 I have purchased this P51-D Mustang balsa kit from Banggood a few years ago, and it arrived in a SMASHED box and some parts were damaged. There is NO plan as well as building instruction, but finally I received a hundreds of pictures  that have only a few numbering.  This smashed box was sitting in my room for long time, so I have opened the box and examined parts, and wrote parts numbers on. Some parts are not numbered, as well as not mentioned in the pictures. So guessing and guessing... Laser cutting looks good. Anyway I have started building the motor mount. Even though this simple parts are not mention in the pictures.  K3/K4 are not mentioned in this pix, and K3.K4 are angled for right thrust, but difficult to see.  Wing construction No plan, so difficult to fit ribs Wings have the mount for retracts, not for bent wire.  too big LG, and no mount parts for this LG

 It's been 9 years I wanted to build a laser cutter at home, but at that time there was no good power laser diode available. (Co2 is scary to use at home) Now we can purchase 40W (input) and 10W output laser diode.   Work area Air assist One of my friends 3D-printed a parts for air assist. https://www.youtube.com/watch?v=D5TyVozISvc I mporting DXF file from AutoCAD with correct size The DXF file exported from AutoCAD doesn't have UNIT information, so UNIT needs to be specified on setup screen.

Here is how to setup Lightburn to use SHX fonts. (refer to AutoCAD font directory) SHXフォントとは、とは中心線だけで描かれたシンプルな一本線フォントのことで、ストロークフォントやラインフォントなどとも呼ばれます。主にCADソフトなどで使われているフォントの種類です。 SHX font (aehalf.shx) TrueType font (Ariel) Power setting 【エアーアシストAF6】取り付け レンズを2.5mm隙間を空けるまで緩める Oリングを取り付け 【LightBu

 I have started building Dancing Wings Hobby Astro Jr in April 2020, now ready for final sanding and covering, since I was in hospital for two months. I have converted this electric model to glow (OS 46LA). Unfortunately the package had arrived with damages, and negotiated refund or replacement with the shop. Anyway I have started...
