Threats with suing! well he hasn't got a leg top stand on!! he's all talk when it comes to kitting a design. Get a copywright on your design and sue him I say, you have all the proof in black and white! But some how I would think you wouldn't stoop to his childish level!
Besides a local shop has been selling some kind of heli mould that he does, I have seen one and its rubbish. In fact I would think my 10 year old son could create something better with paper mache! I just laughed when I saw the poor quality..LOL
Its a shame because we all had a bit of respect for him to start with until he showed his true colours.
Sorry to go on mate, but I felt the same as you. It stopped me putting detailed build logs for all to see, instead if there is interest I let people have a design to play with
Looking forward to more progress on your Microlight. I am sure Chris and Billy Boy will somehow be constructing very soon....they are like building monsters!
