標題: 用媽星壳+LED 燈比 Protofom, Parma 壳跑差幾遠
各位師兄, 請問如 Tamyia TRF-416 用媽星壳 + LED 燈跑同落跑場用的 Protoform, Parma 等, 會差幾遠 ? Setting 是否亦要因應去調校 ?

有無邊位師兄幫到忙 ?

可否舉例講講 ? 例如咩 Setting 會有分别 ? Toe in ? Downstop 等.....

呢樣野好難講喎，有部份殼可能會偏推，有 D 又偏向彎好，但係跑直路有冇咁定，呢 D 係要憑經驗同自己渣法0黎調整

I had some experience to share when I did a comparison in the past.

Situation:
Same track - Old TRC track
Same chassis and electronics - XRay T2'008 + 10.5R brushless motor
Same tyre - Sorex
Basically everything was the same, just the shell was different.

Shells:
- Tamiya BMW 320i WTCC
- Protoform Speed 6

By using Tamiya BMW shell, I can only consider my car was totally undriveable when comparing with Speed 6, at some corners, I can flat out when using Speed 6 shell, but with the Tamiya BMW shell, the car has to be slowed down quite a lot when going into the same corner. Overall, the lap time was at least 1 second slower when using that BMW shell..... I remember that the lap time should be around 13s per lap, so now having 1s difference, the margin is quite a lot indeed.

Can't share settings for those 2 shells with you because I had no interest on setting up my car for the BMW shell, I just had one run and then going back to the Protoform shell immediately.

是売的重量分別或是風速影響 ?

車殼會影響O架車O既風壓,從而影響抓地力.

田宮好多車殼都好靚,但係風壓都好差........變成O架車轉灣時下壓,令架車同車呔唔夠抓地力

風壓唔單止車尾有關,車頭亦都有關.
車尾風壓不足,車行直線唔夠直,會撩撩下.
車頭風壓不足,車轉灣時就好推.......

較為好走O既田宮有燈車殼,真係好少........
冇燈殼O既,就NSX,SC430,F430,我來也,SGT GTR R35都OK好走,但全部都好似冇燈杯......

It's all because of downforce and aerodynamic efficiency.

咁室內場會比室外好好多 ? 改用大尾翼有無幫助呢 ?
