I'm not sure what the weight is. i won't be on here for awhile after today so I probably won't post a flight report. The motor is going to be just fine, though. If you put the servos in the tail as I did, you'll need the weight for balance. If you want to fly gas the G26 is a good place to start. There are plenty of airplanes it works well with. I'm sure this will be another. A glow engine such as the OS 160 or Saito 180 will have a better power to weight ratio, but I think the G26 will be plenty. And then fuel is so much cheaper....
I think the key is wing area and the Katana is at the bottom end of what I consider workable for this motor in this weight plane.
