1) Go back to the stock Losi throttle linkage and all accessories.
2) Get a high quality servo if you are using inferior servos. ( JR 9001S or Futaba 9351)
3) Make sure to not let the spring on the linkage comletely bottom out.
4) Cut as much excess linkage off behind the outside collet, so the linkage does not hit the body.
5) Set your epa's so you do not have too much throw on the throttle side or brake side. You can pull the brakes too hard along with bottoming the spring out. Only use as much brake as you need to slow the car in a controlled manor.

i also noticed the servo felt quite hot, and the engine was only idling, and it was getting at a fairly high temp too, so would the heat from engine get to the servo? its like right next to it, or through the chassis, the servo last around 15 - 20mins of use (racing) before this happened, i was only running in a motor

and the servo was a Hitec 625MG

the receiver felt warm too, but the steering was fine
Battery - 1200 venom 6v hump pack
DX3.0 - pro receiver

so its my linkage?

I'm loving this thread.
I have been running a Hobbico CS-64 servo for throttle for a year and a half with no isssues in my 8ight 1.0. To say this servo is cheap is an understatement. $21 or so. My linkage is set up properly. I run no throttle return spring, and the rear of my radio tray is quite loose.

You are completly right. I hate those servos and will never touch one again. Buy the Losi Throttle Linkage. Set it up correctly and you will never have a problem again. Here is the part from A Main:http://www.amainhobbies.com/product_...ducts_id/30452

I would kind of blame it on the linkage also. Use the right linkage and set up the throttle right and you will never have a problem.

I dont know if I would consider hitec "inferior" . I know several losi guys in my region that switched to hitec servos for there trucks and buggies because that was the only thing that would stay alive for them. I see drivers beat the snot out of there vehicles all the time that have hitec servos and the servo still survives.

Hitec's are anything but inferior! I would say Hitec and JR servo's are the two best out there..at any price..I bought my first non RTR servo 6 years ago, and it was a Hitec and it just crapped out 3 months ago! $45 for 6 years of service....Give me Hitec everytime!

I am a pretty loyal Futaba user myself but after countless times of seeing a hitec srevo just being pounded on and still holding up I am giving a set of 7955's a try.

A good servo for low price is the hitec hs-985, I highly recommend the king headz servo stiffner brace, it made a huge difference, as soon as i bolted it in i could see a difference..

the 2.0 tray is a MUCH better option then trying to stiffen up the 1.0 tray....you will have to modify the dirt guard and possible the chassis to use it tho.
