Just a few questions Mike, where does all your hanagr 9 planes balance at? With the GT-80 installed, Where does the CAP 232, Extra 330L and Sukhoi Su-31 balance at? Did you add weight to get them to balance? Enquiring minds want to know!!!! I have all 3 and none of them balanced like stated in the ads or instructions, all needed some weight. All of them have the recommended engine Zenoah GT-80, all built according to the instructions. Come on Mike, where did yours balance without no weight? Did you add weight to balance them?

I'm hopeful that almost everyone that is an Aerobatic fan is a Sukhoi fan,
just waiting for a truly refined model to become available. This ARF model
is approx 1/3 scale, 97" span, 1810 square inches. 80cc engine. It comes our
a little lighter than our H9 33% Cap. Approx 24.8 lbs w/ a GT-80 and 23.5 w/
a ZDZ 80 (Single). It took about a pound of lead in the nose when I put in
the ZDZ. Takes no ballast w/ the Zenoah 80. Quality is excellent, and is on
par with, and maybe a little better than the Cap.

Also from a previous post:

with the GT-80, why did it need so much lead in the nose? I thought this plane was supposed to balance OK using the GT-80, supposedly Mike McConville's did with the batteries behind the wing tube.
