Mini titan has developed a squalling type noise that is intermitent but seems most noticable when the throttle is reduced a bit going from ff to hover.Any ideas?

mine made that noise but it was coming from the motor when I switched to idle 1 or 2, the increased RPM caused the motor bearings to make the noise. Swapped the motor out and mine went away.

Who raised the ground since I took off?

It happens to a lot of people, I had it on my E325 and it did happen once on the E325SE, I just put a tiny drop of magical oil on the top of the bearings on the motor and let it penetrate.
Don't stress about it too much, it will keep running.

Mine did this also.It was wear on the pinion.I changed motors and it still did it.Slapped a new pinion on it and the noise was gone.That was the pinion that came with the kit and had hundreds of flights on it and has been used with six or more main gears.

I had this same problem, plus the motor was not keeping a constant speed. Swapped the motor out for a JGF500TH with 14TH pinion, it now runs better than stock with a higher headspeed.
