How do you like 4in props on those motors? Do you think you'd feel a light HD cam on a build like this?

The brand new tattu 850 gets me 4:30. The crappier Apache (20mohm resistance) get me 2-3 minutes. so its actually surprisingly efficient

What is the AUW (no Lipo)?
I got 3-4 mins on a Pulse 650mAh 4S.
Still have to try the 850 4S Tattu

204g as is. I could drop another 20-30g if I swapped some stuff out but I like it as is.
