So ours are going to be identical, except the battery. I have TP 2100mAh 4 cell and EON 2450mAh (or something like that) 4 cell batteries. Depending on the wind situation I'll use either one of them (I got 2 each). However, whenever I buy new batteries, it's going to be Zippies. Igot a few 3500mAh 4 cell and 5000mAh 5 cell (for different applications, of course) Zippies and I don't see anything wrong with them.
