The guy i talked to works for WIM ROBBERRECHTS&CO a Belgium Aerial filming Company. After asking via email if there really is a mount for the Cineflex on the market they answer was NO, but someone is working on it.
Ive worked on only very few filming jobs, but it was enough to see that their is lots of customer interest for a solution to put the cineflex onto a cheeper helicopter.
I think a nose mount like the one for a 206 with a moving counterweight would work for the R44 as well.
