Be warned that the whole series of 80XX airfoils MUST be made to the finest tolerances to see any difference between them. Thie means a fully sheeted wing or better yet a vacumn bagged glass and foam type. And this assumes you can cut the cores or ribs so that the final shape is within probably 7 or 8 thousandths of an inch at any point and about 1/2 that for the first 1/4 of the chord.

For the usual 4-40 or 4-60 type open rib construction you are wasting your time using something this high tech.

Sorry for wasting the bandwidth if you already knew all this and planned on following through properley.

In any event I doubt that you will gain much by using such an airfoil on a power model where the performance gains over the usual "Florsheim 9%" will go largely unnoticed thanks to the engine on the front. These airfoils are really meant to shine on sailplanes where every last fraction of a percent counts.

If you're looking to experiment on a model of that type then I would suggest going for either a true Clark Y for slower flying or a true symettrical airfoil for better stunts. Or experiment with high lift devices like proper flaps and/or leading edge slats. Or how about a very high camber airfoil that isn't too critical to covering sag like a Gottingen 500? That would slow the model down. Perhaps add a camera and load bay for lifting things?
