On Revision 1 of the Goblin, the Credits was big and bright too see on my website! On Revision 2, we changed the physics completley and doing them from scratch, cause simply said there were not even close to a real helicopter. Mostly because of missing weights and too much gain and things like that. So nothing is left from your work in any of my helicopters.
Don´t get abused...I´m just doing that kind of stuff that you also wanted from me. Remember as you said I can use youre physics, but a small credit would be nice. I have that PN still in my inbox! So don´t tell me what to do Mister Hover!
A Sound Engine is also lots of hours finetuning work and not a small tiny thing! Recording, Editing and stuff like that.
