I bought a couple of spinners for my electric powered JR Mosquito and found they needed the Aeronaut style CAM folding props that are screwed to a bar that crosses the spinner backplate with a hole that passes the spinner/motor propshaft. Hopefully someone will know what I mean :-)
Anyway, I've never used this type of prop before and am a bit perplexed to notice that there doesn't seem to be anything to stop the prop from folding in the forwards direction. Of course they fold backwards OK (and are definitely the right way round) but there doesn't seem to be anything to stop them from folding to about 45 degrees in the forwards direction. Do they just rely on centrifugal force for this, or have I got the wrong type/size of crosspiece, or what ?
Any ideas gratefully received,
