Default RE: Patriot 40 tail wiggle at speed

I've been told in the last few flights of my Jett 50 powered patriot that I have a flutter issue. I'm not hearing it and I know what it sounds like. My buddy says he's hearing it slightly when coming out of a dive and doing a low flyby. My rudder has a fair amount of free play but due to the internal pushrod/torque rod setup, I don't see any way to minimize it other than to disconnect the rudder and try and run an external setup. I also added some more weight to the tail to get it to rotate a little faster off of grass and am still close to the suggested CG. For level flight I have some up elevator trimmed in. Not sure if my wing incidence is off so I might check that also. Anyone else experience these conditions?
