I few the Katana for sometime and really injoyed it. The only two issues I had with the plane is the covering did not want to stay down in some area's and you had to be careful with the iron when resealing. The other was the small hole in the bottom of the fuse used to get the to the wing attachment. I read alot about the hatch mod and really wished I had done that. The hardware is standard $200 airplane hardware and nothing to really right home about.

With a Saito 150 you will need to go with a pull-pull set up or you will be adding alot of wieght to balance. I flew mine with a 30cc glow motor and had to use the pull-pull to get it to balance with the battery just at the back of the hatch.

There is a 300 at the field I fly at with a Saito 150 and it seems to fly pretty good.
