Ihave the Aeroworks 50cc 300 extra. My first impressions where it to be a fabulous airplane. Everything fit perfect, covering was amazing. I converted mine to electric, 12S, Suppo 7035-9 (190kv), 110HV CC, 23/10 Zoar. Outstanding performer, even out climbing two 50cc DA's both on cannisters.
On my 6th flight, I screwed up big time, put it in the ground. Tore out landing gear, cracked the cowl up some, crushed onese fuse side for about a foot. It spring the entire frame apart right back to the rear canopy. Thats when I found out the entire fuselage is assembled using wheat acts and appears to be hot melt glue or some form of it. Reassembling required I scrape 100% of this stuff off, otherwise nothing would stick.
I certinlydon't blame Aeroworks for the damage, that was my fault, but the glue (whatever it is) certainly leaves something to be desired.
It all fixed and now stronger than original and flies as good as ever.
The only true ***** I have is the aluminum landing gear, its bends even with good landings, almost every time. Quite soft, not up to par with the rest of the plane. My buddy's identical plane on gas suffered the same issues, he replaced it with the CF unit, no trouble since. FWIWflytreetimes
