What size engine do you recomend for that plane ?

I built the 40 size super sportster from the kit as my second plane, second kit. It's awesome. It went with me to the field just about every time I went. I've had it four years and I'm now recovering it with ultracote. It was my second kit so my skill level on the monokote wasn't that great, and the years of flying have taken their toll. By the way, this is my first ultracote covering job and I am firmly in the ultracote camp.

I'm now flying a great planes spacewalker. It's too big for your .46 engine, but it's a great flying airplane. I agree with the comment that it's not as agile as the sportster, but it's a lot of fun nevertheless. There is a 40-size spacewalker arf available now by seagull manufacturing, and I'm vaguely aware of one by kyosho. Don't know much about those planes.

As far as other good flying .46-size second planes, take a look at the world models super stunts. It's $99, 60-plus-inch wingspan, lightweight, agile/stable flyer, ultracote covering, a lot of fun. I just bought a second one in case something happens to my first.

if you get the 60 sized plane, a good quality 60 will be plenty! i run the .65 la in mine, and my buddy had tt 60 in his and it was more than enough.

I might be interested in a plane to help you out,what do you have,i'm looking for a first plane,like trainers.PM me if you want.
