It's all I fly. (14x4.8) I love em. But I would NOT recommend them for folks new to RC, flying in close quarters or inside. They are especially good for AP in windier conditions (I do a lot of AP by the sea) as the blades cut through the wind and I find the AC doesn't bounce around nearly as much. They are measurably quieter and look like they mean business, if that matters to you.
(I do admit to using them to scare the bystanders back 30+ ft if I gather a crowd, saying they are very dangerous and they need to stay WAAAYY back. Had more than a few people ask if they could touch them after I landed and disarmed....)
Just my personal opinion. I realize CF props aren't for everyone, but I love my T-Motors. I can pop the original auto-tightening props with locks on anytime and I do carry both with me everywhere.
