I purchased a T3 for my son's birthday last month and he's run it consistantly on the street in front of our house, with no problems. 2 weeks ago, I took him and his friend to a local RC dirt track to race each other. They're still learning, so they ran into almost everything on the track. Half way into his second battery, he stripped the servo gears and was done for the day. I took it to a LHS and the guy told me it was common on these and sold me a second set and re-adjusted the servo-saver. Last we he stripped out the second set. Do I repace them again, buy a new servo with metal gears (I really don't want to), or what? Please help!! Thanks :confused:

Well, several things ...
Most importantly, that servo saver is kinda finicky. The shop guy probably did you right, but there is nothing like understanding how it works and kinda like doing it yourself, if you know what I mean.
To really adjust it, it must be fully disasembled and cleaned. Dirt gets in there and starts eating up the plastic. It may even be worth it to replace the steering assembly, and then rebuild it, noting the instructions carefully.
Yes, metal gear servos are tougher, but plastic gears should last a long time assuming the servo saver is functioning correctly.
I am not sure what servo comes in the RTR T3, but it is probably a very low end unit. This could be making your problem worse. Servos can get quite expensive. If you decide to replace it, some good products are made by Hitec and Cirrus that are cheaper than the big name brands, but are usually just as good, especialy for your needs.
Be certain of the servo saver's operation, then get a new servo if that does not work out.

Good advice Jeep, The other thing that may work is to add another servo saver directly on the servo. It replaces the stock servo horn. "Kimbrough" makes a small one that I think will fit, but you'll have to check to be shure. It might be too tight in there. The cost about $4. I ran a heavy one on my GT for years along with the stock setup.
Hope this helps.

if you decide to purchase a metal gear servo i have experience with the cirrus cs-60bbmg servo from hobby people and it is tough as nails. i would show pics of the damage i did to my truck but i would be sued for abuse. however the servo lasted its 22 bux and isnt very fast but it werx okay

Just put a little grease in the servo saver. I was stripping a servo every time I ran my truck but after putting grease in the servo saver I have never stripped one again. :)

I had the same problem on mine, and jeep, it has a Hitec HS-303, and i stripped it out on my first day at the truck, although i did have an extra servo, and it is an excelent one, a Hitec 645 MG, and it runs ya bout 50, and i have hit some things, that would smash my other servos, but this one is excelent!

Wow, same thing. Stripped mine after 2 weeks, noticed that I couldn't even move the servo saver, loosened it up, added the grease and haven't had a problem since. I also went ahead and bought 2 extra sets of gears (whopping $4). I also heard @ my LHS that on the HS-303 you can upgrade the gears to metal. Is that right? Wonder if it is really worth it or better to just get a faster/stronger servo.

simply cleaning the stock servo won't typically keep a plastic gear servo alive in a T-3... like mentioned above, a small bit of black grease needs to be used on the mating surfaces, And the bottem of the "V" can be rounded off to more of a "U" shape.... plastic gear servo's will live longer this way, but they still won't last forever..
if you don't want ANY problems, pop the bucks for a metal gear servo.... (but you will still need to coat the stock saver with black grease)
peace out... :)

I use a hobbico metal geared servo in my TC3. I stripped out several regular servos before that one. I haven't had a problem with it since. I think it was a CJ5 (or C something 5) It cost around 25-30 bucks. Good servo.
