  • Max output power: 1900W/2750W(5sec)
  • KV value: 1600KV
  • Stator Arms: 9
  • Magnet Poles: 6
  • Dimension: spindle 5x45x71.7mm
  • Weight: 267g (aprox.)
The stator size seems to be 3527, which means 35mm wide, and 27mm tall.

I am not able to find a suitable Xnova replacement motor of similar size and kv.

The closest I found was the Lighting 3225 -1100

The Diameter appears to be 50mm vs 45mm of the Align. The OP needs to figure out if it will fit. At least get out a ruler.

The other thing is the gear ratio will need to be changed the Xnova has a Kv of 1100 while the Align is 1600 Kv. Or run a higher cell count pack & esc. Or get a new pinion as suggested earlier. Or run a much lower headspeed. Or have XNova rewind it for a higher Kv...
