It's good to use a receiver pack, hump (3x2 configure, 5 cell) or straight pack like the Orion's Marathon 1600mAh, they'll give you more punch and last much longer...
A fail safe is not a must, but it'll save your truck when the worst happen i.e. lost of signal, interference, that'll send your truck to meet it's doom at full speed, especially you're using an AM radio...
Lastly, make sure the 4AA batteries you're using now for your receiver is not those rechargeable type, as rechargeable batteries will only peak (full charge) at 1.2V, so 4 x 1.2V is only 4.8V... You'll be 'out of juice' in minutes, and might cause your truck to 'run-away'...

yea its the stock tq3. i will get the 2.4ghz. eventually. im using energizer batteries, not rechargeables. even after i get the traxxas link 2.4 and the 5 cell hump pack,should i continue to use the failsafe? ok, i found a guy selling a new failsafe for $5 shipped. heres a pic of it-
When you change your radio, if it already has the fail safe function, you will not need to use this 'plug-in' fail safe anymore; just set it from your radio, and normally for radio with a fail safe function, you'll even have the 'low-batt fail safe' (when your receiver pack voltage drops to 4.8, and your radio voltage drops to 9.8/5.0 depend on your radio required voltage/cell).

This fail safe should be good to use for now.

The Traxxas Link 2.4Ghz radio is equipped with a failsafe -quote from the Traxxas Slash Ultimate Manual, p31 (uses Trx Link 2.4 radio)-
"Failsafe -
Your Traxxas radio system is equipped with a built-in failsafe
function that returns the throttle to its last saved neutral position in
the event of a signal loss. The LED on the transmitter and the receiver
will rapidly flash red."
So as soon as you get your Trx link radio, you can do away with the failsafe.
roychan69 - rechargeable AAs nominal voltage is 1.2v, fully charged voltage mine are 1.42-1.48v, they come down pretty quickly, so you wouldn't use 4 of them for an rcvr pac (you'd use 5). I've built many rcvrs packs using 5 AA cells. The new LSDs (low self discharge) work really well since they don't have the self discharge that ordinary rechargeables do.

i have the dx3s... it can only show the rx voltage but only with telemetry...
does the m11x or 4pk/s have the sames feature with out telemetry? i'm planning of getting either of the two...

There are needs for 2 type of failsafes, one for loss of signal and one for low voltage rcvr batteries. The link radio has one for loss of signal (interference) but not for low battery (or no battery in case they were to get tossed out or become disconnected). Usually, a high capacity rcvr pac made this a non-ssue.
I don't know about the 4PK, but my 3PK has both a loss of signal type failsafe and a low batt failsafe. I had to set both up. I would be very surprised if the 4PK, 4PKS did not have the same features.

BUT, if a receiver battery is unplugged/wire cut during running, the truck WILL STILL RUN-AWAY... A fail-safe WILL NOT WORK when no battery is connected...
