Building techniques / Re: Control throw measurement.
« Last post by Ken Culbertson on Today at 02:06:50 PM »...you would adjust the bellcrank-flap pushrod length to get a straight-line relationship between leadout movement and control deflection.Not quite although we may be saying the same thing differently. I am not interested in the amount of control deflection only in the rate of turn and the presentation of the turn. My goal is to get it to turn the same amount and same way both directions for a given input. Adjusting the elevator changes the flap/elevator relationship and can cause the plane's AOA to differ between upright and inverted. I am probably in the minority, but it bothers me to have a plane flying noticeably tail low in level flight either direction. It is not a deduction and probably doesn't matter much. Most of this, and the final tweaks, can be accomplished at the handle level but that is the last place I want to make changes other than the spacing to even things out between planes. Addition of the canard on my Endgame design has heightened my awareness of differential movement. It is very effective in guiding the nose throughout the flight (like a horozontal nose rudder). If it is not absolutely aligned with the wing it creates a strong difference in how it turns. Aligned properly, it's rate of turn relative to the flaps rate adds a very simple tool in leveling the plane. Having said all of that, we are still back to the fact that it really doesn't matter much how we get there, only that we do.
