@@OHHP3712U I am not sure if that helps with optical flow issue,it calibrates the sensors in the gyro. But calibration never hurts.

Two different functions. Trim will level the gyro so that it hovers in place.

@@winstonsmith7801 the issue I think is the inherent phase angle of the blades. It’s only noticeable when she flies slow going forward or rear and coming out of a hover.

@@Flight6677 Is it because of the 5 blade head ? or flight programmer issues ? , The C 123 with 4 blades seems to fly really well.

I will be getting the c190 looks so scale, from other channel vids they suggest its the optical flow trying to reposition like an auto pilot. If unplugged it flies much better at lower flight speeds.

@@cjb405 that is correct and I have said the same thing. But sometimes when it works it’s really cool.

go to RC ERA website and order direct. www.rc-era.shop/

@@Flight6677 Thank You! So Ordered! 🫡

@@Flight6677 Had to go back to RC ERA Again. Turns out HeliDirect App said was In Stock, when in reality they were only Pre-Order. So Cancelled Both Heli Orders and got Refunds. Banggood order would arrive 7/30 - 8/9. Too late. Ordered direct from ERA. They Shipped my Batt fast so hoping C123 will get here faster too. I have a local Demo Event on the 27th. 🤞🏻

Next time

Yes I have the H145 and I think to buy this one for the upside down feature 😊
