dads like rc too - Wow thats actually pretty good that your servos have lasted! It seems like most of the time they fail, but I guess it isn't a big deal. I never knew about the redcat free servo replacement...thats awesome!
Nitrosportsandrunner - Thanks for the suggestion on the servo! I'll look it up. One question about the servo...well...servos in general. What are those round button like black pieces and the gold colored metal pieces that come with the servo? What are they used for?
generally those are only used when mounting the servos in a airplane. The black things are rubber pushing and the gold are metal sleeves. Neither are needed to put the servo into a rc car/buggy/truck.
Redcat's warrenty covers all electronic parts for (i think) 90 days from purchase. So the ESC/radio/reciever/servo/battery/charger are all covered if they should be bad out of the box or die within that time.
I have over a year on my tornado's stock servo tho.
2 of my friends had caldera 10e's. One of them had to replace the servo, the other was fine.
Generally is the plastic gears in the servo that go. So if you slam the wheel into a wall while turning you may strip the gears in the servo. There is a servo saver, but it only does just so much.
My buddy bought a traxxas 2075 ($45 servo at hobby shop) and it lasted 3 races before he had to buy a rebuild kit and replace all the plastic gears in it.
