I love the emax tinyhawk, even though it is 'only' 1s it is well suited as an indoor racer and they've recently started a spec class near me just for this. My full review of it is here. One one common furstration however is that the FPV camera can come loose in a crash and if you try to push it back in the wrong way you can easily snap the tabs on the frame that hold it in. I've prepared a simple step by step walkthrough heretht will allow you to fix it safely in less than 5 minutes (I timed it!).
