The Advance is the latest generation of motors developed specifically for F3A (Precision Aerobatics) by Plettenberg Elektromotoren in Germany.
This motor is a new concept, being a direct drive inrunner, it should in theory enjoy better efficiency than an outrunner, yet retain some of the benefits of an outrunner by not having a gearbox.
The motor is similar in specs to the 30-10 outrunner, 20 poles, 10 turn etc. but has a slightly higher kV.
