Goodevening, guys I have just finished reading thru all of the posts in this thread and have a couple questions before I assemble my modeltech magic extra 300 I see that most of them come out tail heavy so I plan on a big engine have a os 60 or maybe its a 61 that I plan on using I see that someone says that is not a good choice wondering why also I see people saying the fuse is weak over the wing area what should be done to make it hold up better don't want to have any weakness that can be rectified while assembling. pretty new to building but eager to start getting a few new arfs I have together over the winter this year so I can fly them next season
