Servo torque question
My wing flaps (three separate sections) on my Byron AT6 are controlled by a single Futaba S3302 servo. The center section of the flaps is the one that is connected to the servo and this section retracts to a nice tight configuration to the fuse. An outer section droops down about a 1/4" when retracted. I am able to bring all sections up tight via the tx adjustments, but then the servo buzzes.
Question: 1. Would a higher torque rated servo be able to answer the additional force without buzzing? 2. If so, what size would be recommended?The Futaba S3302 is an 89 oz/inch servo. |
RE: Servo torque question
I am not familiar with your airplane, but, it seems to me if the center section is up good and is mechanically connected to the other 2 sections of flap.....then you need to adjust the outboard section of flap mechanically.....The servo buzzed because you were up against the flap stop and were over driving the servo.....a servo giving more torque mifgt damage the center section of your flaps

RE: Servo torque question
The center stop position of my center flap section will allow this section to actually tuck in a little tighter when I adjust (over drive the servo). When this is the case, the outboard flap section will follow up tighter to an acceptable position, but then I am overdriving the servo. There isn't a convenient way of adjusting the outboard flap and maintaining uniform alignment when the flaps are deployed. This is why I wondered whether a higher torqued servo would be able to retract to the required (higher/tighter) position without over driving it. Hope this is a clear description. Thanks.

RE: Servo torque question
Thank you Gentlemen. From your input, I realized that the servo arm in the retract position was binding in its slot against the fiberglass fuse. I just relieved this slot and now we are "tucked up" to a satisfactory position. Thanks for your input.http://www.rcuniverse.com/forum/js/f...eeth_smile.gif

RE: Servo torque question
Jetmech & Airbusdriver are absolutely correct if your servo is is stalled at the up position then trying to force it up even more for the outers is no solution.
You must fix the problem mechanically convenient or not if having the outers hang down is unacceptable. Change or modify the linkage or better yet just secure the flaps in the up position permanently. John |

Ah ha, just saw your last post as I was typing and happy you corrected it.
