e-Miniature Aircraft Furion - Razor - Ion-X > Hacker controller question...

I'm running the stock Hacker 77-0 controller in my Ion and had a 'hot stop' today. I landed, put the heli on the bench, shut the transmitter off, and the dang heli started to spool up -- ripped my finger pretty good as I was still holding on to the head. Don't like that feature! Is there a way to have it stay off when it no longer has a signal from the transmitter?

Hi!

First, I would like to say that I think it is a bad idea to turn off the transmitter when the receiver is still on. Especially if the motor/controller are still connected to the batteries!

That being said, I had this happen to me once when I hit the power switch on my radio while clipping in the neck strap. Sure enough the motor started up! Fortunatly I was standing back from the heli and I got controll back quickly once I turned the radio on again.

Turns out I had the PCM failsafe set wrong. It was going to 100% throttle rather than 0%. Oops.

Do you use a PCM receiver? What is your failsafe set to?

Regards,
Nick

Thanks for the reply, Nick. I agree about never shutting the transmitter off first...however, I do have senior moments. That said, yes, I also did not have the failsafe set for idle. It is now!

Also, on electrics, in addition to fail safe set to zero, I set my throttle hold to zero throttle as well. Typically, after I land my electric helis, I would put it on throttle hold before I walk up to it to disconnect the battery. This way, incase I bump my throttle stick by accident, it won't spool up and cut off my hands.

Bill,

Do you have any idea what might have caused the "hot-stop"??? Real curious to hear what you find out.

I have 250+ flights on my IONs and nothing like this has happened (well, one did catch on fire on very first flight, but Hacker said it was defective). My ESCs barely get above 100 degree F.

Are you close enough to the Hacker guys to take it to them to check it out??

The failsafe and throttle hold recommendations are necessities for these electrics. Anything weird happens and you want that motor off!

The 'hot-stop' was caused by a senior moment, Jon. I had my failsafe set for a 25% throttle setting - causing it to spool back up when I shut the transmitter off!

OOOOOOOOOOOOHHHHHHHHHH!!!

I thought it had a problem in flight, then you put it on the bench and had the fail-safe/transmitter off problem.
