The solution is quite easy, and you almost resolved it alone at 2:20. It's all about geometry, and especially the angle ratios! To be more specific, you only have to find the ratios between your throttles. So, while you push full the first one which may be at 70 degress, the second should be at 90 degress. Here, you have the ratio: 90 / 70. For every 1 degree at first throttle (70 degrees), the second one (90 degrees) goes up to 1.28 degree. If you first throttle turns up to 30 degrees, the second one should be exactly at 38.57 degrees. If you want to combine three of them with angle multiplication (for example) 70, 90 and 110, you do the same math. 90 / 70 (first & second throttle) and 110 / 90 (second & third throttle) Love your videos!
