Help choosing Airfoil for 60" DS Plank


Hello All,
Ive been having a great time lately with my JW's but i feel like trying something a little different. Ive scaled up a 48" Zipper to 60" and cut the wing and fuse planforms last night. Im now ready to cut the cores. The wings are being build out of high density styrofoam and the fuse is cut out of EPP.

Ive basically narrowed my choices down to two, possibly three airfoils. They are in order of preference at the moment.

- EH-2010
- MH 45
- MH 61

I believe these are all quite good plank foils. I need some help to make my final decision. Can anyone tell me which one would be the better choice. Keep in mind this is being build mainly with DS in mind.
The original Zipper uses the EH foil however planes such as the gulp use the MH foil. Both are great performers so im not sure on what the difference is.

Any help in choosing the best foil is greatly appreciated.

Cheers Grant

Grant,

What happened to your plan for a more conventional DS design? I saw you post some info about that in some other forums, but not on RCGroups.
