I do like the Yellow scheme, but have not seen it in the UK as yet.

Ian is quite correct, on my AXI 4130/16 I am using a 16x10 pulls it around with authority, it will be interesting to see what you end up using, you may find that ground clearance problems stop you from using the ultimately correct prop.

EDIT: just a thought an 18x12 cut down to 16 would be much wider in the tip and may give you the power draw you need without the ground clearance problems.
