What are you using the model for? If it's a sport plane, then that's some good advice, but you might want to double check those airfoils at the Re of your actual plane. Some airfoils have nasty little surprises in store when used at the wrong Re, the Seilg 8036 is one of them. The 8036 is common in B class combat planes, and works very well. But it has a nasty stall tendancy when the Re gets a bit too low. We found this out the hard way when people started using teh 8036 on SSC class planes or with smaller tip chords in B class.
