I definitely concur with the CG, canopy off, just behind the tube. I just adjusted the expo to about 55% in the ailerons and the feel is much softer now (as expected...) Mine started out very heavy with the Hatori pipe, Hyde mount with the integrated nose ring, stock wing tube, etc. Just weighed it this weekend and now it is 10 1/2 lbs with the Aeroslave pipe, hyde with a homemade wood nose ring and a new carbon wing tube from Jerry Budd. Snaps great, spins are pretty darn nice with just rudder & elevator. I still have the whistle during the snaps... But I kind of like the sound! LOL Everyone wants to stand out, right?

Now that I have changed everything, time to fly it and get used to it again!

Good luck with yours.
