Runaway with spektrum?

[squirrel]

My return spring is strong enough to pull the servo to neutral albeit slowly. I may have to throw a second spring on there to be safe.

All points are well taken, but still no explanation as to why my rx went to full throttle on signal loss instead of the full brake setup I had bound it at. I initially thought it was low voltage, because I had been running all day on that battery, but when I got home it still had plenty of charge left. I even duplicated it several times with a fresh battery before I re-bound the system.

So the question remains....Why did this happen and what can be done to prevent it from happening again?

Had the same problem over the weekend breaking in a motor for Awful Kanawful. Had the truck idling and he turned off his radio(his goofy azz idea! lol) Truck went WOT for a second till he turned the radio back on. His was because he set up the failsafe and then had to reverse the servos and never fixed it.
