Aeronaut folding prop question

Hi,
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,
Thanks,

I have a couple of folders that would appear to be able to go 40 degrees forward but under power they don't it must be that the centrifugal force is greater than the thrust produced Kevin

Boo-
You'll find that while spinning, the blades actually rake back a bit. As for the yoke (crosspiece) they are sized such that the blades fold back more or less flush with the fuselage. Usually if the spinner is the right size, the yoke will be also.

You MUST use the spinner that goes with this style prop. It is the spinner that limits the forward movement of the blades. Been there, learned that !

Totally wrong! You do not NEED to use the spinner - the blades can't move forward due to centrifugal force. I've often flown without a spinner especially as the keep changing the root thickness

I didnt think so either. Mine seem to track fine. Interesting point to ponder tho. Anyone ever owned a UHU powered glider? They fly great.

I did fly for the first time today the Jane ARTF glider I bought from North Weald. It is a small polyhederal wing 400 electric 3 channel plane . The wind picked up but I was determined to give it a go and it coped with the conditions really well. Two flights and I can still fly it tomorrow - must be good!
It came supplied with only 1 page of A4 instructions/illustration, I suppose this is why it was so cheap.
At least this was a cheap Ripmax deal that could fly, unlike the Reno Racers that were so far out on the wing incidence that they were incapable of flght without major modifications!

Thanks all for posting your experiences. It sounds as if it should be OK so I'll try it and see what happens.
Thanks again,
