By the way, I trust you're familiar with Martin Hepperle's work on model aircraft aerodynamics?

There's hours of distraction there when we should be doing work
I'm thinking of using the MH 33 aerofoil for my twin ... although I think if I can get within a bull's roar of the actual shape, I'll be happy!
Yes I've read most of the info on Martins site. There is heaps of interesting stuff there. He would have published a lot more, I think in the form of Papers, It would be interesting to have a search through the journals and see.
The MH33 section looks like a beautie that's why I chose it for the Dynamite's wing. I've allready got the templates on cad for it so If you want an accurate printout of the shape just let me know, it's the work of moments to scale it to any size you like.
One thing you will have to be carefull with the MH33 is how you do the construction of the wing, it needs to be very strong because it's so thin at only 7.3%. This will be even more important if the model is a heavy one.
