Crawling/scaling can be really hard on servos. Not only are they expected to turn heavy, weighted tires on unforgiving rock, but most of the time there is no servo saver attached. Yep, direct horns are the only way most crawlers roll (versus using a saver that will give) leaving the servo unprotected to absorb the brunt of what’s thrown at it. To make matters worse, sometimes its underwater.
I don’t care what kind of servo you have, eventually this type of abuse is going to leave you with broken teeth. Don’t just throw the unit away, though! A lot of newbies don’t realize that many mid to high range servos can quickly be fixed by a trip to the dentist (aka your local hobby shop) to pick up a new set of gears.
A super popular scaling servo (and bashing) upgrade is the trusty Hitec 5646WP unit. The servo puts out around 150 oz or torque, is waterproof, has metal gears, is digital AND is relatively easy on the wallet at $54.99. I think they are the perfect upgrade for an Axial SCX10. That isn’t marketing garbage, I currently own 4 of them and use or have used them in a variety of trucks; 3 SCX10′s, Wraith, CPE Barbarian, Tamiya TXT-2 and soon to be my new Yeti.
Last weekend I finally broke some teeth during a monster truck freestyle session and figured this was the perfect time to show how easy they are to fix. Keep in mind this unit ain’t no spring chicken. It’s about 2 years old and while it used to be blue once upon a time, I painted it black a long time ago and most of it is peeling off after abuse.
