losi baja rey悬挂整形大改
【写在前面】经历之前几次发帖经验，这次文章就提供一些改造思路和解决方案。具体解决方案可作为参考。老规矩先分析车架存在问题：
①前摆臂下摆离地间隙底；
②避震架高度不够导致避震器长度受限；
③原厂舵机力度小，原地转向吃力；
④原厂电设参数调整难度大，不直观；
⑤整车质心靠前，飞坡容易载头；
先上图

问题③④属于很好解决的问题，直接更换舵机和遥控器就行。
问题⑤可以通过给整车配重的方式即可实现调整重心，这里我是在后油箱和原先放接收器的地方一共放了三块铁锭。（配重后要记得加固防滚架我直接用拉杆来给防滚架打孔加固连接。）

解决问题①②需要动前悬挂的结构，这里原本有两套方案，但是在考虑到之前论坛很火的主销下沉C座后，发现其转向时不能很好的运作，所以还是选择了一个成本较高，但是悬挂和机械结构稳定的方案二，（这里直接上图对比方案一和二）

确定方案后就是摆臂结构设计和材料选择的两个方面
设计上：这里用solidworks绘制摆臂结构，参数参考原厂摆臂尺寸，避震受力点也是。原因即为原厂的参数调教是很综合，且很耐用的选择。同时通过有限元分析辅助力学结构设计，这里涉及到很多专业相关，不展开叙述
材料工艺上：由于是定制零件，且用于体量不大的模型上，在权衡成本和工艺后，最终材料用尼龙，工艺用MJF的多射流熔层贴3d打印技术。强度和成型件韧性都优于注塑件。（这里放几张成型件图和有限元分析截屏）

此次悬挂的改动目的是为了在具有车辆操控和耐用度的情况下，最大限度提升悬挂行程
最终参数：前悬挂行程120mm，前防倾杆为rock rey的hr版本，后悬挂125mm，后避震筒120mm。
C座和转向杯与之前一样，用rock rey的原厂件，与losi家同系列

【写在最后】losi baja rey算是和我度过了相当长的备考时间，期间修修改改两年多没有下地，至今才整备完成。此贴的发布过程也算经历颇丰。
希望此贴不用沉的太快 发几张图片，一起回顾一下，多讨论讨论，不然该沉帖了

还是那个问题…纯后驱…加大了主销后倾么？
主销后倾是原厂参数，就是rock的C座参数 好车好帖，楼主费心了https://app.rcfans.com/public/emotion/face_001.pnghttps://app.rcfans.com/public/emotion/face_068.pnghttps://app.rcfans.com/public/emotion/face_068.png 宇宇宇 发表于 2021-07-18 12:55
真的会玩…想问楼主rey用的什么胎
国产pl的零度轮毂，加上自己设计的碳纤维挡块
