I was told the Rolling Shutter or  Jello effect is not an issue due to the larger sensor??   I have been using the 3 Professional and you need a ND filter to keep the shutter down to 50FPS for video.   Will upgrade to 4 Advanced so are you guys using filters or not needed?  Please everyone pipe in!!!!
Thank You

you ll need use ND 4 , 8 , 16 OR 32.. depends the situation

iv never used filters with the p3p or the p4a but this is interesting topic
as I eliminated jello on the p3p two years ago by changing the rubber dampers
and lock pins on the gimbal but again the bird has slight jello when flying forward
I changed the dampers again but this time it did not fix the jello. someone did mention
to tighten the wee screw on the gimbal arm of the p3p but I dont have a tool
to do this "any advice would be great"
