OP,

the AW Edge is not really a good 3D airplane, atleast not with the stock engine size. I have heard people talk of putting 100 size 4C engines on it

The Mojo is a all out 3D but I am not sure how comfortable you will be doing sports flying with it. If you want hardcore 3D, thats the best to start with

The Phoenix Yak is just sports

I would recomment the GP Reactor 46. Get a 65ax or 90 size 4C engine for it. I am flying a much abused Reactor with a 91FS and it flies read. Yesterday, I hovered it half a flight and then flew sports pattern for the rest. Thoroughly enjoyable airplane and mine isint anywhere near ideal in terms of built (banged it several times, this is the 4th engine on it)

If you do go for the Reactor, a lot of guys can offer some strategic building advice

By the way, the Razor is similar flying, but smaller
