Is there a difference beteewn the throttle servo slot and the Channel 4 slot. Is the throttle servo slot the same voltage as the cyclics or should i move my HV throttle servo to channel 4?

Which receiver?

And yes, there IS a difference. The Throttle channel will run a throttle servo OR ESC plugged into it, when you move the throttle/collective stick.

Channel 4 is usually reserved for rudder, and the device plugged into that slot will respond to the rudder stick.

Unless you can reassign functions in your transmitter, you're not going to be very happy with just plugging stuff into the RX randomly.

I was told if you are not running the governor that channel four will allow you to use the throttle without the governor. I haven't tried it but I had a problem with no throttle servo response while I was using the servo port without the governor.

I use vbar with satellites and no receiver.

You don't know what you don't know!

I have also have the throttle with no response but I am using govenor mode. I am running a futaba with Sbus.

Is the throttle servo voltage lowered in the throttle slot? Why can you not put power into that slot?

Ok i looked at this a little more. The voltage is the same with either socket you use. I did move my throttle servo to the channel 4 out put, and it works great.

On my heli i have it set up so i can control the idle with my throttle curve. I go to the low point and i have it set at 12 so the heli will idle. With the servo in the throttle socket i have to make that number zero and then the servo will initialize like an ESC will. The problem is if you keep it at zero and adjust the idle in a different place you can not use the throttle kill on the radio.

So move the servo to channel 4 and all is good.
