Roger, go by the consensus.... move the CG back. If it doesn't work, go by my suggestion: Move it forward !!!. LOL.
Remember, tail heavy airplanes don't want to land !!!!
In fact, the way I figure out the correct CG location on my planes, is by the landing behavior.

Also, your ''slightly nose down attitude '' on the approach is not helping either. As a hint: you have to always be able to ''see the bottom of the wings'' during the final approach. If you are able to see the top of the wings, you are in trouble !!!!

One thing is to land, and another one is to fly low and touch the ground.

Thanks Jack,

The Bandit does have very big flaps which when extended, to me at least, it does give it a slight "nose down" attitude when on finals. Weather that is real or imagined I am not sure. I'll try to take more notice next time, and use your tip at looking at the under surface of the wing..

Edit

I just found a pic of my Classic on finals. (It is much easier to land and I don't have have the same ballooning issues with this model. It is of course much lighter).. This photo is on finals at about 15' altitude and it seems to be sitting pretty much level.
