So, keeping in mind that I am still a beginner:

~ Build with option A (beginner) with more dihedral with ailerons
OR
~ Build with option B (more sporty) with less dihedral with ailerons

I prefer 3-channel but if you think I really should have ailerons, is it simple enough to convert it to two servos instead of the instructed one servo? If it can be done can someone provide details and graphics on how its done?
