mgreenberg,

I have one of the Quest G2 which I have been flying for over a year. It is a great flying plane, and excellent quality. I have a YS 1.10 with no additional weight to acheive the proper CG. The answers to all your questions can be easily found in this thread regarding the "QUEST"

Have you called Ultra-RC and spoken to them? I do speak to them and the service has always been very good.
