From what I have read on the forum in the past there was a few discussions on how to slow the trim speed while at higher speeds. It must be a common thing because Garmin built it into their system.

It’s described as quick but manageable with quick blips instead of holding a switch down above 60mph without it. Not required but a nice feature since you can reverse polarity if you need to and has a feature to stop a runway condition.

IMHO the trim speed reduction option is one of those nice to have items, especially for pilots new to the Kitfox, but certainly not necessary. I quickly got used to quick blips of the trim switch, rather than pushing the switch. After 10 or so hours I felt just fine with the simple stock system.
As a pilot gains experience you figure out ways to reduce your workload and be lazy. The Kitfox SS7 takes off perfectly with 1/2 flaps and the trim set at cruise trim with no flaps. So once you figure out this sweet position for trim, just set it there prior to T/O, then when your T/O climb is done and you retract flaps, you will find that the trim is already set for cruise. You hardly have to touch it except for maybe a quick blip to fine tune it. Yes, if you are doing a long climb to higher altitude you may want to reset the trim for cruise-climb then level cruise. Normally at the altitudes I usually fly at, I just hold a little stick back pressure and a little more throttle till I'm up to 1500-2000' and then just release the back pressure and throttle and wa-la I'm level cruising. Never touched the trim switch (OK maybe a quick fine tune blip). Lazy flying-works for me.
The better option to spend your money on I think is the trim position indicator. Then it is easier to preset your trim at that sweet spot I spoke of above.

How does a servo know the speed you are flying and how would a servo be able to adjust your trim? The servo is connected directly to the push/pull control rod.
Perhaps I have a lot to learn here?
First, the Garmin Auto Pilot servos are connected to your Garmin G3X, (in my case). The G3X receives all the Pitot Data, so the computer knows your airspeed. It is the Auto Pilot servo (receiving info from the G3X) that is connected to the push pull tube of the elevator. As for the Trim Servo, It is in fact connected to the bottom of the horizontal Stabilizer, raising and lowering the leading edge of that wing. That trim switch is wired into the Garmin system so that the Garmin can adjust trim to lighten the load on the AP servos. All this, I am sure, applies to any of the Glass Panels. That function works with or without an Auto Pilot if I am not mistaken.

Okay, good to know
Thanks
