46 will be great on it..... They are great planes and will fly slow but will also do some pretty decent 3D as well... About the only thing I don't like is the clear Orange Covering... Can be kind of hard to follow which way is Vertical on it... I put some white strips on mine after I pancaked it into the ground, thinking I was vertical and wasn't... Pretty tough plane.... A litte CA and epoxy and it was right back up.... FYI though it wasn't a real bad panacake... The guys at the field said I had it pulled out, all but it lacked about 6 inches, so it was not like a nose in or anything.. Of course I don't know of any plane that can take a nose in other than a duraplane...
