Thanks for the advice. I ended up sticking with what I know and bought the CL Racing F7 Dual V2.1 stacks. A big factor was that I could afford to get 3 identical builds going that route so after a few weeks of building and a couple hiccups, one stack just melted down for no reason, flew a pack landed, went to the table and switched out the packs and poof was only the 4th pack!! But they replaced it, and on FC had bad gyros the quad would ya to the left when hard on the throttle. Boy that was exciting to be flying straight and hit the throttle to split s and be suddenly 180 degrees to the right without any yaw input, I finally have all of them built! Merry Christmas and Happy Birthday to me!!! Here’s pic’s of two of them. The third one is the same as the orange one except has iFlight Xing 2208 1800kv motors instead of the Hyperlite 2208 1900kv motors on the other. I also picked up a rebuilt Hero 7 and gotta say Hypersmooth rocks!!
