PR V4R FM retains the main elements of the V3R. With the V4R,
we have added more chassis flex options and quick adjustment design concepts.
Battery Mounting: A change was made to the mounting arm system, which increase chassis flex and also keeps the battery retainment method of the V3R. So using the V3R battery retainer plates, chassis flex can be decreased if needed.
Battery Placement: The front to rear weight can be quickly changed by moving the battery pack forward or back with ease.
Quick adjustments: The new quick access gearbox allows for faster adjustments of gear diff and easy maintenance of ball diffs.
Chassis Design: The 3mm thick chassis has more CNC machining done to create a lighter part along with moving the the car’s center of gravity to a more optimized position.
The PR V4R FM inherits the stability of the previous generation and builds on it. For those with a spare parts bank already, you will be happy to know that instead of a completely new model, we have only redesigned the parts that needed to be. This makes it very easy to upgrade your previous model with the latest parts.
It was necessary to find a better design direction. Although it took a lot of time, we have achieved it.
PR V4R FM保留了V3R的穩定元素，在V4R這版本中我們加入了更多扭動/重心轉移及快速調整的設計理念。
首先，電池的固定改為側向，完整釋放更多的扭動效應，但也保留了V3R的電池固定方式，有二種方式可供選擇。再來藉由可調電池前後位置，讓車體重心的調整更加多元，快速改變前後重量比。至於快速調整的部份，則是把重點放在後齒輪箱，以往更換差速器需要拆除許多的螺絲，V4R則改為快拆式設計，針對不同場地快速更換差速器。底盤選用3mm厚度，並搭配更多的鏤空加工，不僅減少了重量更讓後齒輪箱及馬達重心再次下降。透過更精確的計算，大幅度的降低了整體的重心並更加前移。
PR V4R FM承襲了前一代的穩定性並加以優化。為了讓一直以來的支持者能沿續更多的零件。而不是一年就必須更換一個新的車種，又要能找出更好的設計方向。雖然花了許多時間，但我們實現了～
