Hey Guys
I fly at the same field as Vinny. WE had been talking about mixes.
I had a problem with the heli ever so slightly rolling out in loops. Checked that there was no interaction off the swashplate from low to high using the Garry Wright bubble gauge. I also checked phasing on the swash plate and it all looked good. This is all on an older xcell se. Read the article in MHT and it talked about phasing happening due to the gyroscopic effect and the mass of the head. I did the mix from fore/aft cyclic to left/right cyclic and it tracks straight. Now all I need is slightly longer thumbs so I stop wiggling the tail through the loops:-)

Cheers
Al
