hey guys, wha does the fail safe do and should i order one for my savage?
 
The fail safe puts your throttle at all stop when it senses your radio signal being lost. While some swear by them I have never needed one.
 
It will also kick in if your battery voltage drops below a certain point. I believe the Ofna and Venom are set for 4.5v.

But, if you loose your batteries completely you better hope you have a throttle return spring.
 
Speaking on the throttle return spring, I have a Futaba HS coreless BB servo on my savage throttle and the spring brings it back to idle when the power is off, but it won't with the stock servo. All the other "standard" servo I have have about the same resistance to turning that the stock servo has. My point is, if the spring can't return the servo to idle with no power, why is it on there?
 
I have the stock steering servo in place for the throttle.I took my spring off, all it did was slow the servo down and did not pull the throttle back to an idle.
 
I never had a failsafe either until one day I landed hard enough to jerk loose one of the batteries from the stock holder. The stories of what will it do when it loses the signal is true. Mine was at full tilt boogie when the battery came loose and if it weren't for a bank of dirt, it would have self-destructed itself on a building.
The next day I purchased a re-chargeable humpack and a failsafe.
I heard great things about the venom but none were available and settled on the dynamite one. I guess the failsafes are like insurance. You pay all your life and may never use it. But it's there if you do.
 
I would love to see some pics of how you guys wired your failsafe, I drilled a hole in the cover of the radio box and fed the wires through and then sealed the hole with silicone, but man is it a pain in the hat to get the wires right after charging my hump pack, it takes like 20 minutes to get the cover back on. I will post some pics of mine tommorow.
 
hey with my dad we added a charging wire out of the side so u wont have to take of the reciever head
 
I'm using the Ofna mini failsafe and fir it right inside my receiver box
