So I'm clearly excited for this module to come out and regardless of its performance, will probably add it to my collection. That being said, I'm going to be a slight wet blanket and say I don't agree with HoggitDev not charging SOMETHING for his (or her) work on it. Not only do I feel people should be paid for their work, and it helps add incentive towards further individual development, but by putting this model on the market for free starts an interesting precedent for others. I understand that the OP doesn't want personal profit from this, but it cheapens the market and sets an unfair price point for lesser developed models that the sim could benefit from.
Over the last few years, in my line of work, I've seen how private contractors who market themselves at a price point lower than the established standard, end up hurting the rest of us looking for work.
I'd pay the same for this as I would any individual FC3 model, because that's what its worth to ED and the rest of the developers or potential developers.
Just my opinion, doesn't make it right or wrong, but something to think about...
