I have a Seduction Freestyle (non Ono Special) that I finished about a month ago and has about a gallon through through it. I have an Irvine 53 up front and a 4 cell AAA Ni-Mh battery pack way back in the fuselage underneath the elevator servo and I still need about 1 oz of tail weight.

I'm still a beginner with pattern and 3D flying so I can't comment too much on the flight characterisitics but overall I'm fairly happy with it. The first flight was definitely an eye-opener. Immediately upon takeoff there was a severe left roll out-of-trim and the controls were MUCH more responsive that I expected, even at low rates, so the plane was gyrating all over the sky until I got the trim figured out and the plane under control. Turns out this plane has a wickedly fast roll rate and it doesn't need much aileron deflection to get it going. I had mechanically set my ailerons up with an ever so slight left roll so that's what caused the left roll out-of-trim condition. Luckily this first flight took place out on a California dry lake bed so I had plenty of airspace to get it under control.

On the plus side, I constantly get comments on how good the plane looks when I take it to various flying fields. I did mine in the clear red/opaque white scheme on the kit box so it gets a lot of attention but the scheme is kinda hard to see in the air.
