Hey, i had all 3 sizes, prefered the 46 size with 92 (old) Saito, correctly setup its knife edging alright, tips pins are cool, for hover its a great trainer, harrier okay, if you want affordable entry level 3D machine and practice for larger stuff get one. The Reactor was just rattling apart behind a 82 Saito, yes flew better but didnt last for ___. depends on what you want. Actualy thinking to get me another one, since i wore out 2 of them and still like it
