Hello! Fizz - My rudder horns are 1/8th aircraft ply painted with black marker
Tewitt - Thank you for the input! I think I will install some stall tips on mine, I wasn't liking the look of blank square wing ends.
I did add 1//2 in to fuse front, and lightened up rear fuse, my wings have no dihedral (my twin brother begged me for a non trainer trainer)
I might cut a set of semi - symmetrical foam wings to give them a try.
