You're right
@bobomet I've really struggled deciding what to do, counter balance or not, what's safe, what's over the top safe etc. etc. The one think I'm convinced of is than an ND is a necessity for aerials... not a preference. The quality of SRP lenses is just incredible so I made a choice. In the end I look at it like this.... Pure wind, the resistance of that wind and flight at say just 12-15mph produces MUCH a greater force on the gimbal motots than the 7g of the filter. The gimbal was engineered with this in mind otherwise none of us would be able to shoot anything unless skies were absolutely calm, zero wind and traveling no faster than 5mph. That said I've yet to notice any visible or audible motor strain, hibernation or drifting. Gimbal calibrates fine everytime and stays level the same way it would without an ND. Disclaimers are everywhere. Makes me nervous too. But that's good old CYA and I guess I'd do the same if I were an aftermarket product designer.
Apologies in advance to the moderators as I may be veering too far off the topic of this particular thread. But a lot of folks, including myself, have had huge issues with the "PP build impressions" so showing an alternative that works helps folks make informed purchases I thought.
For what my two cents is worth. (The PP test is a little shorter as I couldn't get the filter screwed on all the way and feared loosing it if it fell off.)
