n00bi3 and pitch/throttle curves.
I'm just about done finished building my first heli, a Century Hawk Pro with an OS 32 SX-H, and an old Futaba 6 XHs tx.

I've got all the servos setup properly, blades are balanced and center on the servo throw, pitch runs from -10.5 to 10.5 degrees.

From what I've read on various sources, I'm about to setup my throttle and pitch curves as follows. Keep in mind my tx only supports a 3 point curve.

P1 = Thr 00% = Pit -3
P2 = Thr 75% = Pit +5
P3 = Thr 100% = Pit +9

Think this will be good for starting out before tweaking?

Start with 50 percent at half, tweak from there.Andy

nitro throttle curves are impossible to take a guess at without having the bird on hand.

the best thing to do is set the pitch curve so that dead-center gives you hovering pitch (should be 4-5 degrees on a 30, the manual should give the exact number) and adjust throttle curve until center-stick gives you a good hover (no climbing, no descending, just holding).

75% throttle at mid-stick is almost certainly way the hell too high, on my Nexus with a .32 SXH, i have 35% set for hover position.

If your Tx only supports a 3 point curve, that's perfectly fine. Most pilots only use 3 points unless they are looking for more specific performance aspects on specialty type models like scale. But, for most basic helis and even 3D helis, 3 points is all you need. When setting up a new heli, no matter the size or power plant, e or nitro, its usually a safe bet to go with a 50% middle point. As long as your pitch curves are setup properly you should be good to go. You can adjust your T-curve as needed once you fly it. If your engine is screaming you can always adjust it down a few points or up if your engine is dragging under a reasonable load. I like a little bit higher H/S most of the time, so I usually end up with about 60-70 at middle stick. Sometimes higher for my e-helis. Just remember whatever you set your hover middle t-curve to, try to use the same value for your ST1 and ST2 modes as well. This will prevent your heli from hopping everytime swtich flight modes during flight. Good luck with your new heli, I know you'll have alot of fun with it once you get it up and running good. Mellisa

understood everyone. Tonight I set it up as pitch -3,5,9 and throttle at 55% center stick with idle up matched at 55%. I'll go from there and see what explodes first

Thanks again.
