That's my interpretation at least. Corrections from last nights posts;
The 2849-2300kv or 2849-2200kv is 49mm long but without the bearing ends is a 30mm can. The 2839-3000kv is 39mm long but without the bearing ends is a 26mm can.
Freewing isn't attempting to be misleading in their manor of measure because others use this also. May be a carry over from classifying outrunners vs inrunners.
Can't wait to see the 3D version and what some take delivery of from BH and R2F.
