Was this ever resolved? I'm having the same issue. Brand new eachine wizard, I've not been able to get it off the ground at all, it never seems to have enough lift to even attempt taking off, it just sits there and spins.
Here's my setup:
FlySky Transmitter with fsia6b receiver connected via ibus
Battery: 1300mah / 75c / 11.1 3S (at time of test, voltage was around 3.75 per cell
Stock purple props, I've triple checked they're on correctly: props labelled with R are on the motor stems with the black hex nuts, non-Rs on the silver
BetaFlight 3.1, the receiver section shows a min throttle of ~1004, max of 2000. Under the setup tab, the craft's orientation seems correct, it pitches and yaws according to how I turn the drone in my hand. I've calibrated ESCs many times
Like I said, this is brand new, no other problems in terms of setup, I've religiously followed Josh Bardwell's setup video. Any ideas on what to try next would be greatly appreciated.
Thanks!
