RE: Help! I need a dimension for a E-flite Park 370 Outrunner Motor?
Sorry, don't have that motor, I tracked down the E-Flite specs. hopefully this helps some.
Shaft Diameter: 3.17mm (1/8 in)
Overall Length: 25mm (1.00 in)
Weight: 45g (1.6 oz)
Overall Diameter: 28mm (1.1 in)
Diameter: 28 mm (1.1 in)
Length: 25 mm (1 in)
It should be 1" from the back of the motor where it mounts to x adapter, to the start of the motor shaft.
