First--choose the props.
Scale diameter will be about 8.5". Motor spacing?

Master do 7 x 4 and 8 x 6 3-blade.
GWS do 7 x 3.5, 8 x 4, and 9 x 5 3-blade. [9 x 5 could be trimmed]

What do you think?
Hi Peter, the props size...rough scale of the Lancaster is about 1/17th (102 ft = 72").........I reckon the full size props on the Lanc are around 12 to 13 foot across. so that gives me nearly 9" props or there about.......distance between the nacelle centre lines is 9 1/2 inches and the inners are slightly forward of the outers........so maybe the 9 x 5 s would be ok ? or possibly these 9 x 7's ?
