I just replaced my stock arms and suspension with the aluminium customized arms from eBay.
1. Problem 1: The pins provided don't secure the arms very securely unlike the stock arms. Stock arms come with a long screw that you can screw to the chassis. Aluminium upgrade just comes with a pin. It does come with a few snap-on stoppers for the ends of the pin but those provide no use actually. Anyone encountered this similar problem and how did you fix it? Now, the front arms especially are wobbly at the joint stock arms were rigid. I bet when I run the car, it's gonna be worse than stock.
Problem #2: I donno if this problem is caused by the aluminium upgrade, or the suspension or a separate problem altogether, but after I replaced those 2 parts, my car can turn right but not left. The range of motion to the left is heavily hampered. I checked the side trim on the transmitter and it's not set to the right. Even if I side trim all the way to the left, it just won't budge. I took off the wheels too to see if it's obstructed or anything but couldn't find any physical obstruction. When I manually move the front wheels to the left, there is a lot of resistance and the movement is stick (means the wheels wouldn't wanna return to centre position on its own after I release the wheelie on the transmitter. I figure there must be an obstruction of some sort. Can anyone offer any advice on this?
Appreciate it much!
