I haven't checked the Graphtech offerings in a while mainly because I just don't think I would use them again for IC engine planes due to their tendency (verging on certainty!) to delaminate. I got the CF gear from Aeroworks for my 50cc Yak (looking very much like a Graphtech product) and - guess what?? - it delaminated within a couple dozen flights. There is a reason the vast majority of IMAC guys use aluminum LG.

Getting back to the gear for the Phx Extra, it could be that they no longer make the CF gear for the larger Fliton Extra 330 Freestyle, since that plane has been discontinued by Fliton. Bottom line, give them a call to clarify what they've got.
