I was able to adjust my Specter 700V1 and Nimbus550V2 helicopters better than ever before with V4.0. The helicopters fly precisely, with one exception. I can't get to grips with the Pitchup Compensation parameter, which I had never optimized before. During fast pitch movements while flying fast and straight horizontally, the helicopter makes dolphin-like movements. The tail lags behind by about 5 cm. This should be exactly the situation that, according to the description, should be remedied with “Pitchup Compensation.” The problem is that the effect remains roughly the same with every Pitchup Compensation value. Only when the Elevator Filter is at maximum does the effect become less pronounced, but with a soft feeling in cyclic pitch. That is not a solution.
Both helicopters have fast MKS servos and all other parameters are close to or identical to the recommended default values.
Please help: Pitchup Compensation

Hello,
Changing Swashplate - Integral could help. It could be related to swashplate centering too. However we plan new update very soon that should further improve it and completely resolve the issue.
Interestingly our other pilots with same helicopters have no issues. But blades and other thing could be related too.

The fact that it is not noticed so often is probably due to the fact that most Spirit pilots fly more towards F3N - in the admittedly much smaller group of F3C orientated pilots, the Spirit is unfortunately almost not represented at all - which I think is a pity.
What improvement does the update bring so that this behaviour no longer occurs at all?

Hello,
the upcoming update has all sort of improvements, mainly for Elevator, lowering servo consumption/load/temperature. And also adds new features such as Scorpion ESC Setup for Wave and support for new JETI sensors and small tweaks.
We are working closely with top pilots to reach perfection. I think we reached this goal now and we have to test with as many helicopters as possible.
