I am pretty sure you will not have problems with the Wire drive if you grease it and follow the recomendation on the webs I give you............... Check were they talking about the grease and also about the rear tail pitch slider because the plastic factory one broke easy and you will lost tail control.
You can made this mod:

Or you can buy this aftermarket one on http://www.centuryheli.com

Also Century has more upgrades for the GPH
