    Servo troubles

    My servo just started not centering but turning completely left instead. It will still turn completely right... It just doesn't center. Do I need a new servo or is the problem somewhere else?

    Stock servo?
    Whatever it is I just typed... could be wrong.

    I think it is probably the servo itself... if it is the gears you can take it apart and see teeth missing or rattling in the case somewhere. If no teeth, I would assume it is malfunctioning electronically.

    If you do not have another servo to test, you can put the ESC in slot 1 and see if you can control it with the wheel... it should still function 100% (forward, neutral, reverse)

    How would gears cause it to return to full left instead of center? Sure seems like something electronic to me but I don't know. I'll pull the servo apart and check it out, as well as try another servo. What would be the best upgrade?

    Sure enough... I opened up the servo and it smelled like fresh baked electronics. I plugged it into the receiver, powered it on, and that little motor made more lefts than Jimmie Johnson on race day! I'll have to try another servo in the morning to make sure it's not the TX or RX but I'm pretty sure it's the servo. What's a good upgrade? Also, would a gyro help me drift?

    BlueBird 390 and HiTec 5085 make good replacements. There is also an $8 one I don't remember the number or the brand...
    Gyro's can help you drift, just be sure to adjust it properly because I have read of them overworking and frying a servo.

    What do you think of using a pair of these?

    The torque rating is way lower than stock... 16.7in-oz on your Savox and 41.7 on the stock servo.
    Even doubled up, which I highly recommend against, it will not be as strong as one stock servo. The two I have given part numbers to are 60in-oz for the HiTec and 75in-oz for the BlueBird.

    I guess you're right. I just liked the speed of the savox. I think I'll get that hitec servo.

    I think Savox does make one that works... it has been so long since I researched I don't even have the notes anymore. I do remember it being over twice as much money as the HiTec though.

    Just curious... Why don't you like two servos?

    Without perfect adjustment, they will fight each other to the death.
    Perfect adjustment is not possible with stock non-adjustable linkage and even with adjustable linkage adjustments are needed every so often... usually every 3 packs or so.

    My 10th scale Summit required constant attention... most RC's that come with twin servos end up being converted to a single stronger servo.
