I don't have and have never seen a GT M530 in person, but I can say my Kopis is pretty amazing for efficiency and air time (when I take it easy). Very happy with it!

One thing I did for better range was get the RX antennas up on top of the cage, like bug antennas. I was getting low RSSI with them down off the arms. But if you're really going for long range, you'd probably swap in Crossfire anyway. I also use a right angle VTX antenna most of the time. Both of those seem to help with longer-range, I think the antennas out the back and off the arms works fine for closer-in racing.
Thanks for this information. You are swinging me toward pulling the trigger on this thing. I bet with an 1800 or 2000mah one could probably see 12-15mins of cruise time.

Has anyone tried tmotor f60 pro vII (2207) or the tmotor f80s (2408) on the kopis?
Thinking of turning the kopis into an all out power machine!

Maybe, the biggest I have is a 1600 Truepower. On a 1550, I usually draw about 1250mAh out before landing (I only draw down to 3.5V per cell min). having an extra 250mAh from an 1800 should perhaps give another 2 minutes, so yeah, 10-12 minutes maybe based on the way I cruise.

I would think at some point the extra weight of the battery would start to eat into the efficiency, but not sure where that balance tips. An 1800 R-Line is 12g heavier than the 1550...

Try it! They're only a low kV, running in 5s would make them 3000kV 4s equivalent. If you're worried try set you throttle curve with with maximum at 80-90%
