>>since you have the plane in front of you, what aluminum gear would best fit the R.M.D. <<
Walter,
I suspect that most any aluminium gear would work OK. Just have to make sure that the stance is wide enough (I'll have to get out an measure to give a number - I'll do that tomorrow).
I was looking at doing the carbon gear, but I suspect, as I've been checking things out that the cost would probably be prohibitive. I do mostly prototyping molds for personal use. They work fine for two or even three pulls. But to do 20+ sets, I'd need a production mold. They can be a bit steep to make. So, I'm checking on that now to see if it's reasonable to do.
