I just got a stock 450 with align 430 motor,13t pinion. I use a JR 9303 heli radio. I'm looking for a smooth pitch, throttle curve. I like to hover at 1/2 stick. No 3D, just standard aerobatics. Can someone suggest numbers for the curves. Right now I seem to be chasing the controls. Seems to bob up and down with small changes of the Left stick. WLJ

I'd set the pitch curve at 0 - 25- 50 - 75 - 100 on all stunt modes and throttle 0 - 60 - 75 - 75 - 75 normal mode and
straight 80 on stunt 1 and 2.

For it to hover at mid stick set pitch at around 4 degrees at mid stick.

Try this
The throttle curve is just gonna control your headspeed/power. I think you would want high head speed to keep the thing more stable.

Dumb down your pitch range in normal mode if its got sensitive collective.

for throttle in normal on my 450pro I like the following:
0, 60, 90. 95. 100
This way I have mostly full power anything above half stick which is where I spend most of the flight..

I dont use the following pitch curve, nor have I ever tried it but if you want it mellow maybe try this. Start with -2 at low stick and +8 at high stick. This should give you +5 degrees at mid stick which is about what you wanted.
Then just make the graph on your radio linear so you have a smooth transition from low to high stick.
This is just a suggestion for you to try. Could be much better advice out there.

INH expo
I have mine INH on all controls except my tail. Expo is your personal choice. If you want the thing to be close to non modified set up as possible I'd INH all expo.

pitch
I think you're right about the pitch also. I set it per the book. I can get plus/minus 11deg. Got it set now at minus 2/plus 11. Going to get rid of some of the plus. Think that'll help a lot. Thanks WLJ

pitch
Yes thats why I was saying. Pick a range and then make the curve linear. I gave you -2 - +8. That is a 10 point spread so you can have +5 at middle stick. That should get you in the air at half stick for sure. And not be so sensitive after that.

WLJ, the down side of hovering at mid stick is when you do what to get into some 3D or just inverted flying, you'll have to relearn your collective stick placement. I did it the way your setting yours up to start, then had to re-learn my collective stick inputs.
Just me, but I don't like re-inventing how to do something any more than necessary.

Narrowing the pitch range did it. To OLD for 3D. Thanks, WLJ
