I didnt even know what an AirO was until it landed in the shop Had a custom build made up with D521s, Magura's, Bomber Z3's (I think). Was indestructable, but weighed a bit! Could huck it off (at the time) drops of about 5ft with no problems. Just dont have the balls to do that any more
Sold it on ebay for a pittance as the missus said it had to go
