Mindwarp, the pinned hinges are definitely the better deal. Be sure and use thick CA and don't overdo it, if the hinge pin gets quagged with glue, you'll have problems. I'm flying an LT-40 with a Tower .46, and its a beginner's dream. You should consider adding some small triangular stock to the tailfin/fuselage joint, it's a weak spot.

This plane tends to float on final approach, you'll find yourself overshooting your landing strip. Try a 11 x 5 prop to reduce airspeed at engine idle, it helped mine. Good luck.
