combo provides a failsafe signal only for the throttle, but provides absolutely no failsafe signal to the steering (which is correctly stated in the manual)? And will the DX6R fix this problem?

I have always used "A" servos on ground vehicles vs "S" for 2 reasons. 1: The cord is longer on A vs S, and I need this for my Slash specifically, and 2: I can "feel" the difference in the servos. I dont use failsafe, I personally dont need it.

A servos are for AIR applications and the dead band is very wrong for surface applications and typically results in much more premature failure of a servo. As long as you are OK with this, then its all good.

How many instances does your car go into failsafe mode? If you set your car up right, It should never go into failsafe I.E. The trans battery is low or using some goofy ass setup on your 12th scale.
If it does go into failsafe what would likely be the reason it did? Operator error Teddy Brosevelt....
And if it does go into failsafe the car goes straight or turns left what difference does it make. You Will crash. If the expectation is, or as was said "imagine", that the car is gonna just stop. That's not happening. There isn't any reason the engineers have to address your concern . Ultimately it is you that sets the car up to NOT fail

I am a Spektrum customer. Failsafe is important to me. If I am the only one that values it, fine. I'm not asking about it for your benefit, I'm asking about it for my benefit.
Hacker07 has asked me to send my questions via email, and I have done so.

Guys this does not have to be a heated and attacking.
Ryan does care deeply about making customers happy. His involvement on this forum is a sign of that. He reads this stuff and wants it to be right. He is listening and gave out his work e-mail because he cares. He will work see what he can do to address this issue. Does not need to be done on the forum for what seems to be an issue with an individual. Again he is listening and working to incoroporate feedback and requests. Again with this new radio updates and adding features will and new software upgrades will be easier than ever. This radio is going to amazing and create amazing value to the end users.

Is it possible to make selfie with this radio and post it to Instagram?
