hi
I have a Turnigy 20x8 propeller turn up and the pre drilled hole is larger than the Zenoah 38cc shaft by about 1mm ( guessing not measured yet) how can get this sorted ? Looks to small to machine a collet , in the past I have used metal from drinks can as a shim to go around the shaft for zero play . Has anyone a better way to tackle it ( when I say better I mean more elegant) thats fairly easy to do ?
