I purchased the Blade brand aluminum swashplate, blade grips and main rotor hub. After 3 months, I had a failure last night which destroyed the swash and I believe the failure is due to the main rotor hub. The hub has a ball link guide on each side of the part. The space in that guide is tight and simply getting the link through the opening can be a little difficult. Even still, not having as much slop here should make the helicopter perform better. The issue I have is the ball link guide has very sharp edges that were unknowingly wearing away at my ball links. After one snapped (and destroyed the swash plate) I looked at the other ball link only to find flat spots carved into the plastic. It's my fault for not checking the links more often, but a small chamfer on the rotor head would have been nice. If you purchase this, I recommend you do what I have done now and brake the edge of the machining inside the guide. Other than that issue, the part fit well on the helicopter and has proven durable. The aluminum makes this heli really stand out.
