A High Performance LDS (linear drive system) for the KST X10 servo.

I would have zero qualms installing this LDS system in a dynamic soaring ship (many folks already have and with great success); anything else will be a walk in the park for this system.

The servo trays have an outboard ball bearing that helps to carry the servo shaft loads and greatly reduces servo play. The unique servo arm is designed so that it has tons of clearance, no more grinding your clevis' for maximum throw. The servo arm then connects to a strong control rod which connects to a double carbon fork epoxied inside of the control surface, this results in massive throws while the whole system is contained within the wing. Aerodynamically clean and slop free.

There are a number of ratios available. As the builder you will need to make your own decision as to which ratio to choose. The different ratios are presented like this for example: 6.35mm / 5.83mm. The first number 6.35mm is the "servo arm length" which is the distance from the center of the servo output shaft to the hole in the servo arm. The second number 5.83mm is the "control horn height" which in this case is the distance from the bottom of the horn to the connecting rod hole.

Studying the parts kit, you will find exceptionally well machined components; the CNC parts are beautiful, the anodizing is clean, resulting in a very good fit and finish. The kit is well thought out and very complete (even includes sand paper and super glue for assembly). You are given a choice for your pushrod assembly, you can use the included carbon rods to create exact length push rods or you can make adjustable length pushrods using the included threaded rod. The designer has proven that the carbon pushrod assembled using super glue can withstand 220lbs in tension. The servo frame parts are machined from 3.5mm thick carbon and the control horns are machined from 1.7mm carbon. Beefy stuff.

Another aspect of these servo frames that we liked is that they will fit into smaller servo pockets than other larger servo frames in this class. The servo pushrods are connected to the servo drive and control horn using machined pins that accept e-clips at both ends for retention. The kit includes extra e-clips in case some get lost. FYI, the designer has created an e-clip installation tool to make it much easier to install the clips. I have used it and it works very well. On the other hand removing them will require some patience.

Below is a video you can watch to learn how these kits are assembled. The kits have been improved since the video was made so you will notice some discrepancies between the video and the kit, parts-wise. The video is still relevant for learning how to assemble the system.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
