Andersons, I also believe a 4100 6S battery won't have good flight time/performance, might be good enough for 401 as long as it's not too windy & you are careful with your throttle management. I've owed a Wind 110 for 4 years & run it on 8S 4900/5000mA batteries - 7min flight time - Hacker A50-16L on 18x12 - used to run 18x10 but 18x12 is better. IMO the Wind 110 flies much better at 2200W vs 1900/200W. I've seen a Wind flown on 6S & was not too impressed (1700-1800W), OK for sport flying though. This is just my opinion, I wish you the best of luck with yours. Let us know how you get on.
