I don't have too much of an issue with the roll axis most of our problem seemed to be with our panning movement. I will try Joes method and update my firmware and give it a shot. I flew it down Rio Grande today, we had it too stiff this time. Our panning jitter was fixed but we had the engine vibration it the footage. Also I must note that for testing I am using a cheap Canon vixia handy cam that I bought on craigslist, so my camera is significantly lighter than the 5D or other DSLR types. I don't know if this is factor.
