Triebwerk Here!

[bentleya]

so people have these in hand and we still don't know if they can scare away frogs?!?!?

IF i can find some frogs i will give it a go

I'm still waiting for mine. International shipping takes forever.

Anyone with some in hand care to post a video up close so we can here them? I'd like to know how they sound when undervolted.

Martin, i'll hock them up them up tomororow around this time, depends what time i get in .

What RPM's would you like readings of sound at?
