The unit appears to be well put together. Comes with bullet connectors and heat shrink which is useful. Bench testing at close to or over its rated capacity with a 5x5 prop, the unit appears strong and remained cool to the touch. Only issue is the shaft is NOT 2mm. It is 1 mm with a ground flat. This caused issues as I was anticipating receiving a motor w 2mm shaft size and had prop adapters to suit.
