I would appreciate if someone could tell me the math formula used in installing aileron horns so the push rod is straight when the aileron is at full deflection. I used to have it but it has now vanished. My email address is

Thanks Bill
kemper, unless your ailerons have a pull/pull setup, the ackerman theory is NOT relevant. The geometry principles described in those articles apply only in a pull pull setup situation to keep both cables under the same tension throughout the full travel of the surface
in practice tho, this is not that big of a deal as one might think- cause if one cable become a little slack (the one on opposite side of the cable under load) it is NOT a big deal... all my pull/pull setups are this way with no ill effects, you will find many posts with the same conclusion (do an "ackerman" search)
hope this helps,
