I've been using a Sonic-Case for my V3 and R4. The R4 is tight, but with an R44 it will work better.
Several people have made "stilts" for the V3... one guy was actually selling them. I have some piece of fiberglass I used and taped them on in a hurry one day... 9 months later, I'm still using it the same way.
I have a pair of the "stilts", but I was looking for something with more room under the V3(taller stilts maybe). I would, also, like to attach my R-44 and battery to this.
Another option is the Rakgear bag like I use. It has slanted shelves that you can put your gear on.
Do you know the manufactures website? pics?
