I've been using a Sanwa ERG-RZ for throttle for the last 3 years, and while it may not be "top of the line" anymore, it hasn't let me down yet...But it does have a lot of resistance even when powered off.

um. No sir. I have been using 3 return bands on my 7985 servo and no problems. My switch/battery took a dump and it closed it fine. Been doing that for 18 months. No problems what so ever.

It doesn't take long for the FASST receivers to overheat and shut down. My friend had this happen to his D8T this weekend. When we got it back to the bench, I looked at the RX and the power LED went from green to red. After a few mins if cool down time, everything worked fine. Try using the heat reflective tape on the OUTSIDE of the radio box on your (next) buggy.

Another trick I use in my GT 2 is to ream a 3/4in hole in the bottom of the truck's radio box. Next, I use two layers of servo tape to mount the receiver. Here's the real trick, only place 1/4in wide strips on each end of the bottom of the receiver, leaving the center exposed. This allows enough air flow to keep the receiver temps down.

I'll post some pics later tomorrow of what I did. Gonna do the same thing in my friend's 1/8 scale as well.

Sounds like the throddle servo took a dump.
I've seen a few servos do the same thing before.
One minute it's working fine the next minute it
slams to the full throddle position and locks.
The RTR Ofna servos are known to do this.
Remove the servo and smash that P.O.S. with a hammer.

it was a ofna servo .. i had a futaba for steering .. and since the servo smashed my car with a hammer i should return the favor ... Its so weird .. but i learned something ... i have a Nova Engine i can use .. maybe pick up a D8 or a RC8 (easy pay on Tower) .. Im just nervous to use this receiver and and radio again..

Or i can get a picco or Jammin X1X .. for 300 - 350 but they seem old and i would need to replace the servos so that adds at least 100.. so not sure that is the best i can do... and the picco is the one i just destroyed

+1.

I had 3 FASST receivers do this to me. They do not like the heat inside a nitro receiver box. FASST receivers and nitro buggys don't mix. My M11 works excellent though.

I ran across what I thought was a great deal on an almost
new RTR Picco buggy ,minus the engine. I fugured
I would use it to break-in engines and it would save
some wear and tear on my race gear in the process.
Not two minutes after firing up a sweet GRP Tuned .28,
the RTR servo took a dump and away it went. I ran a
long way to get to it, but it was to late for the engine
to be saved. The buggy landed upside down with the
engine screaming wide open. That engine cost me
over twice what I paid for the buggy. I still kick myself
in the arse for ever trusting that damned RTR servo.

Its not the radio's fault you didn't set the failsafe.. I've had my 3pm-x since they came out and have never had an issue with heat, not saying it deosn't happen. Had it in a revo last year and now in a D8t this year.

I had the same problem with my old 3pm. The failsafe didn't always kick in. I did some testing on it with a blow dryer. When it overheated, the failsafe only kicked in about 50% of the time. Been using a M8 for the last year with no problems

+1 except I went to the M11X after fighting thermal shutdown. I did however have my failsafe set so I wouldn't have a run away.
