Roger,

29 lbs seems pretty heavy. Its been a long time since I did that design and I havent had one for quite a while so I dont remember the exact weights. In fact the last time I flew the one I had was the same day we shot the photo in Rcheliman's avitar and thats been hmmmm, probably 5 years or so.

What do you have in your for batteries etc?
I believe mine was in the neighborhood of 24 to 25lbs with a ZDZ 80 nd about 2.5lbs of weight in the front of the cowl. That was with rudder on pull-pull (I think) and one battery pack on the rx.

The new SU-26 comes out a LOT lighter, more in the 21 to 23 lb range. 23lbs seems unrealistic for the SU-31 though, but 29 seems very heavy too.
