I did mention this previously as something that could be done.
I would still like to heir Jetcat comment on this issue. When you look at the bigger picture you still have to wonder about Jetcat recommendations and how you are going to follow these recommendations otherwise, I can assure you that when something goes wrong this is one thing they can try and put the blame on.
I do like Jetcat engines and have a few including a P90 which is yet to be delivered but I never knew about the internal filter.
