| Do polycarbonate body shells become brittle or turn yellow with age?
Hey guys, I wanna start off by apologizing if this is in the wrong section. I wasn't sure if I should post this here or perhaps in the "Newbie General" section? Anyway, I've been in the RC hobby on and off for the past 15 years or so. One question I've always had lingering in the back of my mind was if polycarbonate aka Lexan or Makrolon became brittle or turned yellow with age like some other plastics? |

Yellow no, and the windshields are still clear. My older shells usually get replaced so I’ve never had any get brittle, even storing them in a hot environment here.nothing older than four years old Hang up and Drive | |

Just like everyone else, no I haven’t had any problems. Only time was when I just barely cut into a corner, and it ended up cracking and even breaking apart deeper into the body, but like I said it was my fault. Sent from my iPad using Tapatalk |

I still have bodies in my basement that are 20+ years old (RC10GT and Inferno MP-5). They are painted and stored in a cool dry place (my basement is dry). No yellowing or cracking that I can see.

The hard plastic parts on the OG buggies are dramatically more fragile than they were back in the day. No yellowing has occured | |

I have a Yokomo s14 silvia body still in package not painted yet. Bought it back in 2008 amd its still clear and flexible. Been keeping it in a big green rubbermaid bin. Seems ok to me but I wont know fore sure until I get a RWD drift chassis amd actually attempt to paint and mount it. |
