Servo Instructions:

This may take a few minutes to read but it could save you a few hours of frustration not to mention some $$$$

Any servo can be damaged by improper installation/use.  This is especially true for high performance servos.  High speed/torque does not mean indestructible. Many high speed/torque servos are powerful enough to strip gears, overheat, burn out, and generally destroy themselves if allowed to bind for only a few seconds, or less!

1. Choose the right servo for the job. Too weak and it will overheat from strain. Too strong and your battery will not last as long. Using a strong throttle return spring and a high performance servo to overcome it causes heat and high battery drain.
2. Do not plug the servo in backwards. On all receivers the ground (Black or Brown) wire goes to the outside of the case. Check the wiring diagram for location of the positive and signal wires.
3. Always turn on the transmitter before the vehicle!!!  Turn off the vehicle before the transmitter!!! Many receivers will pick up a stray signal causing the servo to go all the way to one side, bind, and damage itself.
4. Never plug or unplug a servo into the receiver with it turned on. The sudden arc can damage the circuits.
5. Do not use dry cell batteries. They cannot supply the amperage needed.
6. Use a speed control (electric) and receiver (both electric and nitro) with BEC's that are rated at least 3 amps. Most RTR are only 1-2 amps. Low available current will cause overheating.
7. Install a good servo saver. (Cheap insurance)  Most RTR vehicles were designed around a standard servo and have inadequate protection for upgraded servos.
8. Do not upgrade your servo unless your radio has “EPA”, “ATV”, or some way of limiting the amount the servo travels. When the linkage hits a “stop” of some kind and tries to keep going, it overheats and burns up. We do not recommend altering the steering stops or linkage to allow more travel. Upgrade your radio first!

Treat your servo like the precision instrument that it is, and it will last a long time. We do warrantee Blue Bird servos for 1 year against defect in material or workmanship. We do not warrantee damage. Yes, we have servos returned for “warrantee” with one or more wires ripped out, connector ripped off, 2 or more ears broken off the case, holes punched through the case, (can’t figure how that happened), etc., etc..  Just like your full size car. If you jump a curb, scrape a guard rail, and damage the steering (among other things), you wouldn't have it towed to your new car dealer and ask to have it repaired under warrantee!!  Same common sense applies here.
