Doing them all is a big order but we'll get there.
The thing is that say we do a pivot fin for example. there's no point in doing just one size with one foil, Instead we do six sizes with three different foil options, that's 18 fin drawings and 18 times whatever test prints and bench test victims. It all takes a lot of time. with side fins it is even more complex due to different fin tabs and cants, plus some fins need double and single foiled options.
So far we have about a hundred different fins but it doesn't look like that many on the shop because some are just drop down menu options. It's pretty crazy but the ability to have a large variety and custom fins is one of the main advantages of 3D printing.
Hence my desire to get help choosing the next one.
well that makes sense. With the log fin you really only need one size and foil though, right?
I say do that one or the single fin, just for the style factor.
With the log fin a 10" and a 9" would suffice although I'll do some smaller ones as well, they could be good for mid length pintails of the early 70's variety.
Better foiling is going to make a big difference on the log fin, most of them are very thin for their base and chord length, ( due to the usual 10mm panel plus long base length) and wind up being pretty flat sided. Some makers ( Tom Wegener and I think Jim Phillips for example, typically those with a wood core are thicker) make them thicker with a nicer foil, but overall they are a type which deserves a good foil to get their capabilities shining through. They tend to be dismissed by the 'HP' crowd as prehistoric rudders but we can make 'em rock.
So, why not go the whole hog and do them with three foil sections, namely Eppler168, RAE102 and NACA16-012 ? We have them loaded up already, and it's a buzz having the choice.
The log fin would be sweet in a root beer colour, we have to order a swag of material to get a new colour though.
