I will post in this section unusual or special function that can be implimented when using U/Tronics Control units.

Add low idle speed adjustment and Kill Switch.

Now comes the stupid question. When using your system along with one of the slide pots that you provide on a full on/off mode (flaps, throttle, etc.), what position on the servo does full off on the slide pot represent? (My God, that is 36 words in one sentence). As you can tell, I am struggling with what I am trying to say. I just bought a servo driver. I am going to use it to properly set the servos in my next plane. One of it's functions is to find the "center" of the servo sweep. It also can, of course, run the servo from one stop to another. When I set your slide pot to off, what will the position of the related servo be? Will it be all the way to one stop, or will it be centered? I know, plug it in and find out. But I am in the design stage now and the correct answer might help me make some decisions while it is just on paper. Thanks for your help as always.

The Slide pot or a rotary pot will move the servo from near one limit to near the other limit.  The same thing happens with a switch controlled function.  The servo will move from one end to the other.  The center of the range of adjustment of the pot will be approximately the center of the servo travel.

You don't SIR an Airman First Class.  LOL

Now it is different with my oldest son, They Call him "Sir" or "Colonel" because he is a Lieutenant Colonel in the IL Air National Guard.

How to connect one U/Tronics Control unit output to two ESC's:

Note that in the attached drawing the power for the Decoder is provided by the lower (# 1) ESC.

A suggested safety switch for dual engine models.

It prevents ground loops on takeoff.

An alternative would be a lever that ties the throttle arms together until you mechanically disengage it.  That way you don't have a 'bump' in the throttle setting of the 'off' engine when you flip the switch.

Kinda like how tractor steering brakes work, for those of you who've driven with them.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

After a discussion of the effect of the Throttle End Points on the operation of Electronic Speed Control (ESC) for electric powered models the attached circuit changes were recommended.

I have also included how to add an Engine Kill Switch for I.C. Engines only.
