“Dropped MiG 21 and parts without notice. Can no longer count on Motion to support my models - or my friend’s model. No better than Horizon now. Pity. BTW, if you want a benchmark on how to sunset a model, look at Jan Henselit. His helicopters are expensive, he told everyone in advance that he’d be discontinuing production, but would continue parts support for 10 years. My investment in his helicopters is secure. The numbers might be different for you, the concept could be employed. If you want more input, my fee is reasonable.”
