TAMIYA TRF421 SUSPENSION PROBLEM

The original ball joints movements are normal and smooth if didn’t mount on to the bulkhead. But the arms will be stuck after screwing tight on the chassis.
Solution: Using a larger ball head 5.2mm (original is 4.7mm actually) to reshape the plastic part. Freely suspension movement after done of it. I hope this video could be help you too. 😉

This kit just a hype. Better buy the original Mugen Seiki Mtc2R

Common Tamiya. $600-$700 car. And people have to purchase different parts to make it work properly. 😞

Well, I will say that the extra cost in this issue could be counted as the expenses on tools like ball head reamer. You paid $600-$700 also need the tools to assemble it. Right?
