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.

      Seems like a decent product, but it's not for me
      First off, a small caveat: this is the first manual grinder I have used. I am trying to highlight things I think might be unique to this model, but some of these might be "that's just how manual grinders work" problems. First and foremost, I can only cram about 20g of coffee into here at one time. If I'm making an 8oz cup, that tends to be enough -- but no larger than that. I also find it hard to load; last time I tried to just pour beans in most of them ended up on the floor. One scoop at a time is annoying if you are adding 20 grams of coffee, especially if you use a small scoop. Also, I personally dislike that the body that holds the unground beans is opaque. I have to turn the thing upside down to determine if I have more left in there to grind or not. This is likely the same for other models but I don't think it makes for an ideal user experience. Now, on the upside, it's compact, easy to use, and easy to clean. I don't know how to gauge the accuracy or consistency of the grind, but it seems to produce a somewhat finer grind than my electric burr grinder at what I would expect to be the same setting (20/40 on here is more fine than 14/28 on the other grinder, even though I would expect both of those to be "medium"). I'm someone who prefers slightly coarser grind, even for pour over, so this is another strike against it in my book. I have only used it two or three times due to usually making larger cups that this can accommodate, and also not enjoying spending 5 minutes rotating my arms to get the coffee ground. So I also cannot speak to durability, but the plastic and glass both seem sturdy so I do expect it to last. All in all, I love that it is lightweight, portable, and easy to clean, but I think I'm someone who prefers the ease of use that an electronic grinder can provide. And seriously, IDK how anyone is getting more than 20g of coffee into this thing at one time.

      Perfect for Lattes

      Good for steaming 8-10 oz of milk. The nifty tool is good for scooping out your puck.

      Almost blew up my microwave
      Size: 20 Ounces, Size: 20 Ounces
      TL;DR "A hilarious microwave mistake turned into a great home cafe upgrade. This 20oz cup is straightforward to handle, looks incredibly professional, and holds a level of heat that will literally burn you if you aren't careful." . Bought this for homemade coffee brewing, just to spice things up. But as I go ahead to heat up my new shiny stainless steel milk frother cup in the microwave, whoopdy doo. Ya can’t put stainless in the microwave! Regardless, it’s still a straightforward frother cup to handle, making it a great dollar investment for upgrading my home cafe setup. . 1. Spotless Stainless Steel: Its sleek appearance made me feel professional in the hands of an amateur like moi. Great quality! 2. Temperature Retention: I accidentally burnt myself because it stayed so hot, but that is a major positive. Proving the insulation works perfectly and keeps the milk piping hot. 3. Size: The 20oz capacity is accurate, providing the perfect amount of space for frothing without any overflow.

      Decent pitcher

      Smaller than expected. I frothed 5 oz of milk and it was almost a mess.
