Taigen 390 motor conundrum

[MrChef]

Sooo are these motors 390's?

I just bought the last pair in stock here at Taigen U.S.

This is what their site shows-



These are what was sent-



Taigen advertises 390's in their Tiger I-



Soooo I compared them to all of the Tigers-











Soo who can shed some light here? Are they the same? They sure look the same as all 4 on the tanks. But the Blue cap?

And are the Taigen 390's the same as the HL 390 Reds? or Blues?

I used to think I knew but now I'm confused. Please enlighten me. Thank you...

The easiest way to tell the difference between the different motor types is the length of the can. The can on the 390 should be 47mm long and 28mm around according to the Taigen website. The 380 motor should be 38mm long and 28mm around. The end cap color is meaningless. The color of the motor is pretty much meaningless also, but the Taigen 390s are slightly different than the HL 390 Red motors. If I recall correctly, the Taigen motors are a little faster RPM than the HL motors. Those two both look like 380 motors to me. Typically the Taigen 390 cans are a matte finish - it kinda looks like Parkerizing rather than powder coated like those. The additional can length is where the additional power comes from. There are more windings and more magnet mass.

HL Blues are a 380 motor that's supposed to have more torque than a standard 380, but I've never used them.

Well they definitely look to be 47mm long-





So I guess mystery solved They're All 390's.

Thank you
