A High Performance LDS (linear drive system) for the KST X08 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.

      Nice looking pair of shorts
      Size: X-Large, Color: Dark Grey, Size: X-Large, Color: Dark Grey
      I ordered these to have as a casual option for the warm weather. These are made of 95% polyester, but feel soft and comfortable. They are of good quality and seem very durable. The material is fairly thick, but still lightweight. I love that the pockets have zippers to keep my items secured. I did not find any loose threads or visible defects. Good value for the money.

      Not terrible, but the material and fit just weren’t for me...
      Size: X-Large, Color: Khaki
      I really wanted to like these shorts. From the pictures, they looked precisely the style of summer shorts that I like. Unfortunately, I was left somewhat disappointed as soon as I opened the shipping package. The biggest thing for me is the material. These shorts are much shinier in person than I expected from the listing photos. Depending on the lighting, they have a kind of satin sheen to them, which is not really the look I was going for and not what the photos depicted. I was hoping for something a little more understated; closer to khaki material. The fabric also holds wrinkles more than I expected. Even after smoothing them out or folding them carefully, they seem to keep creases pretty easily. It gives them a slightly messy look unless you’re constantly adjusting or hanging them properly. The material is also very thin, which would be nice, but likely is the reason the wrinkles are so apparent. Fit-wise, they land in that awkward middle ground where they are not exactly uncomfortable, but they never quite feel natural either. The cut just sits a little strangely on me. It is hard to pinpoint exactly why, but they don’t drape or move the way my favorite shorts do. Sometimes that happens where the proportions technically fit, but the overall shape still feels off. That said, they are not all bad. The construction itself seems decent, and they feel like they would hold up reasonably well to regular wear. I also appreciate that they are lightweight and breathable enough for warmer weather. At the end of the day, these might work really well for someone who likes a shinier look and does not mind a more structured fit. For me personally, though, the combination of the sheen, wrinkle-prone material, and slightly awkward fit kept them from becoming a pair I would want to have in my regular rotation.

      Comfortable Everyday Shorts with a Clean Casual Look
      Size: Large, Color: Dark Grey
      These shorts strike a good balance between casual comfort and a more put-together appearance. The twill fabric feels durable enough for regular wear while still being lightweight. The drawstring adds flexibility in fit, which makes them easy to wear in different settings—from casual outings to light activity. The 7-inch inseam gives a modern, slightly athletic look without being too short. Pros • Comfortable fit • Versatile casual style • Lightweight but durable fabric Cons • Not performance-focused • Limited stretch compared to athletic shorts Overall A solid everyday short that works across multiple casual settings.

      Good Basic Pair of Basic Shorts
      Size: Large, Color: Khaki
      These are a good basic pair of shorts. They fit well with a comfortable drawstring waist and a nice length that’s not too short or long. The material feels a bit thin, which is actually a positive for summer since they’re lightweight and breathable. The color came out a little more gold than true khaki in person, but it still looks decent. Overall, they’re solid for casual wear, beach days, or just around the house. We’ll see how they hold up after washing, but so far I’m happy with them for the price and will be wearing them regularly.
