NE sometimes supply this receiver without the black cover case. Please do not purchase if you mind.

Since very few dishonest persons tried to cheat us for a replacement receiver with the old one took off from the helicopter, so we would do the followings for prevention:

1. use a camera to record the marks on the receiver (you will see each receiver has different marks and will not be the same) so we will compare the video in record with the receiver returned from customer.
2. use a special "Once Off" leaser sticker to stick on the receiver with a number marked, so we know this receiver belongs to which order.

We would stand firm to Say NO to those cheating persons, and will refuse to do any more business with them. Please be respectful and responsible.
