Questions about Revo G2R and 6s Lipo.

Read the sticky in the BL section, which should explain things KV wise;

I would take the Neu over the 1950; 1950 has got poor threads for mounting (too thin) the delivery time of the 1950 is ~2 months, and the 1515 has more power and seems to run more efficient. (and it's nicer build) since your controller is an MGM (i assume you need to buy that too?, you do need a newer type of software in order to work correct with the Neu motors, since this is a 4 poler) nothing is stopping you to get more bang for the buck and go with neu.
