These are great quality spinners at a reasonable value. Some slack in bolts and you might need washers inside the propellerblade space to get it to not wobble. But really universal. Have not yet met a blade I couldn't fit on these. Multi adapters make it fit most motors.this spinner is not bad for the price, the blade fasteners are too small for the Graupner blades I use so I replaced them with larger ones and works greatNice quality and design.Looks good however fitting top-bottom is not quite exact.Preis Leistung Top! Danke HKI ordered 3 of them. One has 3.17 adapter which can't be put on appropriate shaft.good quality spinner , balance is good , can be used with an ordinary prop just have to open grind the slots out moreprecise balanced, good qualityIt' s a good product, not so cheap but well made and very versatile and usefull. The prop's hub is 8mm broad, prop's screw needs to be secure with some medium threadlock (there are no locknuts). The axlesholes of the adapters are not too deeply drilled (about 12 or 13 mm /- half of an inch,), so, with some motors with " a long axle" (as the Towerpro 2409-18 and similars) you shoud be obliged to shorten the (fragile)axle to suit the spinner correctly. Otherwise, you can be fully fully satisfied with this product.
