I've been using the core system for around 6 months now and it's been ok. It's got 10 model memory on it and lots of other stuff that i don't really use
. The only problem i've had with it was this weekend when i managed to snap the Aerial wire in the receiver, but i put a post on here and chi3f pointed me in the right direction. I also see a lot of them at meets so they must be half decent. Good vaule for money me thinks
