You can actually make it all happen with one channel. You can sequence using the slow function and then just do as in the attached pictures.

Mmm, no you can't!! It looks plausible, but have you tried it for real with servos attached? It doesn't work and it can't work! It will only work if you use slowing at the Tx and leave the weatronic servos running at full speed.

The reason is that Weatronic slows down the servo, not the channel data. The timelines are not the vertical lines Gerhard, they are the horizontal lines. Try it, hook up servos, set the curves as shown in your post, and when you move the retract switch the door servos will not move and the leg servo will move immediately with no delay. The reason is contained in the little green bars, one along the x axis that shows the incoming channel position from your tx, and the one on the y axis that shows the servo position. When you move the retract switch the channel bar on the x axis immediately goes to the opposite end (left to right or right to left). Weatronic does not slow that down. What is slowed down is how fast the green bar on the y axis moves to the new position on the x axis. Look at your door curves. They start at x axis full left, follow some shape and end at x axis full right. When you operate the retract switch the channel data x axis jumps from full left to full right. What y axis positions correspond to those? -100% in both cases. So the door servo sees that it has to travel from -100% to -100% which is no travel at all and it doesn't move!!!!!!!!!!!!!. The leg servo sees its data immediately go from -100,-100 to +100,+100 so it sets off immediately to travel up the y axis from -100 to +100. It does it slowly. What we want is for it to wait stationary for some time and then move rapidly, instead it starts immediately and moves slowly.

So what you need to do is use the servo speed control in your Tx, set the curves as gerhard as shown, and leave the Weatronic servo slowing at Off. That way the channel data on the x axis moves slowly and the servo can follow the curve along the y axis. If your Tx doesn't have servo speed control, you can't do it.
