I don't get it if the lower half of the ATV is say 50% and the upper half is 100% what would happen if the low in not 100%? The gov works from the middle to upper range depending on the rpm. It never sees anything below the "V" curve if in idle up conditions, so why does it matter?

Not an expert but I would guess the requirement for 100 ATV would be to preserve resolution. By using less Atv the receiver loses precision

If you have 50/100 for your end points then your throttle setup is completely wrong to begin with.

The answer to your question is resolution but right now, you're not even in the vacinity of a proper setup.

Sometimes it needs more than 50%. Some governors dont use a throttle curve so it wouldn't matter if it is 50%,except that it needs at least 25% for the gov to engage.

He's talking about the ATV and not the throttle curve.

If he's actually got that setup with 50/100 on the atvs then 50 percent on the throttle curve won't have half throttle in any case.

I had messed with the throttle for a half of a day trying to get the linkage right with different arms and such, and it seems the 100/50 was the best I could do. I am using an HS81 on a predator 90.

I guess the answer I was looking for was resolution. The gov turns on and off when it should and it will activate at 25% throttle in normal mode, but if you are in idle up you are never going to see a low side on the curve because the gov is keeping the rpm at your specified rpm, right?

Which gov?

MultiGovs read the throttle curve to lead the throttle requirements rather than waiting for headspeed to drop.

Take a look at this.

Pay special attention to step 36 and the two photos above that paragraph.

There's no reason you can't get your atv's set correctly.

Hmm, I have never done it that way. I will give it a shot. I also didn't think of using a wheel and drilling a hole. I have been using the arms that were on the servo. Thanks
