What's the proper procedure to neutralize a servo? I'm installing the control rods on a Venture 60 and the instructions state I should neutralize each servo before completing the rods.

Turn on your reciever and transmitter and make sure youre sticks are centered. If you have a computer radio make sure your subtrims are at 0. Then, place the servo arm or wheel as close to centered (or perpendicular) to the surface you need to get equal distance or movement when you throw the surface each direction.

I think what they are saying is to power up the servo so it will center. Then make your arm 90degrees to the control surface. If the arm is a 1/2 spline off then use the sub trim in your TX ,if it has that feature,to get it set right. This should be done on any plane

By neutralize they mean the servos return to their neutral (just powered on) position.

They will not return to neutral unless your tx is on also then turn off the rx first then the tx to make the servo stay at neutral. Then you can mount the servo arm[wheel etc.] at the center setting and the tx-rx will operate the servo equally in both directions.

You can always take it a step further if you want and pop open the servo and makes sure the top two gears are centered as well .

But that is a bit overkill.. in most cases..

I agree with what everyone said except no one mentioned to make sure your trims are at neutral also.

That was actually mentioned earlier with the term "sub trim" in the second post.

on my radio "sub trim" and "trim" are two different animals.. both need to be centered when neutralizing the servo to center..

Also, as a side note I learned this a few months ago..at least with futaba servos, when you neutralize the servo and put the servo horn (4 arm) on the servo.. if it doesn't fit on the spline at a 90 deg angle to your control surface, just rotate the servo arm 90 deg to the next arm, and try that one.. they are 1/2 degree off per rotation or something like that.. Anyway, you may be able to avoid using "trim" or "subtrim" like this..

You are correct about the difference between "trim" and "sub trim". Also Futaba 4 arm wheels are 1 degree stepped. The arms are actually numbered to this effect. This is mentioned in the manuals that all too many of us do not read.

Manuals?? We don't need no stinking manuals!!!

Instructions are for when all else fails!!!


Just kidding of course, but we've all be guilty of skipping the instructions at one time or another.
