I agree if Dave had made clear the IP he was referring to was the cads he had produced already then said something like 'I've got an idea what if we all did this to protect our models etc' then I might have some sympathy.
It seems an incredibly bitter rant with fingers pointing blame at everyone but himself. Is he suggesting that when he was commissioned by various shops to produce models they later dropped him but continued to use his developed cads. Is this true or not or just his perception.
We may never know but I think one of the shops dropped him due to lack of progress.
so much for the announcement but I was right, wrong Scale ,Gauge and Livery for me and my wallet rests easy!
