Burned Out 2 Throttle Servos....Any Ideas??
Well im a little frustrated to say the least. In the last 10 years ive never had a problem like this, so any thoughts would be appreciated. I have been running my mugen MRX for a few weeks now, about a week ago my throttle servo went out, and by went out it didnt completely stop working it just starting working extremely slow, with no load or servo horn conencted. To verify it was a servo probem and not the reciever or Batt, i hooked another servo up and it functioned fine. i bought a brand new hitec 645mg servo and installed it. I adjusted the servo, set the endpoints and ensured easy movement, then it was off to the track again. After about 45 minutes worth of driving i noticed a slow throttle response, i pulled the car back in and again the same problem. I once again checked the reciever by conencting another servo and that servo functioned fine........So im thinking one of three things.
1. the reciever is at some point fowing too much amperage or current to the servo essentially burning out the motor
2. possibly a small amount of fuel is getting in (Even though i took much procaution in fueling to make sure this didnt happen)
3. Some vibration from the car is causing internal damage to the servo.
Any other ideas or suggestions would be great, as i said they dont completely stop working they just move extremely slow (like full travel in 2 seconds). Thanks for any help
