Haha I'm not too concerned with criticism of the propellor ... I've always found them impossible to draw, that was just a go at it to see how it turned out. I drew it from scratch but I freely admit it's terrible!
Anyway, I found this picture of the T45 prop (adjustable bolted propellor is what I found from Rolls Royce) and had another bash at it, but I have to say I just can't do them:
Thanks for the help
