RE: Picco P-zero 0.8cc
I'd set up for the Turbo plugs.Or Cox if possible. Easier availability than Nelsons at the hobby shops and more heat ranges. Also the exposed diameter inside the combustion chamber is less than a Nelson. About 1 mm makes a difference on a little motor. A .40 not so much. 1/2A speed used to allow any fuel even when the bigger classes restricted it to 10%. I believe now it is 10% in 1/2A too. The AMAuses Sig fuel at the contests and have a pretty good distribution network to get it to the contests. The Canadian speed rules are whatever the US AMAlatest version is. The North West has some of their own rules like F2D Proto (good one) and Perky where it pays off to be average. No one on this side of the Rockies flies speed in Canada any more. PM me if I am wrong. The Picco has nice long 2.5mm hex head screws holding the head. The GZ and CS have shorter slot head screws that I could see need lengthening and tapping deeper.
