Gaetan Belanger, the creator of the C420 L-2s wouldn't be happy if he saw that you have his model available for download. That's a model that he sells on his website for profit. I'm not telling you what to do, but if it was my model, I would be upset that it's offered on another site. Just a suggestion for you to take it down.
I appreciate the concern, part of the reason I had not been offering it before was because GB had been selling that particular model. However, the C420 model is no longer one of the 'members only' models that he sells, which is how I was able to obtain it - variations of his C420 model are available on other websites for download with the stipulation that they will not be redistributed in any form for profit, which I am not doing. I have only shared my site with the members of this forum, and I trust no one here is using the downloads for profit.
Since we're on the subject, the only potential conflict I have as far as copyrights and whatnot goes is with the M1, simply because ACR is no longer in operation and has not responded to any inquiries about redistribution. Should a problem arise, I will not hesitate to remove anything.
