Hey guys,

If you can help me out it'd be great cause i'm stumped.

I've got a Trex450 SE v2 with an Hitec Optic 6 radio and for some damn reason my pitch curve seems to be mudled. In normal i have it set in my radio to

50 50 50 75 100

Now by actually watching the swash it seems like it goes like this

65 50 50 75 100

It actually goes down before it goes up and i can't work out why, it didn't always do this i've just noticed it after coming back from a break.

Any ideas????

Thanks
Jeff

I am not familiar with that radio, but have you tried to move the first point to like zero? Just to make sure you are in the right menu?

I don`t know about Hitec radios , but , A pitch curve should start at a low number at low stick, 0% , (negative pitch, 11-12* degrees), 50% at center stick( 0*degrees pitch) and then at high stick(100%) around 11-12* degrees pitch???? with a straight linear curve.. This is kinda how I do my pitch curve? KIND OF ??

Sorry guys i worked it out, the optic 6 has little adjustments on both the left and right hand sides of the radio. The one on the left affects the pitch curve and the one on the right affects the throttle curve.

If a dial is up the corresponding curve is modified to be slightly raised in the middle with the affect diminishing to zero at each end of the curve. And likewise is the dial is down the curve is reduced in the middle and not at the ends. My pitch dial was down so my programmed curve:

50 50 50 75 100

was made so it was more like:

50 45 40 70 100

Anyways it caught me so hopefully this will help another confused optic 6 owner. Cheers Jeff

PS this is only my normal curve my idle up curves go from 0 to 100 and therefore the effect was less noticeable in those modes.

DOH... yes I remember these and did not like it. I think you can disable them.
