| servo saver
Is it necessary to use a servo saver for crawling. If so, what brand or style do you prefer?

I wouldn't and haven't for about 1.5 years of bashing and crawling. I just run a heavy duty servo with metal gears and metal arm. |

No servo saver, that's what titanium gears are for.

The original plastic flexible link rod was the servo saver... But most find that to be a fail out the box. I don't run a servo saver either. But a stronger servo will be critical to handling the abuses. Even at crawling speeds... and with a solid link rod for the steering I broke 4 plastic steering knuckles and two Chubs. I never ran into any obstructions... they just let go. Sooo... if going with a solid link rod and no servo saver to protect the steering components... It would be my advice to upgrade the Chubs/Knuckles to alloy units. Even with a stronger servo and alloy Chubs/Knuckles... you may still break things if you hammer into immoveable objects. If you crawl at speeds akin to a crawler and avoid impacts... you will be happier |

| Re: servo saver Quote:
Steering the wheels on a slow speed crawler takes a lot more torque than steering the wheels on a fast moving SCT truck. You can validate this by trying to steer your 1:1 rig at 1 MPH and then at 55MPH. Servo savers are designed for high speed / low torque applications where you want to protect the servo from sudden high speed impacts of short duration. The spring inside the servo saver compresses when hit with a impact and then releases preventing damage to the servo. Under low speed / high torque conditions such as crawling, the spring will fully compressed most of the time offering no protection to the servo. The solution is to use a good quality high torque servo and forget using a servo saver on a crawler. | |

Personally I would NOT use a servo saver. They are terrible on crawlers because of the high torque servos they just won't work well. Just get yourself a Hitec HS-7980TH with 611 oz of torque and be done with it. Don't even think about a worthless servo saver, if you were into short course then that's where the servo saver comes in handy..

I don't run a servo saver on my SCT either.

Servo savers are only needed to protect weak servos. Real servos don't need savers. Plus all the generic servo mounted savers are far to soft to provide precise steering effort. |

Don't get a servo saver. You won't be driving fast enough to need to protect the servo from a sudden sharp impact. All you need is a high-torque metal-gear servo and a metal servo horn that clamps onto the splines for added strength. They're really only useful nowadays on high-speed vehicles with exposed wheels, like monster trucks, stadium trucks, buggies, and truggies. |
