i feel that there is no reason that everything can't run off of 6S. I've been experimenting with a multitude of micro builds all running off of 6s packs. A micro cinewhoop was one of those formulas I hadn't yet cracked.. I had looked at a few different frames including the Beta FPV95X V3 As well as the Geprc cinelog. Amazon actually had a really good deal on the iflight protek25 pusher. I had looked at a couple of reviews about this and the consensus was that it was durable but it was heavier than other options which actually was a turn off for me, however this sale was I believe 20% off so I decided to pick one up and try it out. Iflight as always impressed me with the quality of their builds the TPU and the carbon all the details around the builds are pretty impressive. Anyway I ripped out the flight controller I replaced the motors and here we go a 6s tiny 2.5" cinewhoop with a dry weight of 137g. Maiden flight was ok with a 550mah 6s lipo. I will try it out with a 300mah 6s next. I should be just over the 200g mark all up with an insta360 go 2. of course expresslrs on ghost hardware.

UPDATE! GNB has put out a 530mah 6s HV battery and I am 245g with that pack and the insta360 go 2! Super stoked for good flight times and a great pack that keeps me sub250g on both this quad and my 2Fiddy builds ^_^
