Futaba failsafe

Would appreciate comments from Futaba users.
Checking failsafe on a fellow members model, we discovered that if the throttle stick was off the low position, the failsafe was disabled. The motor still ran and throttled, but did not shut down. The second try, with stick on the stop, it worked.
This seems to me to be a potential problem, but I am not conversant with the current Futaba radios, so did I miss something?

That's how the 'kill' switch works Stuart I suspect in order to avoid accidental kill operation - 'failsafe' however is based on losing signal at the Rx and will take the throttle down to the pre-set value (every time).

It didn't, that is why I raised the query. When it was switched on with stick not at min, switching tx off did not operate t he failsafe.

Stuart

That doesn't sound like its been set properly Stuart. I test my failsafe on all my models at the start of every flying session and they have never failed to operate (i.e. I open the throttle full and then switch off the tx and watch/listen for the throttle to close. Please can you advise Tx and Rx models (and are we talking Futaba or Orange or similar Rx?).
I will take a look if you still have concerns! Ps there is a mode which is 'hold' rather than failsafe - could this have been deployed?

Stuart

Is it possible the failsafe is set to 'hold' not throttle to idle, so when you switch off the tx, the throttle is holding it's last position?

Beat me to it Jon - I just amended my previous post!

Cannot answer how it was set, just how the check went. But, to me, it still means it can happen which concerns me.
Maybe we could look at this next time we meet at the field.

Stuart

We must have posted simultaneously, great minds and all that

John - The problem was with Jason's Futaba radio which I assume you know well.
I'm now Futaba with a FrSky module so have little knowledge of current tx's
