where to buy 501x parts

[B44&501xRacerEX]

Bad weather at the distribution factory..
I wont be getting my 511 body and wing this week at all.
I was bummed out, but I'm in no hurry...after all indoor season is 5 months away. It's currently outdoor season.
But some stuff came to the shop today so I went and picked it up.
My local track is having a FREE RACE this weekend...



"LIMITED EDITION" I was like what? It's just a black pulley...for a 501x.
O-rings gotta have them. My current ones are still ok, it's just good to have spares.
