Remember 'spray on mud ' for 4WDs?

How about 'built in prop strike' 😄

Naa - Not a strike - aerodynamic enhancement 😈

Yes, I do know that. Hence I was just joking about it. You see, calling it a built in prop strike negates it being a prop strike and thus.... nevermind. The moments passed.

The jokes on me then - I didnt realy think it was a deliberate change to the tip.😈

I like the method of adding the dynamic balance weight to the spinner 🙃😁😉

It's something I've never seen before, but maybe it works a bit like a wing tip winglet. This plane flew in, so clearly it doesn't NOT work ☺️

Yes, must be the same plane. This was at Boonah for the Dave Briffa breakfast memorial

what is the idea behind them.  do they work like turned up wing tips.

I guess that the theory. 

I remember, some many years back, that this was flagged as the next propeller performance innovation. As we all know, doesn't seem to have eventuated. I wonder why?😈

Less prop noise. Hartzell have moved on to Scimitar blades now. End of the blades is a swept wing to reduce noise as the tip approaches the speed of sound.

I think that's what I just bought for my plane actually. I'd much rather my lovely two blade wooden prop, but the pitch is too fine. So instead I'll have an ugly 3 blade carbon fibre prop
