このCarreraのスペアパーツは、503018に対応するローター ブレードのコンプリート セットです。RC飛行機器用の交換部品としてCarreraブランドで提供されています。
The rotor blades fit perfectly on my 503018 unit and the material feels sturdy enough to hold up during rough landings. They were easy to install with the included mounting hardware.
Wasn't sure a replacement set would balance as well as the originals, but these dropped right in and the copter hovers steady again. Both blades came in the pack, so I've got a spare sitting in my toolbox for the next crash.
These fit my 503018 perfectly and the blades balanced right out of the package, no trimming needed. Swapped them on in a couple minutes and it's flying smooth again.
