On the fourth flight I got bold and tried some loops and rolls. While rolling out it stalled and got into a spin. It started at two mistakes high. Should've flown it three mistakes because after almost recovering twice it hit. The firewall popped loose and a motor wire broke.
No other damage.
I replaced the motor with an almost identical Racerstar BR1811-2000KV. Here's the maiden flight with the new motor.
I amp tested with a 7x3.5 prop because the new motor KV is higher and that size prop is bigger than recommended. At full throttle it only draws a tiny 2.5 amps so it's cool. It now has more thrust than the first motor did with a 6x3.5 prop so it is an improvement. After trimming it out I'm happy with how it flies. A few more flights and I'll try those loops and rolls again.
