I use droop when I have weird size rims......I run an X5 with Crono rims , I had to put shock spacers inside the rims and then increase droop so when the buggy is catching air the inside part of the rims won;t hit the head of the turnbuckles.
Is this the Swift buggy you are talking about? I am still waiting for mine. Is the PRO version out yet? A friend of mine who goes in and out of China said that he can get me the PRO version by the second week of January. I hope I get the PRO. This is the 1st time I'll be running 1/8 Nitro Buggies. Thanks
