OK Model Type2 70mm EDF

The housing is FG reinforced and is very tought. The design is great to allow more cool air to contact with the inrunner case.

The Type 2 fan is not well balance at first glance. However, I was wrong and find that the vibration is even more significant after static balancing.
I end up leave the stock fan intact and it runs smooth and vibration free.

The Tamazo inrunner is very good quality and the copper wire is wound round stator (Unlike cheap inrunner). The magnet is very strong as well. Unfortunately the case is pinned and is almost impossible to disassemble to take a good look inside.
