I know it is more than the 3.5 lbs that they have listed on tower.

I am still trying to get mine flying right, but I have mine set up on low rate to the exact manual spec's, and the aileron maxed on high.

...all in all it is a good plane for the money. It does not seem to have enough rudder to do a really great knife edge, and I am trying to work an issue where it rolls out on tight loops. But for 109 it could be alot worse.

good luck!
