I know MRS4 is very old car...but still have a lot people like to play MRS4 at Europe and USA...I post some picture here is want to share some chassis that I think is nice at the market....
p/s some of them already discontinuos
Sorry,I also don't know at HK where can buy,because I'm not from HK...but i know one friend at HK got sell second hand one.I always buy things from him...you can find him...as I know he still got NIB penguin RC chassis shown on first picture for sell..
Actually M18 and MRS4 both need many of modification....just MRS4 need more alloy part than M18...and more expensive...
If you using original HPI part and didn't do any modifications...the car won't run fast...but if you change to the ratzas,penguin RC or motek chassis...i guarantee you.. the car run fast like 1/10 touring car with 23T stock motor...
maybe u should show us the original chasis as well...hhaha ~
your microRs4's are so different, don't even know they are all microRS4 if u don't tell me.
