I purchased servo to upgrade from stock ones. I have two, but only see wires coming out under the throttle and break servo. Also it's a lot smaller than stock servo, was I suppose to order something else to make it fit?
 
Ok got the steering done. But that 645 looks smaller then the stock servo. Also I'm only replacing the one under the steering servo correct?
 
The 645 is for the top servo. The one that hooks to the carb and brakes.

The steering servos are on the bottom laying on their sides.
 
Ok had to check the servos, now I see what your talking about. So for the steering do I replace one or both?
 
If you plan on running 2 servos, they need to be matched. You would replace both. The 5765 is the best fitting servo. The larger servos won't fit as nice under the battery box.

A lot of guys will run a single steering servo and just omit the one under the battery box. It is easier to set up a single servo than the dual setup.
 
Ok so remove the arm here on the left? Should I remove old servo also?

Sorry you gave the answer to previous question. Do you have a video on how to setup properly once installed.
 
Not off the top of my head.

Get it mounted.

Power it up and let it center.

Install the horn.

Install the and adjust the linkage so that wheels are straight.

Fine tune trim with transmitter.

Set the end point adjustments on the transmitter.

That's about it easy peasy...
