If you are wanting a large coaxial take a look at the MJX-F39. I had one and as far as coax's go, it was good one. And it's full 4 channel so no more tail motor. It does cost a bit more than the s033 but is far superior in build and flight, and no signal dropout issues. I repaired a s033, and also a large FXD, for a friend, so I was able to do hands on comparisons with the F39.
While you're checking out the F39, take a look at the slightly smaller F45 fixed pitch. Then you can fly outdoors in a light breeze without worry, and have almost the same hover stability.
In case you're wondering - No I don't work for MJX.
