I have one of the Extras off ebay.Its from a diff seller but like yours has no namebrand or any origin of manafacture.It is my first plane to fly in about 8yrs.I put a magnum 91 2 stroke on it.First off,it needs a computer radio.The instructed throws are a tad slow for even basic aerobatics.I sped everything up a little,now without expo on my radio,it turns like a pylon racer and all you have to do is think about up or down and it s headed that way.Mine didnt have an exit hole for the rudder pushrod and the rudder didnt have a "hardpoint" for the control horn.Servo tray broke loose the first flight and the landing gear mount came out on 2nd flight.With a little going over,it made a decent plane for the money(116.00shipped),just nothing like my old Goldberg Extra.Be sure and add some glue to all the joints you can reach and watch the control throws and they make ok planes for the cost.My neighbor just got the Skyshark Edge.Wish I had spent the extra 100 and got it.
