Throttle curves... have to do eith hovering what?...

[Jason Michael]

Would someone please explain to me why I would need a throttle curve and how I should set up fpr basically just hovering and flipping around.
Keep in mind I am a covert (kind of) heli guy. I understand that with my heli and without a governor to control the head speed i would have to set the throttle tp be opened at a certain pitch the blades were pulling so it would not bog or oversspeed.

But maybe I just confused myself

Gas engines tend to be non-linear in throttle response.
1/2 open throttle butterfly doesn't necessarily mean half the available engine rpm.
There are lots of ways to get what you need, and most do it the way that suits their flying
style.
Some divvy up the the engine rpm over the stick range using the idle and wot rpm as a reference.

Others like to keep the throttle stick around the middle when hanging, torque rolling etc, and
tailor the curve so moving the stick a little, doesn't move the plane alot, either up or down.

Each plane is different and may demand it's own set of rules.
Different weights, behaviors, props, and even wind conditions all make a difference depending on what
you're doing at the time.
It's annoying when one click of throttle either way makes the plane climb or fall.

The other thing that is VERY helpful is to set up your linkage properly.
I run my ATV to it's max, put the linkage in the closest arm hole at the servo, and connect it as
far out as I can on the throttle butterfly. It that is too much throw, I adjust it out mechanically, not
with the ATV. The ATV gives you the best resolution your radio has to offer, so why not use it?

Although it may sound complicated, it really isn't.
Try it a couple of times if you haven't already.

Not sure if that's whay you were after, but there it is.

Take care

Bob hit the nail on the head with setting up your linkage correctly. Also paying close attention to getting as much resolution as possible. I find that when I do this, I have no need for a throttle curve. Granted, I dont run "open" mufflers, but on my cans and pipes, I havent run into a need. Perhaps it is slightly different on mufflers.
