What's included in the stainless screw kit for E-Flite Blade 550x Helicopter BLH5525?
Every RCScrewZ stainless steel screw kit for E-Flite Blade 550x Helicopter BLH5525 includes a model-specific mix of socket head, button head, flat head and set screws, plus matching nuts and washers—with extras of the most commonly used sizes.

Which bearings are best for my E-Flite Blade 550x Helicopter BLH5525?
For E-Flite Blade 550x Helicopter BLH5525 builds, RCScrewZ kits use precision metal-shielded bearings. Helis are typically flown in cleaner environments, so low-drag metal shields give smooth rotation and consistent head speed without the extra friction of rubber seals. We recommend keeping the model away from heavy dust and moisture and cleaning bearings as part of your regular maintenance.
