Way back in the '70s the SIG CADET was THE Trainer. We flew them 3 channel, no buddy cords then, and the ''...grab the transmitter...'' was the instructor way.
One of our club members had one that he had on consignment to sell. He brought it to a club show-and-tell, a public event where people came to see what RC flight was about. He had it set up on a buddy box and was putting people up with it. Without exception, everyone that flew it, well, flew it. It's a wonderful trainer, no doubt.
