Goldguy,
I never built one , just saw a drawing and neve thought on including or not the flaps ....thanks for that clarificatio. However , for 160mm wing chord substracting 40mm flaps , that is 120mm, then 50% should be 60mm but the step is at 70mm not at 60mm. So i am still lost. I am thinking in modifying a regular airfoil of a Savage Bobber, mi plan is to have a 95mm wing span, but i want to take advantage of a big ailerons , like the Trottle and i do not know if i need to increase wing chore or just increase the size flaps to 25% like the Trottle using the same wing core of the orginal plane. Any advice is appreciated, Thanks |

I have big ailerons because I fly a lot of 3D type maneuvers where the air speed is low and the input needs to rely on the prop thrust.
I then just add an extra aileron servo and change them to flaperons in the TX programming. The size of ailerons or flaps in more about how you fly and the kind of reactions you expect from the control input. I really don't follow any hard and fast rules, if it looks right to me then that's what I go with. I'm not always right and am constantly modifying and fiddling around with my setup until it suits my flying style, which is pretty extreme and or not so pretty at all. |

When it comes to the wing dimensions I tailor them to wing area and wing loading. Building light with a low wing loading is always my goal, because it's the difference between a great flying model and a crappy one.
I always start with a doodle and do the math, then work towards my projected flying weight. |
