Making an article for a magazine is usefull to create such information.

The article is now at the publisher with lots of pics, soon I will get a rough PDF file to check it out and correct where needed.

Hey... sorry for the lame question, but what size is a mamba BL? What dimension are the motors measured by? Is like cross section in MM or circumfrance (bad sp) in mm... something like that?

"... numbering scheme is very simply based on the physical size of the motors. The most basic sizes are 360/380 and 540/550. These motors are 36 or 38 or 54 or 55 millimeters long... Easy ?"

The Mamba motor is about 30mm long, right homer?

:p

no. I stated above, its a 200 size.
the chart was based on brushed motors. BL motors and their designation is not the same. (ie. no set standard that I know of.)

If the thing with the length would be right, hy is a 180 size motor 32,1mm long?;)

These are the mabuchi specs. Especially the 280 motors with external brushes may differ in length, but the diameter and mounting holes will match.

370 Sized motor: dia 24,4mm / length 30,8mm
(Speed300,LRP Fusion, Orion BigBlock)

280 Sized motor: dia 23,8mm / length 30,5mm
(Permax280,Reedy MiniMax)

180 Sized motor: dia 20,4mm / length 32,1mm
(Speed320, Micro/M18 Stock motor)

GPM has a High speed and a high torque motor with better performance. With the same performance there is the Graupner speed 320, Robbe Super 180, Xray 180, WWS 180 and a lot more.

The Graupner 320 is a good average performance motor with a long life.
