I recently purchased 2 trainers Sports Cub s 2,, being a very experienced pilot ,I was so very disappointed at the quality of the product, , on a no wind day I decided to take off after the craft was Binded, response on the ground was OK, but after take about 40 yards away the aircraft was uncontrollable and just kept flying never to return, no doubt back to China, and have since met others in the club who had same problem , so I have returned the second craft back to RCMA for refund, and I am asking you to refund me , for the one that flew away, as there must have been a fault in the aircraft, , as its a total waste of my money, , and had to pay $66.65 to return second one.. not happy.
