Low cost servos for homebuilts, LSAs and microlights such as the TruTrak or Dynon do not have this feature. That means when you move the controls you are back driving the whole mechanism: lever, arm, internal gearing and electric motor. I have experience with the TruTrak and I do not think the Dynon is different. When you move the lever by hand, it seems quite stiff. Once the servo is installed in the aircraft, you can feel the very slight additional friction when moving the control stick, but don't worry, as soon as you are in flight, you do not feel the servos at all and you can enjoy hand flying as before.

In your opinion what would be the lightest finish?

You are correct that the Dynon servo does have some small residual torque when it is not energised. I am absolutely not an electrical expert but I think it may be that the servo has a stepper motor and the stiction is felt when the rotor moves from one pole tooth to the next. In any event I have found that although I do notice it on the ground, it has no effect on the feel or responsiveness when in the air. Of course, when the autopilot is engaged, the servo drives the controls and any stick input will be counteracted by the servo which will disconnect with heavy input. By the way, my system uses the Dynon D10A only. The AP74 auxiliary autopilot panel is a 'nice to have' item but absolutely not necessary. Cheers, John ------------------------------------------------------------------------ ORIGINAL MESSAGE From: Martin Tuck Subject: Europa-List: Dynon Servos I was watching a Dynon video on installing servo stops and noticed that the servos seem very stiff. If two are in the (pitch and roll) system doesn't that stiffen up the nice light control responses I am used to? Maybe once power is supplied they loosen up? I would have thought adding power to them is the way to have them 'lock' for autopilot operation. Clearly I don't know how they work. Can someone using Dynon servos offer their experience? Thanks, Martin Tuck Europa N152MT ________________________________ Message 5 _____________________________________ Time: 11:10:22 AM PST US Subject: Re: Europa-List: Interior finishing From: Paul McAllister The only thing I can add on Zolotone is to prepare your surface well and then spray it with clear coat to protect it. I did put some upholstery in my airplane in areas of high wear, for example the baggage compartment.
