改装小清单https://app.rcfans.com/public/emotion/face_022.png：
1. 田宫攀岩胎 #54117

其实田宫cr01的结构真的非常适合攀爬，比如： 粗壮的铝合金梯形大梁，马达下沉设计降低重心，可锁前后桥，行星减速波箱（扭矩放大）前后转向，蟹行，以及足够的悬挂行程

改进的思路就是，既然已经不求速度了，那么就继续“摆烂”，进一步降低速度，放大扭矩https://app.rcfans.com/public/emotion/face_666.png

另外一个槽点就是原配的开放式齿差，这个设定对攀爬来说是无用的。虽然可以通过几米螺丝锁定，但是强度存在一定问题。

这个问题通过op 54108解决，替换原有的差速器，直接刚性连接左右半轴：

最后选用1080电调搭配这颗低扭马达，目的就是使用DEO这个功能，微小的油门行程就可以触发马达输出扭矩。 这个功能我还没研究透是如何实现的，但目前看确实非常好用https://app.rcfans.com/public/emotion/face_022.png

其实不是马达波箱下沉设计，而是大梁设计太高了

相对位置是下沉了，你可以说大梁高，也没毛病https://app.rcfans.com/public/emotion/face_018.png
