Align 500L 1600kv in 90mm EDF

This is a stock fan for Starmax 90mm F18, for fuselage length 1.6m. Align 500L is rated officailly at 800W, but I believe it can much better than that. Since Align's outrunner is factory balanced , it is a perfect outrunner for EDF. The motor mount inner diameter of the EDF is only 37mm. Wheras Scopion 30xx outunner has a diameter of 37.5mm. To put in the Align 500L (diamter 37mm) , some sanding is needed.
Some 8mm spacer is needed to mount he fan without touching the case base. The alumnium hub is better inserted as deep as possible to avoid wobbling.
The fan is well balanced with minimal abrasion. Most of the vibration comes from the aluminium hub as the 5mm motor shaft hole is off-center !
