you might cook an ESC ?? Just a thought.    Am I missing something 

This little guy is cute. I would just hate to see him go up in smoke.

thankfully the amperage decreases as the voltage increases so I should be fine. In my testing in the past, I've been able to run 6s freestyle builds on 20a motors. The instantaneous draw of the motors hardly causes issues and most batteries can't sustain that draw for long. 

In my case, these 6s 450mah lipos won't be able to sustain that 33a for any amount of time to worry about.

I'm going to try dropping the master multiplier based on what you said and I'll report back. Thanks for recommendation. Funny enough, there are no 6s 3" presets, but something tells me these will be the builds of tomorrow.

In the end I was running 65% throttle on mine, see here: https://intofpv.com/t-investigating-6s-o...inch-build

I also used those 6S 450mAh CNHL batts. They were a nice balance between weight and power. To step it up I also used BONKA 600mAh 6S with XT60. I tried some of those GNB 6S HV packs at around 500 - 650mAh. They are yellow and green in colour. Not great as they're liHV and also power pigtail was really short, kinda useless.

Taking it down to .6 on the pids allowed me to hover and take off, but I'm still getting random freakouts that I just don't understand in flight. 

Maybe the FC doesn't have enough filtering to run 6s even with a full-sized cap (35v 1000uf), or maybe I need to drop the pids even more. 

Today everything was fine , got out to fly, and it freaked out again..weird

I'm gunna try the UAV tech toothpick 6s tune tomorrow.
