12mm Metal Rotorhead Swashplate 3-Blades 4-Blades 5-Blades for 700 and 800 Size RC Helicopter Rotor Heads Parts

I purchased two Roban, 5 Blade Main Rd. or heads I was 3 different tracking numbers all three showed not received from shipper and then all of a sudden UPS label shows up and shows delivered. However, I never signed for anything nor did I ever receive anything. This was a 100% loss for me. Please beware of dealing with China they took my money did not offer a replacement. I did not want to refund. I just wanted to product that I paid for and now I am out. $611.00 and now afterwords communicating with the seller all I get was you have to handle this yourself so I asked why do I have to do this? I paid you you did not deliver the product and it just keeps going round and round so please do not buy from these people. They are not honest people.
