Well i have seen alot of custom chassis that have sparked an interest. I now found some plans for them on the internet in pdf and CAD files. These will work perfect for the waterjet. I am going to reduce the length by 40mm so it stays true to the 1/16 scale size. I will take out the 40 mm between the rear shock mount and the motormount. maybe just 25 mm so i can put a bigger motor in it.
*this has been done before by Wiggy Fuzz and the chassis was designed by kazuaki
