Apology accepted, Bob. I was just reacting to so many thread submissions where someone suggests something and someone else comes back putting the suggestion down, even though they even sometimes state that they do not own the equipment they are pontificating about. I have lately become excited about using the logical switches because I have just learned how to use them and they seem very powerful and slick to use. I created a throttle lock off which needs the throttle off, then Switch H held down for 0.7 sec. before it engages and disengages because my first throttle hold bit me. This was a three liner in logical switches. I have emulated a "bang bang" single channel escapement with the logical switches, a very neat programming exercise, although likely I will never control my Radian with it. It will be fun to show the 88 year old at the field the result. It should take him back to 1956. Regards, Calvin

You don't need to put down logical switches just because you Know another way. OpenTX provides lots of different ways to do things. Logical switches are there for our use too, and it can be fun and instructive to make them work. Maybe, after learning to use them to solve a simple problem you will be able to apply them to something more exotic where they are the best tools to use. Kevin. I would suggest you try both suggestions and go with the one you are happiest with. Someone else on the net may even suggest something different which would be worth a try too. Best of luck.

Hello Kevin. I would think this would be simple to do using the Logical Switches. Set one logical switch a=x Ch5 +100 or whatever the value is for full up This will cause a Logical Switch Flag to SET when gear value is +100 Then put a Mix in Channel 8 to turn the lights on when the Logical Switch flag is SET. Likely you can use a MAX source to do that. You might like to use a>95 (or your equivalent) to provide some wiggle room. Obviously your settings and directions of travel for the values will be particular to your aircraft. Good luck. I will be happy to answer questions if this is not clear.

I saw the article in the RC Soaring Digest describing how it was possible to program a single channel control emulation in the Open TX Taranis. I did not find the instructions for this at the time so this gave me a challenge. After playing around with the Logical Switches for a while I was able to come up with a simple alternating Left-Right-Left-Right Rudder like a simple escapement action. You first move the Rudder stick to one of its extremities, then return it to centre. Then using the Trainer Switch (SH) everytime you pull it toward you and hold it, the rudder will move to the side opposite to the side it was for the last control action. Releasing the switch will return the rudder to centre. Have a look. I would be interested in comments Single Channel Rudder control This mix creates a side to side, alternating Rudder action like a simple escapement output. The ordinary stick control of the rudder, elevator and throttle is always available as well. To start, move the rudder control (For a Radian using Right stick Left Right for Rudder) to full right or left then release it. Then pull Switch H toward you to move the rudder to the side opposite to the side you initialized it to. When you release the switch the rudder will return to center position. Rudder Mix 1 Rud Weight (100%) MAX Weight (+100%) Switch (L8) MAX Weight (-100%) Switch (L9) Set Rudder side to side distance by adjusting SERVO Min and Max L1 |a| <x Ch1 3 L2 a<x Ch1 -95 L3 a>x Ch1 95 L4 Sticky L2 L3 L5 Sticky L3 L2 L6 AND L4 L1 SH-Down L7 AND L5 L1 SH-Down L8 Sticky L6 SH-Up L9 Sticky L7 SH-Up Flag L1 is TRUE when the rudder value is centred ( |a| < 3) Flag L2 is TRUE when the rudder value is -100 ( a< -95 ) Flag L3 is TRUE when the rudder value is 100 ( a> 95 ) Flag L4 is set TRUE when the rudder value is -100 (originally set by the rudder stick, but later by the alternating action). L4 is set FALSE by the rudder value changing to +100. Flag L5 is set TRUE when the rudder value is 100 (by the alternating action). L5 is set False by the rudder value changing to -100. Flag L6 is TRUE when Rudder is centred AND Rudder was last at -100 AND Switch SH-Down. Flag L7 is TRUE when Rudder is centred AND Rudder was last at +100 AND Switch SH-Down. Flag L8 is toggled TRUE when L6 is set TRUE. (+100 added to Rudder value in Rudder Mix) It is toggled False (Rudder value set to default 0 with release of momentary ON Switch SH) Flag L9 is toggled TRUE when L7 is set TRUE. (-100 added to Rudder value in Rudder Mix) It is toggled False (Rudder value set to default 0 with release of momentary ON Switch SH)
