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.😈 1

danny_galaga Posted June 24 Author Posted June 24 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 ☺️
Thruster88 Posted June 24 Posted June 24 Q tips on a PA30 with a great rego, it was at old station this year.

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?😈 1

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 Edited June 25 by danny_galaga
