I think a lot of people have been down this road, I have. On my return to the hobby four years ago and a visit to my LHS, I was recomended to get a Firebird Freedom. It was only a couple of weeks ago after hanging on the wall in a bashed up state I thought I would give it another go. I stripped out the electronics, and put in a receiver from my 2.4 specky. It still flew like a drunken penquin, and the dustbin men have now taken it to the nearest landfill. After stripping out any useful bits. Since that big mistake of a 'begginers model'. I have Superflys, Easystars, TM400, Slowstick, that are all great flyers. I would also mention that when I got an Art-tech Wing Dragon Sportster. It was also a bit of a lame duck. Removeing the Brushed motor and radio, and replaced with a brushless setup and again 2.4. It now flys like a dream. As from earler sorties it was also a bit beaten up. And as I like it so much I am in the process of building another from spares. Again it will be brushless and 2.4 Spectrum radio.
