fidracing Posted May 9, 2022 Share Posted May 9, 2022 (edited) In 2013, FID Racing made a concept off-road racer. we recorded the whole process, and posted the whole process in a Chinese forum ( https://www.rcfans.com/thread-552461-1-1.html ), and made a hit. Until now, it is still pinned in the forefront of relevant section. Though years passed, I still think it is worth sharing with more people and show how FID Racing works. In fact, on April 13, 2013, our founder and chief designer Mr. Yang started a post it on rcuniverse forum ( https://www.rcuniverse.com/forum/rc-giant-scale-cars-234/11476521-diy-1-4-cars-rcmk-600b.html ), but due to language, he didn't continue updating until the finish. I'd like to post it here so that more people could see what we make things. We didn't keep the original documents, so all the pictures are downloaded from the Chinese forum. The shame is all the videos are missing. The fabrication process spans almost 5 months. A lot of pictures. I will translate all the original words he posted in the Chinese forum, so that you won't miss anything. The post will be splitted into several updates, but this time I'll finish it. Any translation mistake, please point out. Beneath is the designer's voice. Hope you'll enjoy it. This is about the whole fabrication process of super off-road racer. It starts from upgrading 2-cylinder engine. Actually I don't know how to determine the scale. First let's do the RCMK 2-cylinder engine. Regarding its dissipation issue, please follow up my post and I'd like to hear your voice. Below is the design. I'll use RCMK 2-cylinder for it. 1st design is enforced dissipation. Sync belt drives the fan.cons: 2 cylinders have different dissipation.pros: it's mechanical. 2nd design dissipates by 4 large fans.cons: needs extra powerpros: stable and good dissipation 1/4 Super Car, Chapter Engine1: SKF bearing and Sweden seal ring for retrofiting casing new side cap and casing for pull-start, HV ignition and coil 2. mount SKF bearing (12 x 32 x 10) assembled up casing HV ignition install ignition coil mount cylinder head. fit the clutch mount last attach a picture of separate parts Chapter engine is over. Waiting for further update!Chapter aluminum alloy bodyFirst let's have a look at the design. I'll update the pictures on Mar. 22nd, 2013 (it's under Oxidation).Body Configuration Below is body aluminum parts: Update some pictures of metallic parts (before oxidation). My plan is first assembly and then surface treatment after confirmation.Let's check the chassis length (overall 850mm) Edited May 11, 2022 by fidracing 2 Quote Link to comment Share on other sites More sharing options...
fidracing Posted May 9, 2022 Author Share Posted May 9, 2022 It seems good with the engine on it. Mar. 22nd, 2013 UpdatesChapter Nylon Parts, All CNC MachinedToday I went to factory.
