I fitted GP 10's to mine, very strong and light retracts. Nice video in gorgeous weather! I have posted a video response with my maiden flight, and yes, with mandatory glitches! I'm hoping a D.C. rx will cure this.
Yep - they take a long time to build and to be honest you don't end up with a great aircraft by any means. Two pieces of advice - ditch the ultrafly retracts - replace them with GWS ones from United Hobbies, and keep the AUW under 610g
