This one fits one eighth inch motor shafts. After ordering four of these spinners, I was pleased with their prompt arrival in good packaging that had protected them from potential damage. Very well made and easy to fit provided you have ordered the correct size to fit your motor shaft. Surprisingly light. Good looks. Be prepared to have to adjust the cut-out which has been made to suit coarse propellers. Being metal, a quality grinding wheel on a dremmel or similar will be necessary, particularly if you have a thinner low pitch prop. Expensive, I think, Recommended, especially if you can get it cheaper.Very nicely finished spinner. The SF 10x4,7 and 9x4,7 e-props fit perfectly in that spinnertimo acabamebento, preciso e robusto, gostei muito.Great looking spinner...Great value for the money.
It is impressively light and well finished.The efficiency price weight holds quite in mind..Otimo Spinner para pylon race. Com certeza vai aumentar a performace do seu modelo.
Recomendo.This thing really has some stick to the shaft of my Align motor for a hot dog racer.nicely made, only the very slightest bit of out of centre spinning. Well not off centre, the hole is not perfectly aligned with the Axis of the unit. At the base it is perfect centre, Maybe 1 mm in 30 out of dead true at the top., this is not an issue, and it takes 4050Kv on 3S. I would like to see anyone else giving it more revs than that.o SPINNER NOTA 10!!BEM ACABADO..PERFEITO...E QUASE DE GRAA.Great looking spinner, looks like its spins true, easy to fit and looks great. fits on shaft of Turnigy 2217 perfectly and hasnt come off yet. what more could you ask? i will buy more.Sehr gute Qualitt! Kann ich nur weiter empfehlen.
