AirCore .40
This is a great trainer! Yes, it is a little heavy and needs a .46 engine (a tt .46 with a 11x5 APC is best). I always keep a trainer in my hangar to train newbies with and this was the solo bird. Yes, it had been crashed a lot and it held up with at least 14 solo flights in the past 3 years. I flew it regularly too when I didn't want to concentrate too hard. Sadly, mine finally started showing its age and I had to retire the fuselage but kept the wing.
I'd buy another one again, by the way, mine flew inverted quite well and was awesome at fun fly competitions.
