Throttle trim not working

Post by cowboychris »

I can not get the throttle trim to work on one particular model. It works fine on other models, so I know it is not a radio issue. I have the trim turned "on" in the "inputs" screen, but when I look at the channel monitor, nothing changes when I adjust the trim. I can see the trim move up and down on the main screen, and it makes the corresponding sounds at high, low, and center, so I think the trim tab is physically working right. Any ideas would be greatly appreciated.

The trim can be disabled in the mixer as well.

I somehow (not really sure what I did) got the trim to work above center, but it is still not working below center trim. This is important to me because my plane has a sound card in it. I activate the throttle trim until the prop just start to spin, and this "starts" the engine sound. When I bump the throttle trim down, the prop stops, but the sound does not. I need just a little bit more (the sound card is not as sensitive as the ESC).

Thanks for your input!

You can connect the sound card to a different channel if you have a spare one, with the throttle stick as source.
Then adjust it until it matches the throttle channel so the sound starts when it is supposed to..

That is a great idea. Why didn't I think of that. It still doesn't explain the throttle trim, but this is probably a better solution anyway. It will give me the ability to fine tune the sound independently of the ESC. THANKS

And if you use a curve on that channel you could really match the sound to the stick travel.
