RE: Composite ARF 2m x 2m Extra build
Yes.. the electric conversion kit also contains parts for use with the Plettenberg outrunner. I don't know the actual motor number though. I'm also not familiar with the power level it produces in relation to the Hacker (which is ballistic!)
As for the noise of this setup, it's not bad and will actually meet the F3A noise limit over both pavement and grass, and once in the air you can't hear it at all.
