Info:

  • Important, YS engines are designed to run a minimum of 20% nitro but Probuild & YS highly recommend 30% nitro for best operation unless otherwise stipulated in the YS Manual. Both YS & Probuild recommend Model Technics Bekra 30% mix.
  • It is extremely important to get the correct gear ratio in your helicopter because incorrect gear ratio can damage your engine.
  • On the last flight of the day a fuel line clamp should be used to stop the engine in order to prevent rust & corrosion.
  • The Hatori 2123 Is The ONLY Pipe Recommended & Designed By YS For The YS120SR

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
