Main Landing Gear retraction link
thingiverse
This beefed up replacement link may fit with a variety of RC planes with retractable landing gears. In this particular case it is used in an Avios C-130 Hercules foamie purchased from Hobbyking. The gear manouvering logic had some built self destruct sequence waiting to happen - and it did, at least in my case. Somehow the gear movement got obstructed (gear is easily misaligned by moderate landing abuse) and this link broke (least bad thing to brake, the gear motor mechanism is strong). This link design is stronger than the original so make sure your retracts work ok without getting stuck, because as I said, this link is strong.
