Did you set your end points ? Is there any binding with the linkage ?

If your killing servos that fast, it almost has to be a setup issue.

yup I agree with the top post, there has to be something wrong with your setup it would seem. What seems to be going on the servo's, something electrical or physical like the gears. Also what servos are you using. If they are really cheap they may not be able to handle what you are putting them through.

Deos the T servo come back to life later on?

Have seen many increase EPA on the brakes to help stop the car as the brakes age. The servo can only pull so hard before it burns up. If your brakes are too worn or slick the servo has to pull too hard to stop the car.

Also make sure your rubber mounted and not screwed down too tight, and shim the servo so its about 3mm off the chassis. Don't let it get too close to the chassis.

If your running a Losi, upgrade to a carbon fibre radio tray.

Are those servos analog ?

Analog servos don't mix with latest receivers ( hrs, gigahertz ).

Use digital servos for latest receivers ( hopefully from same brand for less headache ).

Sounds like a epa and binding issue.What tx are you using and servo's? A 3PK will run analog servo's as long as it's not in HRS mode.

There is nothing wrong with running analog servos with newer receivers.
Just as DezSlash said as long as you don't run them in a "High Response" mode.

I run a 4yr old Airtronics analog 94359Z with my Futaba 4pk with no problems.
