Evaluating Cyclic Integral (I-Term) Limits on Your 550

Locking in Profile #3 is a massive milestone! Looking at your new configurator screenshot, your current Roll and Pitch Integrals are sitting comfortably at 160, while your Yaw Integral is pushed up to 280, reflecting that high-persistence holding philosophy.

On a 550mm helicopter, pushing the cyclic I-term much past 160 to 180 enters a zone of diminishing returns and potential instability:

• The Sweet Spot: Most high-performance 550-class setups top out around 150 to 180 for cyclic integrals. Because a 550 is relatively light and agile compared to a 700, it doesn't need massive integral memory to force the disc to hold position against wind or heavy aerodynamic loads.
• The Risk of Going Too High: If you crank cyclic integrals up into the 200+ range, you risk inducing integral windup. This manifests as a spongy or delayed "bounce" back to center after a heavy cyclic stick movement, because the controller takes too long to bleed off the accumulated error memory.

Since Profile #3 is already feeling excellent and tight, leave the cyclic integrals right at 160 (or test a very conservative ceiling of 170-175 max). If you want to chase more of that locked-in feel moving forward in your other profiles, you have much safer, more responsive levers to pull—such as minor adjustments to your 120 Feed-Forward or fine-tuning your B-term Boost parameters!
