hi all

have nearly finished building my jet sprint, just waiting on cooling tube atm.

i was wondering how other people have turned down bigger props into impellors as spares. And if i were to buy a propellor to turn down to a graupner mini jet impellor what sized prop (diameter and pitch) should i buy, and how should i go about turning the prop down.

i ask because i want to run my jet in small streams and the like but dont want to go chopping up the entire underside of the jet unit to fit a mesh that im still a bit unsure on. would the standard grill that comes with the mini jet, stop a majourity of "rubbish" eg stones etc entering the jet unit?

thanks
