Everything on the Sky fly is original except for the control rods and hinge tape.
I have had no problems with the radio.
The guy at the local hobby shop ( Porkeez House of Hobbies in Sebastopol, CA ) found a sky fly in a tree. He found out that I had one and gave it to me (pays to shop locally...)
I am going to perform the same conversion on that one and I will take pics and post soon.
