Swash plate

[ItalianHeli]

Hi guys! I am bulding my new 250 and I have noticed that at full throttle my swash plate is touching with the top part. What is the best way to avoid this problem? Should I shorten all three servo to lower the swash plate? Please advise. Thank you

You just need to move the pitch setting on the swash mix down so that doesn't happen.

Hi! So if go to the CCPM menu, do I just lower the pitch at middle stick until the swash plate is no longer touching? If I do that will that affect my full throttle pitch?

There should be a menu that has aileron, elevator and pitch mixes. Something like 60% 60% 60% is default on a DX7 I believe. You'd change the pitch one to maybe 50% or something so that it reduces the pitch range.

But I think I set mine up with link lengths per the manual, and didn't have any binding problem with 60% mechanically.

the pitch percentage will shorten or lengthen the entire travel across the whole stick range.You need to set the pitch% for like 10 or 11 % pitch pos-neg.Then if your hitting the rotor head or bottoming out the swash,you need to adjust all 3 swash links to address the problem.Center stick should give you 0 %,with the mixing arms and washout arms level..
