Tiny blades

RES model's climb was very slow on 2S so Neil advised 3S with a smaller prop. however my spinner was for M3 pins and the new prop was M2. The compromise solution he suggested is fiddly and involved inserting short spacing bushes to convert a 2mm screw and nut to 3mm but it does work and my PURES climbs more strongly.
