I am sorry but you clearly have absolutely no idea what you are talking about and are giving out erroneous information.
You clearly know nothing about integral wind-up, PID tuning, closed loop feedback systems or even the cause of rolling shutter or you would not make statements like "The main cause is unsmooth movement". I nearly deleted your post outright since it contains so much bad advice in there
I cannot stop you posting such utter rubbish on here (well I can, I could simply delete your posts) but I will leave it up to individuals who's advice they wish to follow.
Anyone reading this thread please be advised that:
1. Altering your gains without an understanding of what and why you are doing so will dynamically affect both the aircraft's stability in differing flying conditions and will alter its characteristics as to how it actively stabilizes and adjusts its attitude as well as altitude hold.
2. Dynamic breaking can be adjusted and will alter the force at which reverse emf breaking is applied through the esc's - however, it will dramatically change the 'stopping distance' once you let go of the sticks and this can catch people out if they are inexperienced or have not made several test flights and got used to their breaking adjustment.
3. Rolling Shutter (Jello) can not be stopped by dialling in an exponential value into the remote control. The effect of an expo adjustment is to make the centre stick movement non linear. It effectively 'dumbs down' the central part of stick travel - It has zero to do with alleviating resonant frequency or high frequency vibrations transmitted through the airframe or vibration of the camera caused by wind which coupled with higher shutter speed emphasize the jello effect during fast lateral movement.
I would urge all Inspire owners to think very long and hard before adjusting their gains or dynamic breaking since your flight characteristics WILL change. The SIM is OK for what it is but it is not 100% reliable for simulating all flight physics.
Machoman's advice to "Play with the gains" is irresponsible and I do not advocate that line of action especially if you are searching to alleviate/mitigate rolling shutter/Jello
I would hope by the sheer amount of advice I have given out on this forum that I have demonstrated I have a reasonable understanding of not only the Inspire but multirotor platforms in general. At the end of the day, everyone has their own Inspire and they are free to follow what advice they want to but please be mindful of the above.
