Hi all, I would really appreciate some (basic) help with selecting a new propeller.

The white metal item I got in my CORDENE kit is, well, a bit lumpy. I could spend time and effort sanding and filling it but would then be worried about its durability as I hope to sail the model when complete. The solution of choice is to buy a brass replacement - but unsure about measurements. So (for argument's sake) say I bought a 30mm propeller: which of the three dimensions (A, B or C) in the attached diagram would be the "30mm" specified for the item I'd bought?

Dimension A is the one you require.

Do not forget to specify right or left handed

the thread is the same but the direction of rotation is different and please do remember to fit a locknut ( and use locktite) so your new prop doesn't join the rest of the lost bits on the bottom of the pond

Thanks for advice Haverlock. Had picked up on the left-hand / right-hand thing but the tip about a locknut is very useful. Probably saves on a bit of wading as well as preventing a lost prop!
