Nice light weight wheels. These are great for small FT swapables.Very nice seeming wheels, mine all weigh in at less than 1.1g, 30mm is a good size for *very* short grass (By very short I mean 1cm or less, think a well-used cricket crease, maybe artificial grass) or general asphalt surfaces, concrete drives and the like, and also obviously fine for indoors. Smaller wheels on micro-flyers tend to stop dead causing nose-over at the slightest bit of twig or gravel outside. The hole is I guess for a nominal 1mm spindle - I found 1.2mm piano wire to be the perfect fit, nice and free running with very little side to side slop, but 1mm works fine too. Anything more than 1.2mm the wheel will be stiff or need drilling out.Ideal para pequeos modelos. Las usare en mi AcromagnumAs they say, superlight and not only that. They're super cheap!Perfect for my landing gear purposes, even the color fit my design!
