My servo buzzes all the time when I control it. (Refer to aww dang post)

Is this servo binding?

Could be a whole lot of things. Sometimes normal, sometimes not....

Does it buzz with no linkage hooked to it and sitting at neutral?

no
it buzzes when a linkage is hooked to it. It buzzes more with an aileron.

Yes, it means there's still a load on it caused by the aileron trying to move it off servo centre.You can simulate the same thing by unhooking the aileron and pushing your finger against the servo arm. Going to have to loosen the hinges more yet.

one thing you can and SHOULD always do. Remove the linkage from the servo arm and remove the servo arm from the servo. Put the pushrod as closely as possible to where it would be if it were hooked up to the servo. Move the pushrod back and forth. If it tries to move out of the plane that you're moving it in, then there is a problem.

Also, if it is difficult to move or "sticky" then there is a problem.

The bottom line is you have to look at the pushrod from the servo's point of view.

Best fix would be to slice through the hinges and beside them, install Robart hinge pins or nylon pinned hinges, which are not expensive. The CA hinges are just to stiff. The nylon hinges, properly installed, ailerons will flop down from their own weight. Also stiff hinges will use up batt power quite quickly.

Well, CA hinges are only too stiff if they aren't installed properly.

David,
Is there a chance I could get a look at your plane? I might be able to recommend some easy fixes if I could see it.
Dennis-

What kind of servo is it?

OK guys!!

its a plain-jane Futaba s3004 BB servo.

My instruction manual says (for ailerons 3/8 of an inch of throw on high rates. The servo is moving the surface (measured with a straight ruler) when it buzzes at about 7/8 of an inch) When I tried decreasing throw (again measured with a straight ruler) it was at about 4/10 of an inch w/o buzzing.) Also will buzzing just empty the batt pack real soon?

my last major concern : Will the plane do good aerobatics with about 4/10 of an inch of aileron throw when at high rates it is supposed to be at 3/8 of an inch?? (I mean once I progress, will 4/10 of an inch be enough aerobaticism for me??)

Also while im training i can put it on teh lowest rates possible courtesy of the handy dandy D/R switch

And : DB- if my findings are kinda problematic, I could try talking my dad to take me to the field this SunDay (No chinese School!! Yay!!!)

I dunno if he will say yes though.

Yub;
If it doesn't buzz at 4/10 in. your good to go. Bat. will be OK. What I meant about the bat. is the more load you put on it the more the servo drain. The harder you push on the servo arm the more amps is drawn from the batt. When you get some xtra change, a good tool to get is an Expanded Scale Voltmeter. When your out flying , it will tell you how much power you still have left and when to recharge.

Hmm someone told me that if I solder like three resistors (are they the cylindrical things or the things with some wire on both ends?) together, it will be my very own discharger / load.
My dad is an Electrical Engineer and has like a $400 dollar digital multimeter. Apparently, it doesnt have a load.
Can you guys tell me what type of object it is? Then I can get my dad to solder them together.

I.E. is it a cylindrical thing with both wires (+ and -) on one end or the things with one wire on both ends?

Thanx for all the feedback!!!!!

PS where can I find a cheap Futaba charge plug? (the round male connector to the chage jack)
