Plettenberg vs. Neu?

[zeropointbug]

Well, first of all, take into account the mass of the Pett. and the 1521 and compare the Kv., then you should be able to make some assumptions about peak power output, as well as which would have more torque. For the same Kv. though, the 1521 should murder the Plett., even a 1515 should be more powerful.
