重回短卡坑之:udr还是莫哈维?四驱还是两驱?高重心还是低重心?金属还是尼龙?

18年由727短卡入模,最近重新入坑短卡,海鲜市场剁手入了几台二手短卡,基本覆盖了上面的车型,索性拍了照片,进行了基础的对比,希望可以帮到还在纠结的模友。本帖分三个部分,主要是提供一些客观的对比材料,也会加一些个人主观的评论(很主观,不喜可留言喷,哈哈)。

一、udr还是莫哈维
二、slash(包括山鼠)选四驱还是两驱,高重心还是低重心
三、金属底盘还是尼龙底盘

一、udr还是莫哈维
1/7比例永远绕不开的话题,涵盖几个子话题:后直桥还是四轮独立悬挂,耐草还是姿态,traxxas还是arrma。先上图

客观数据上,两车尺寸相当,最大的差别有两个,除了众所周知的结构(直桥短卡结构可参考易控短卡的帖子),还有重量。

图中的udr基本原厂,更换了原厂尺寸的金属舵机和max6rtr电调,重量达到了7.12kg,莫哈维在更换尺寸更大的了4985电机和max6电调(原厂是4274和max8级别)后,重量仍只有5.95kg,两车重量差了1公斤以上,为啥莫哈维相对udr耐草,轻是很重要的原因。

另外一个差别是悬挂行程,图中自观。

主观评价上,个人会更喜欢udr,主要原因几个:1、仿真结构,有原型车,可静可动。2、换电池不用摘车壳,这个意味着各种灯和心情件可以往上招呼,布线,不需要考虑更换电池的时候灯具接线问题。3、个人觉得其实udr还挺耐草,原厂舵机6S时候爱坏,其他的你不撞其实也没那么容易坏。

二、slash(包括山鼠)选四驱还是两驱,高重心还是低重心。

这个也是热门话题,还是先上客观资料

1、四驱低重心和四驱高重心对比
顾名思义,高重心的底盘离地更高,原因是高重心底盘前后差速器下沉,低重心则是一块平板。

两车重量上,由于图中的slash使用了尺寸更大的无刷风扇和散热,车壳进行了补强,所以会重一点,同等条件应该差不多。

补充一点:都说山鼠727copy了slash,网格点说是copy了slash的四驱高重心,本人没有入slash四驱高重心,所以用山鼠代替,结构一样,做工会差一点。

2、两驱高重心和四驱高重心对比

两驱高重心同样采用下沉式差速结构。两车最大的区别,除了驱动方式,还有底盘布局,两驱和四驱完全不一样,两驱的电机是在尾部(重心靠后增加后轮抓地),电池则在正中间。同时,两驱的前避震架倾角也更大,四条摆臂,还有前转向机构也不一样。

两驱和四驱配件可以说基本不通用。

重量上,应该差不多,图中两驱车型车壳做了补强,升级了1 模钢大齿和电机齿,所以略重。

3、主观评价:四驱好操控很多,特别是低重心车型,即便是柏油路这种高抓路面也不容易翻车,动力可以比较彻底释放。

两驱不好操控,新手慎入,容易劝退。

两驱的好处是结构简单,玩沙,玩土,玩泥之后,好清理;前后轮子可以搭配不同直径,外观造型可塑性强;更省电,电池续航更持久。

4、新手入模建议四驱低重心车型。

5、关于山鼠还是slash。新手建议全新山鼠或者熟人二手slash,体验应该都不错。二手山鼠慎入,暗病多,容易劝退。不差钱直接新的slash肯定最好。
三、金属底盘还是尼龙底盘
独立悬挂的10车短卡可以分两大类,一类是以traxxas slash为代表的尼龙车架,一般都是厂家专门设计开发的,特点是轻盈,尼龙底盘。四轮尼龙传动,前后差速加中限滑结构,最高适配3S动力。另一类是8车电越演化过来的,特点是硬,金属底盘,四轮金属cvd传动,前中后三差速,可以适配3S以上动力,比如k1短卡,tekno410.3,鸿诺,禾宝等。

图中甲壳虫是我用鸿诺x3E电越自己改的,相比slash,车架会粗壮很多,供参考。正规厂家8越衍生的10短卡会在避震,避震架,前后防撞等进行一定的改动。重量上,由于甲壳虫用了4S动力,会偏重,同等电设下,应该金属底盘的短卡车型也会比较重一些。

主观上,个人会比较偏爱轻盈的尼龙底盘。或者直接用电越换壳,上4S动力。金属底盘的10车短卡,个人觉得强度上不如8越,重量上又没优势,比较尴尬。以上是个人利用手头的车型,结合自己玩车的经历整理的一些材料,希望可以帮到打算入坑的模友,也欢迎老玩家交流。

udr重,起伏路面小飞可以。太高的话不建议,短卡本来不是干这事的。实在王飞可以考虑莫哈维。udr结构熟了以后,有电动螺丝刀其实挺快的。

udr全拆还是很复杂,但多数易损件,都比较容易更换,基本上底盘打开就能换。
