Can someone walk me through setting up a throttle curve on my 9C?
 
My idle is at 2000 rpm and my high end is at 11,400 rpm. Now I am asuming I want to use a program mix like 6 on my Futaba 9C and set it up throttle to throttle. Now what?

I'm confused. What exactly are you trying to accomplish? Throttle curve is used to deaden the throttle response around 1/2 throttle to make hovering maneuvers easier.

??????????????? are you thinking about using expo so throttle responce is crisper???

I guess I was thinking of setting up a linear throttle. I am developing most my power at half throttle and above and I wanted to say have the actual midpoint of the rpm range actually be at half throttle on the stick. I messed around with it for a few minutes though and think I just fugured it out. I think if I find the difference between the high end rpm and the idle rpm then divide by four, that will give me the number to add to the idle number to find 1/4 throttle rpm etc. Then I can just use my five point programming mix to dial in each rpm setting at the disired points. Does that make sence?

Yes, that makes sense.

If you are not using channel 8 right now, you can plug the throttle servo into receiver output #8, then go into the THR-NEEDL screen and you will see a pre-programmed curve. Turn the MIX (ON). Set point 1 at 0.0, point 2 at 35.0, point 3 at 70.0, point 4 at 90.0 and point 5 at 100.0. That should give a really good starting point and you can fine tune it from there.

If you are already using ch. 8 for another function, than you will need to do a program mix. Which, it sounds like that's what you are already doing.[8D]

Ya, the way I'm doing it worked out fine. Now I just have to stretch the mid range out a little for better control in hovering.
