I have four of these beasts. I've been gathering upgrade parts for the Hasbro Hero Falcon hoping they will work. Haven't yet unboxed one of my SMT kits to test fit the parts. Stupid to buy parts when I haven't test fit parts to see if the Hasbro and SMT are compatible. The kit is large. I love it, but it does need some work to make more accurate. I have been looking for build posts over the years to steal ideas and techniques. I'm a lurker and thief when it comes to model building tricks and upgrades. I learn from other's mistakes so I can avoid them.
