Quick Summary
The WingTree Yuying 40g Linear is a light, smooth linear built on a POM stem in an all-nylon PA66 housing, tuned for a deeper, thockier sound. A light 40g actuation paired with a firmer 55g bottom-out on a long 24mm spring gives it a progressive force curve — easy up top, defined at the floor. For typists who want a warm, muted linear without spending up, it is a solid budget choice and the linear sibling of the Yuying tactile.
Specs and Feel
This is a clean light linear with a progressive force curve: 40g to actuate over 2.0mm of pre-travel, climbing to a firm 55g bottom-out across 3.72mm of total travel on a long 24mm single-stage TTC spring. The wide gap between actuation and bottom-out is the defining trait — the keystroke starts light and feathery but pushes back noticeably as you reach the floor, which keeps it from feeling mushy at the bottom despite the low starting weight. The POM stem in an all-nylon PA66 top and bottom housing pushes the acoustic toward deep, rounded thock rather than bright clack. Factory lube — a thin 205g0 coat on the stem legs and sliders, plus a lubed spring and leaf — keeps the downstroke smooth and quiet straight from the bag.
Tuning
These arrive well tuned, so a full teardown is rarely worth it. The 205g0 on the legs and sliders and the lubed spring and leaf already cover smoothness and spring noise. The long 24mm spring is the most likely source of any faint ping, so a touch more spring lube is the highest-value tweak. The all-nylon housing already sounds deep, so foam mods only push it further into thock; films tighten the housing marginally if you want it.
Verdict
Buy the Yuying Linear if you want a light, smooth, deep-sounding linear with a progressive force curve at a budget price — its warm nylon thock and light-to-firm stroke are easy to enjoy. It sits opposite a bright, short-travel linear like the WS Arowana Yellow; pick that instead if you want clack and high pitch. For a muted, value thock linear, the Yuying is an easy recommendation.
Frequently asked
How heavy is the WingTree Yuying 40g Linear?
It actuates at a light 40g but ramps to a firmer 55g bottom-out on a long 24mm spring. So it feels light to type on but gives a defined push as you reach the floor.
What does the all-nylon housing sound like?
PA66 nylon top and bottom housings deepen and round the sound, so the Yuying leans thocky and muted rather than bright and clacky. It is a warmer acoustic that suits foamed builds well.
Does the Yuying Linear come lubed?
Yes — the stem legs and sliders carry a thin 205g0 coat and the spring and leaf are lubed, so it runs smoothly out of the bag. Most builders can run it stock.
